The Practicalities of Multispecies Habitation in Sci-Fi

[@soul1d]

These concerns are actually how I imagine xenophobes get their growth bonus in stellaris and similar games that give the same general buff to being xenophobic. It is not that they are growing faster, it is they do not bother with what other species need for the most part. The Drs.* are trained for one species, and food is for one species, the infrastructure etc etc.

Such as "show me your North hand" they would mean the hand on the North facing side of your body... really fascinating and begs the question, do we all have this ability but it's undeveloped because we don't use it?

Yes! That's one detail I loved in Star Trek: Enterprise. Dr. Phlox was always tending to his menagerie of animals from various worlds, showing the kind of researcher mindset needed for a doctor going into space for the first time.

[@mnxs]

story-wise, I could see a veterinarian also being controversial - "you brought a doctor for your animals to treat me? am I so below you, human?" plus there's the considerations that alien biology might well be extremely different - a vet might have an advantage in terms of different body plans, sure, but on the very low level, every single (Earth) animal has a biology that will be quite similar to humans, and very different from that of aliens. For emergency and trauma medicine, they could maybe be useful, but for anything complex? Hit and miss, at the very best.

[@michaelmutranowski123]

That's what I appreciated about the first Men In Black movie, they actually talked about aliens being on a different time schedule than humans. Zed said "it's a 37 hour day, you'll get used to it, or have a psychotic episode.". Another thing that I don't see alot of sci-fi talking about is atmospheric pressure. There's no way that an alien who breathes methane could live in the same kind of environment that a oxygen-nitrogen breathing alien lived in.

[@Techburn997]

Funnily enough if you break down the 37 hours into thirds it isn't too bad of a work schedule. 12 hours in the office, 12 hours for yourself and 12 hours of sleep in a day and a half Earth time.

[@MagicScientist]

Throughout the series, it's implied that he is actually a brilliant physician when it comes to aliens, and he's simply out of his area of expertise with humans. For example, in season 6, episode 18, Mom tells Zoidberg that he could have been a millionaire with his own research lab if he had worked for her.

[@JBEEPO]

Nobody will mention White’s “Sector General” series of novels and short stories? They deal with a space hospital that treats humans as well as a bewildering array of non-human extraterrestrial species; the place is a huge space station that has to provide environments and supplies for a wide variety of physiologies (oxygen, chlorine, methane or superheated steam breathers; species that live in temperatures ranging from -80° C to + 250° C; a huge variety of biochemical barriers; translation and communication issues; the problem of being able to treat someone not of your own species…).

[@wild_lee_coyote]

I once designed an alien species that was similar to the Velociraptor from Jurassic Park. But they communicated with color changing skin like a Cuttlefish. They have underdeveloped hearing since the planet had constant wind noise so sound is a poor form of communication.

This was exactly where my mind went first. PHM was a great example of the complexities of having two species with wildly different gravity and pressure needs. I also thought about how it affects the end. When researching my second novel, A Hardness of Minds, I found out that dolphins can hold and send a 'mental image', including translating images of object they've only seen into the sound of that image returned through sonar. So the aliens under the ice moon of Europa, and pass images around to each other naturally.

Moreover, vets pretty much only treat mamals and reptiles, a very small and closely related set of animals. Considering the huge proportion of genetic and metabolitic mechanisms we share with pretty much anything that lives on earth and the unlikelyness of an independant evolution taking the same root (I’m not saying they won’t necessarily don’t have the same basic building blocs, chemistery being the same everywhere, but for example, the way dna is translated to proteins is both almost universal on earth and apparently totally arbitrary), we can only imagine how different an actual alien would be.

You can get used to it. Then again not everyone could get used to wearing covid masks in the end, so I guess it depends on the person.

[@IffyJottere]

Early Star Trek handled the idea of different air requirements briefly with the Benzites in Star Trek TNG with the "inhalers" they wear on their chests. the Benzites were seen twice in TNG; Wesley's opponent in Starfleet Academy entrance exams in "Coming of age" and his brother Mendon who was an officer exchange candidate in "A matter of honor". As for medical supplies, that was addressed in TOS! In "Journey to Babel", when Ambassador Sarek was stabbed, McCoy tells us the ship hasn't got enough T- (that's T-negative) Vulcan blood in ship's supplies to do surgery to save his life. Spock has the same T- type, but only an experimental drug that amplifies blood cell production in Rigellians and other species similar to Vulcans gives him the ability to produce enough blood for the transfusions... at risk to his life at that.

[@Bearmauls]

Stargate SG-1 was a good illustration of the translation problem. They dealt with different languages frequently early on, but there's only so many times you can do that before it goes all the way from fascinating to annoying, so in the end they just went with everyone speaking English. Zootopia / Zootropolis does a rather nice job of showing many species of different sizes, shapes and environmental requirements living together.

[@tba113]

SG-1 and Atlantis also did a pretty solid job of addressing the medical side of things. It's made very clear that the Tau'ri have some of the best doctors in the business, and they have ready access to a ton of spectacular equipment, but Dr.s Fraser, Beckett, Lam, and Keller were straight up about how they're regularly reduced to just feeling their way through how a given nonhuman's biology works, by blind trial and error as often as not.

[@DomWeasel]

@@eskreskao The 'Enemy Mine' episode of season 7 was always one of my favourites for this reason.

Spoilers for Project Hail Mary: I loved that book because its clear Andy Weir considered each of these challenges when developing his alien life form and decided to set the bar at highest level of difficulty when solving for each, which makes their partnership/friendship feel all the more remarkable. The only real 'gimme' is that they both communicate at coincidentally similar vocal ranges which means that they can eventually talk and understand one another like Han and Chewie without Google translate.

The book discusses that - Rocky theorises that their hearing ranges overlap in the 'good for hearing danger' range of sounds made when things are banging together or a predator is approaching. And also notes that his own range of both hearing and vocalisation goes a lot higher that humans. Presumably he just speaks really deeply when using English.

Apparently the difficulty of communication between dissimilar species was one of the larger ideas in Knights of Sidonia (to the point of naming a place after Stanislaw Lem, who to my understanding really dug into that concept in his own works), though it wasn't very well displayed until the very end. While the series is very soft-scifi in many respects, it stands out to me in how it revels in displays of megastructural engineering. Other sci-fi has huge ships and stations, but none I've seen communicate that scale quite as well as the "Sights of Sidonia" and the shows of how such an environment is incredibly dangerous such as how most clothing is equipped with tethers to prepare for the often-deadly emergency burns.

The Temperature aspect does seem to be one good reason why Starfleet Crews tend to be predominantly of one species or another. An all-Vulcan crew's ship probably has an internal temperature closer to the warmth of Vulcan, while a crew of Andorians will prefer a colder atmosphere inside their ships. As Humans seem to be at a good middle-ground, it's likely the reason why Human-dominant crews see the most non-human members integrated into the crew, as they can tolerate middling Earth-range temperatures in most work areas, then adjust in their personal quarters, and still enjoy human visitors.

On the matter of language, In my homebrew setting, there is an empire with different species that can't make all the same sounds, and one octopus like race that communicates with patterns of colors instead of sound. The many languages were becoming an issue for a unified empire, so they created a language based on abstract units I call sylunits. Thus, each sylunit can have a different encoding for each race. Thus the majority of the language needs learned once, and then just learn each species' particular encoding. Thus one sylunit might be "cho" for humans, a short nasally bark for another, and a flash of blue and gold slanted straight stripes for the octopus people. Currently I am working on the actual conlang.

This is covered extensively in the Sector General series by James White. A multi-species hospital station in deep space. Environments from almost absolute zero and total darkness, to high gravity at temperatures that would boil iron. Medical knowledge is temporarily added to a doctor's memory with species specific tapes, but this does come with a price such as not being able to look at the food your eating or accidentally gaining a crush on a completely different species! One interesting thing is that all species have to use a four letter code to refer to themselves as automatic translation means that it doesn't matter what species a being is, they always refer to themselves as 'human'.

Its worldbuilding magnificence in relation to biological diversity, one I would recommend to any avid sci-fi reader... if you can stomach unpalatable amounts of sexism. I still recommend it, the sexism is of rather benign variety, "a product of its time" so to speak, it's just so rampantly present whenever the line between doctors and nurses is visible, it just sticks out by sheer amount, like a pound of salt in a gallon of broth. I find it ironic, almost to the point of this irony being the main take away from reading the series, how a person of such vivid imagination, imagination proven page by page, would be comfortable in assuming the structure of the human society would remain a carbon copy of early 20th century Earth. Hell, that's too generous of me - Earth as whole was a diverse place no matter which year in its history we make a freeze frame of. He just copied his own, quite narrow, social circles, and projected them not only on entire humanity of far future, but even many alien species. Just... how, man... how?

[@NimbleTack]

@@echinorlax It is something I noticed on later readings. I first came across the series when I was very young back in the eighties. Nowadays, looking back on it, the position of Murchison almost feels as if she's been lifted out of a Carry On film as a stereotypical nurse. I haven't read all the novels, but I believe that later she gets more agency as a full doctor. In that aspect it's an acquired taste, similar to Lovecraft where you have to get by his contempt of anyone who isn't "pure" bred. I do think that White comes from that era where science fiction writers were far more interested in the problem of their story rather than the characters. Clarke and especially Asimov seemed to love to use fiction to put forward a problem then have some clever solution put forward by a barely sketched out character.

[@vylbird8014]

The White Space novels have a very similar hospital - enough that I wonder if the author may have taken some inspiration from Sector General. The core hospital serves the entire galaxy, as a center for the most highly specialist care to which more generalised hospitals can refer patents with exceptionally rare or difficult conditions. Like Sector General it's a multi-species hospital partitioned into many parts of differing temperature, atmospheric mix and pressure. It's also spin-gravity, so the areas for low-gravity-adapted species are closer to the center and high-gravity on the rim. For part of the story there's a disruption to hospital systems that disables the lifts, so getting from one place to another often has to be done through several changes of environment suit and airlock.

Due to my scifi roots, I *love* including the language and biology challenges in my D&D games. Underground races that haven't seen the surface in hundreds of years? Why would they speak common? If they evolved underground, they don't even bother with light sources--they can see just find and their food is designed to grow in the dark. Going to the far north beyond the mountains? Completely separate language unlike anything the players have met, so a couple sessions just figuring out communication (when no one has Tongues or Comprehend Languages). It's one of my favorite curve-balls they don't expect. This video exemplifies why it's so much fun to throw such challenges at them.

[@GabrielGABFonseca]

I think some of my favourite examples of this come from the Official Traveller Universe. While most of the species in the Third Imperium are oxygen breathers, many breathe different proportions of oxygen, or need the presence of something that is a contaminant to humans, so Concentrator Masks, Filter Masks and Breathers are relatively common. There's also the matter of sizes; some Sophonts are tiny (a Llellewyloly is a ball about 0.5 meters in diameter standing on meter-long legs/arms) and humongous (a Virushi is an eight-limbed, quadrupedal rhinoceros-looking behemoth that weights a metric ton and stands 3 meters tall).

The crossover between different ability and disability is interesting. I remember the Green lantern story about Rot lop fan. He is inducted into the Green lantern corps but his species lives in darkness and his whole species is blind and their language doesn't include anything about either light or vision. Which means that the universal translator built into the Green lantern ring can't convey concepts like light and green and lantern. It becomes a complete lacuna for him, so they have to sort of translate the concept into sound, he's not a Green lantern, he's the f sharp bell, and although he makes the same kind of light constructs as everyone else, his brain interprets it all in the context of sound.

[@MagnusVictor2015]

I'll add another point (which usually comes up in softer sci-fi settings): what happens when two (or more!) alien species *look* fairly similar, but are quite different on the inside? E.g. consider so many of the different aliens shown in Star Trek: what happens to "bystander" first aid responses when someone would need actual training in order to tell several similar species apart? Is that person currently suffering a heart attack a Human, or a Vulcan? Is that person currently grabbing a piece of food from the serving tray a [Species_A] who can eat it just fine, or the similar-looking [Species_B] who will be poisoned by it (but might be new to the area and isn't aware). Etc., etc. Every year IRL, quite a large number of dogs and other pet animals die or are sickened by their loving human caretakers feeding them food (or providing other 'care' such as unusual exercise/lack thereof, nail 'trimming,' drinks, etc.) that is actually not healthy for them, and that's for species which we have evolved alongside for tens or hundreds of thousands of years! How common would it be for multiple aliens living alongside to genuinely make a mistake that harms/sickens a friend? (And the dark side: how easy would it be to cover up a murder when it's common enough to claim "I didn't know Centaurans were allergic to strawberries!")

One thing I used in a book I wrote set on a multi species space station was different species having different day lengths/sleeping patterns/regeneration cycles or whatever. Made it a real pain trying to arrange a meeting that wasn't in the middle of the "night" for someone.

[@DomWeasel]

I had fun with this in a fantasy setting with the human protagonists suffering with dwarven architecture (the ceilings are too low, the seats too low and the beds too small) and low lighting (subterranean dwellers can see better in the dark) as well as being told they speak too loud (hearing becomes more acute in darkness). Dwarves in turn take days to adapt to surface light and noise. When dealing with a species of elves, the humans struggle with their food which (as forest dwellers) is primarily fruit, fungi and nut based unlike the cereal grains (wheat, barley, rye, oats etc) which are the staple of the human diet grown in open plains. Elves live off the produce of orchards of trees; not fields of grass. And of course orcs eat a lot of meat. Too much meat for the human digestive tract to comfortably process. Because of their size and strength, orcs have to eat more food and more often than humans and they tire quicker; lacking human stamina.

[@reganator5000]

I've always thought of making elves obligate predators as part of the reason for their nebulously 'low population'. Like it's the easiest and cleanest way to make there actually be a clear reason that these nigh-immortal beings not able to not be able to get past the population problem over a certain period of time. Otherwise they stay identical, but their intrinsic desire for 'balance with nature' comes from the fact they don't have access to high calorie crops (though to note, this doesn't actually limit them to 'meat only' diets - it just means that they can't survive off grains like humans. Even cats eat vegetation, they just can't live without meat-derived-nutrients).

[@DomWeasel]

@@reganator5000 I always thought the immortal, low-population-growth aspect of elves was ridiculous. The result is either catastrophic over-population as every elf ever born doesn't die from natural causes, or they get into a war with a species that can replenish their losses in a generation and continue the war against an enemy that needs a 1000 years to recover from a single big battle. I gave them long life-spans, 500 years, and even that has many of the same problems. The Firire (Grey elves) in my story note that they still haven't recovered their numbers from the last war which at 500 years ago is a 2-3 generations for them. For the humans, 20-25 generations have been born since then. It's even worse for the longer lived race of elves that have 1000 year lives. The same Grey elf notes that between his grandfather and himself, humans have advanced from using bronze to steel.

[@commanderknight9314]

Uhm, a human could actually survive off of an entirely meat diet. A person would likely have to eat a larger variety of the animals parts than just the muscle tissue and some fat, but it is actually possible. It's a full vegan diet that a human can't survive on.

[@reganator5000]

@@commanderknight9314 you need quite a varied source of meat to do so - Narwhal is very important to most exclusively meat based diets today, though obviously in fantasy dragons, owlbears or giant spiders might fulfil a similar role. Though it's also worth remembering that most animals do not exclusively eat vegan or meat-only diets - they'll take what they can find. Cats must eat large quantities of meat to survive, but they still eat grass to help their digestion, and cows will happily stamp on small animals then eat them if they get too close.

[@DomWeasel]

​@@commanderknight9314 The human digestive system is designed for an omnivorous diet. We don't have the digestive tract capable of subsisting off meat alone. Animals that do are able to digest all parts of their prey; including bone and fur/hair. In order to live off a meat diet, you would to eat only certain cuts of meat meaning 90% of the animal would be discarded and you would still be dangerously low on fibre and chronically short of Vitamin C and E. This is why sailors in the Age of Sail living off salted/dried meat and ships biscuits died of scurvy. The carnivore diet is also lacking in salt which combined with the lack of Vitamin C would impair kidney function. Basically, you'd die with bleeding gums while pissing blood with the lack of Vitamin E leaving you too weak to stand.

[@patrickdusablon2789]

It's always been a major pet peeve of mine. How, in most mainstream sci-fi, all species eat the same stuff, get drunk or stoned the same way, all meds work the same, etc, unless there's a plot point requiring it to be otherwise. I love how this video takes it even further. One of my favourite examples of cross-species cohabitation is in the John Ringo/David Weber Prince Roger series. Our heroes are stranded on an alien world with a different biochemistry, and a very real concern they have is eventually dying from malnutrition due to some vitamins and amino acids not existing in the local biome. And at one point, our technologically advanced protagonists wind up being held hostage by a local low-tech potentate who tries to force them to cooperate by poisoning them with something that is tasteless and odourless to the locals and requires a steady supply of an antidote to be survivable, but to the humans it smells like sewage and tastes like rotten fennel, and it has absolutely no other effects on them. Another I really like is also by John Ringo in the Troy series. A human basically manages to uplift humanity to join the interstellar community by discovering that maple syrup has an effect more or less on par with a mix of tequila and cocaine on one alien species, and he sets up really lucrative trade with them.

[@vylbird8014]

I can think of three very different books that all come up with the same less-than-ideal solution: Take a cell sample and culture into meat paste in-vitro, to meet at least some of that nutritional requirement. One refers to the result as a "me-burger." The last one reminds me a bit of the Worldwar series too - among the many things which derails an attempted alien invasion of earth is the discovery that common ginger acts as a highly addictive drug best compared to cocaine. As the invaders long ago dealt with any dangerous recreational drug problems on their homeworld they have no knowledge of how to handle such a situation and much of their army is soon hooked on it. The human defenders are more than happy to manufacture it in great quantity and teach the lost arts of smuggling and dealing.

[@Belligerent_Herald]

There is one scene from the star fire series that I love, basically the carrier element of a multi species fleet got shot to hell, and as the birds are coming home controllers are scrambling not just to find bays for all the surviving fighters but bays on ships that can feed them and refill their environmental systems, assembling scratch squadrons based off of species that are physically capable of speaking the same language, because fighters are to small to carry translation software. There are scenarios where the pilots can understand the squadron leader just fine but are physically incapable of making the sounds to communicate back.

Conspicuous by its absence was any reference to the "Sector General" series of short stories, novellas and novels, by James White. The plots generally revolved around the difficulties of treating patients that are very alien. One of the short stories is the response to a mass casualty event at an interstellar spaceport when a large passenger vehicle crashes into a terminal, but the terminal and vehicle have mutually incompatible atmospheres. Chaos ensues, because nobody knows enough other species medicine to properly triage the injured, let alone treat them. This turns out to be the event that inspired the creation of the first multi-species hospital.

[@Treveli45]

Ian Douglas' Star Carrier series was good for multi-species groups. The antagonist Sh'daar are made up of lots of different species, from all range of homeworlds (and times). Three I remember clearly are- The 'diplomat traders', that refrain from eating in front of other races because they, well, vomit on their food before ingesting it. Think they were also the ones that talked by belching. One of the races spoke in pairs. They couldn't be translated at first because one of them would say one thing, the other something different. Then it was discovered when they talked together, their combined voices created a third harmonic that carried what they were actually trying to say. Another species, that used echolocation to 'see' and communicate, captured a human pilot, and were trying to learn about us and how to communicate. Their doctors couldn't figure out how humans generated or 'saw' sound like they did. The human's appendage on 'top' of their body clearly wasn't doing it, but they were curious if the fatty deposits on one side of the human's torso were their sound organs. (spoiler- the human was female) It was overall a good lesson on the problems of interspecies communication.

[@K_Cale]

Aye, love that series. Hard sci-fi with so many tech that are possible postulations of current ones!

[@tristanmitchell1242]

One Star Trek fanfic that I am reading currently actually deals with this slightly. While 90% of the Federation can handle O2/N2 atmospheres at 1 atmo pressure and around 70F temperature, some like Vulcans like it hotter and Betazoids like it colder. So you will often have a crew that is nearly or completely one species, so a Vulcan ship can be hotter and drier while a Betazoid ship can be colder and wetter. Human ships are notable for their mixed crews because they are basically smack in the middle of the usual range. That last 10% are those species that require vastly different food, atmosphere mix or pressure, and temperature requirements, and they ALSO get their own ships, and even their own Star Fleet Academy on a planet they can stand.

[@wrenchinator9715]

I have a (non-canon) Star Trek book about the TOS crew on their first adventure together. They established first contact with another alien race and beamed them aboard the ship, only to realize they weren't able to survive in the higher gravity on the ship. They had to beam them back real quick, and Mr. Spock accidentally got some of their personalities stuck in him when he unintentionally mind melded during the process. They were eventually able to host them on the Enterprise by reducing the gravity in specific areas, but not without Scotty spending several hours on it and covering Engineering with technical manuals and blueprints to figure out how. It was a fun book to read.

[@eskreskao]

There's a series of books about a space hospital called "Sector General", it's a mix of short stories and longer narratives. I might be misremembering, because it's been a good decade since I've read it, but one of those short stories focused on a wrecked ship found on the outskirts of charted space that had its discoverers baffled, since it didn't seem to make sense. One of those baffling aspects was a series of tubes running throughout the ship, each carrying a different gas, with vents in each cabin. The mysterious thing was, nobody could figure out why they were separated if they ended up going out through the same vents, and even more so since some of the gasses would cause some unfortunate reactions when mixed. In the end it turned out that each room got a different mix of gases to create a specific atmosphere because the ship was a space ambulance working for the uncharted space's equivalent of the titular hospital. The setting also had different stuff that covered multispecies habitation, like how everyone had a personal gravity generator - one of the recurring doctors was a giant mosquito-like creature that would've been squashed by the station's default gravity setting, so he had it set to like 0.25G, if not lower.

*Fun fact:* In the Star Wars universe, the closest thing to a civilization whose lack of multispecies is as high as on Earth is the archaic and isolated planet Kesh, inhabited for thousands of years only by the Keshiri species and a group of Sith humans who crashed on said planet. Something quite remarkable about this society is that, when the descendants of the Sith found a holographic projection of the Sith Pureblood Naga Sadow, many were horrified by the "out of the ordinary" appearance of that being, not being aware until that moment that there were more species in the universe apart from the humans and the Keshiri. I think it's a pretty accurate portrayal of how people of our World would react when meeting an alien by first time

One nice touch I thought is the Boron in the X series. They are aquatic, require water, their ships are filled with "air" (not necessarily oxygen) because air is lighter than water. Filling a ship with water would make it too heavy. Instead they have tiny chambers full of water and passageways. They use what is effectively space suits to go around their own ships with robotic arms and hands. Co-habitation with them on their own ship would almost be weird. As an Oxygen breather you would be restricted to other parts of the ship.

[@1FatLittleMonkey]

It doesn't make sense for an aquatic species to have artificial ship gravity. Without that, they could have _mostly_ air, but hypersaturated with enough moisture for their gills/etc to function (and not dry out.) No suits required. They'd only flood the ship when they are on planets and the mass doesn't matter. (And being aquatic, they'd presumably have ships that land on (or in) water.)

When humanity gained access to alien technology, our technology in regards to chemical engineering, metallurgy, space travel, weapons, etc. jumped forward by 1,000 years or more, but because medical technology and techniques couldn’t be transferred between species, it lagged.

[@Razalhague]

I think for a space station with many varied species, the best option would be a modular design. The main part of the station would be a mostly empty structure with docking interfaces that provide electricity, heat, coolant, and various common gases and liquids to isolated modules. Each species-specific module would use whichever resources it needs while handling uncommon needs on its own. Gravity could be handled by the module's position within the station's rotating frame. The station might even be able to host small to medium sized spacecraft as modules if they have a suitable interface and are a convenient shape. The station could contain facilities for synthesizing various molecules for medications, but I don't see a realistic way to provide multispecies healthcare beyond that. I think this would greatly simplify the station's design as it would mainly be concerned with structural integrity and managing the common resources. Any module would only need to sustain one type of environment, though I guess the station might have a small number of adjustable modules for rare visitors, emergencies, and acclimatization between environments. Common areas would be their own modules that are permanently tuned to a compromise suitable for some subset of station inhabitants, if such compromises are even possible. Modules could even be built or decommissioned as the station's demographics change over time. Transportation between modules would be its own challenge, but I think that's a lot easier to solve than building an entire monolithic station that needs to accomodate every species.

[@Marconius6]

Even with species that can mostly live in the same environment, there might be slight differences in preference, as Garak famously lamented.

The two classes find communication difficult, but have set up joint space stations with segregated living areas for the two classes. Within the oxygen breathers, the novels look at differing social structures and societal values, rather than any of the more practical elements, such as food. Still, they are an interesting attempt to address some of the challenges involved.
