Lacrymaria: Vicious Long-Necked Predators

[@journeytomicro]

Apologies for the weird dip in audio quality that happens for several seconds around 3:08. We tried fixing the audio a few different ways and it just wasn't working out, unfortunately. There are captions available if that section is too hard to understand.

[@DieFlabbergast]

Or maybe Loch Ness is actually a VERY small lake? The Scots are prone to exaggeration, you know?

[@sinait8191]

Imagine if giraffes actually behaved like Lacrymaria. You're visiting the savanna, there are pieces of animal gore everywhere and suddenly a Giraffe whips it's neck between trees, bushes and rocks to eat a hippo or lion alive by swallowing it whole, it's neck stretching like a sock around the animal as it struggles to escape. I'd like to see Junji Ito make a story about that.

[@kevinlatini9242]

Hey james, thanks for your amazing work! Quick question: In this footage they seem to not attack and try to eat each other, is this an actual thing in their behaviour or this "sociality" is just random luck because they're not able to actually see/sense each other?

@@Ezekiel_Allium She sells seashells by the seashore That tribute to Mary Anning, the discoverer of plesiosaurs, was written before this tribute (1908 vs. 1911). But when checking the dates, I discovered that _Lacrimaria Olor_ was first described in 1786 by Müller.

[@Bluecho4]

Lately, I've been contemplating the idea of a D&D campaign set underwater, with all amphibious player characters. Watching this video, it occurs to me that populating the oceans with giant bacteria - macro-micro-organisms, if you will - would be an interesting way to add variety to the campaign. As well as danger. A Lacrymaria the size of a horse would be a frightening thing to face. Its "neck" extending and coiling around corners up to 100 feet away. Probing coral reefs, sargassum clumps, or the halls of some sunken dungeon. Its attacking poisoning and grappling PCs, and trying to drag them back to be enveloped and digested.

[@Norwyn]

You could also think about shrinking the characters. An adventure in a drip of water with playable water bears and rotifers and "giant" plankton bosses would also be interesting. Or do both ^^

[@SauqinaR]

Omg. This is lit

[@dismae_]

I was having similar thoughts for an underdark encounter, or perhaps a swamp creature of some kind

[@druid_zephyrus]

[@michaelbuckers]

And this thing is unicellular, meaning not only does it not have any muscles to move around and attack prey, but also no nerve cells to coordinate the motion.

Great example of how evolution rarely invents new things. Most things an animal cell can do are just specializations of something microbes already figured out.

[@ameunier41]

@@LimeyLassen Don't forget the unicellular stage lasted 2.5 billion years, multicellular appeared 1.5 Billion years ago. The basic of life were well established when the first animal appeared.

[@MalcolmCooks]

imagine a macro-sized animal using lacrymaria's hunting method though a long tounge or tentacle that probes the forest floor looking for prey to ensare and drag back to the main nody of the aninal

[@netsch20]

I mean about as close as I can think is an anteater, and to a lesser extent chameleons. And in a way I guess you could say snakes? So I'd say if you take the long tongue hunting method of an anteater but made the tongue a 10 foot long snake that could eat it's prey whole, as lacrymaria and snakes can do, then you'd have it!

[@GLaDTheresCake]

@@netsch20 The first thing I thought about seeing the lacrymaria was a cone snail. They also use a tube shaped protrusion, and use it to inject venom from it after finding a target. Maybe not a vertebrate, but it's definitely a macro sized animal with a very similar method of predation (and defense).

How fascinating and beautiful. I hope the videos stay up, and maybe sometime in the future, it will be the right time to reinvest in this idea.

[@6Twisted]

What amazes me most about microbes is how they're able to move and hunt for food with no brain and relatively simple bodies. This Lacrymaria with no brain is able to randomly hunt for food, has a sense of time and knows when to rest and when to hunt.

I cannot imagine anything more terrifying than the concept at 4:37 - a predatory megafauna with no prey selection, no persistence but high efficiency; where no matter how quickly you move, how little noise you make, you stand just as much chance as any other living thing around you at any given moment of a gigantic neck whipping out from god knows where, taking a bite out of somewhere, anywhere, on your body, and then just leaving you, bleeding and helpless, for scavenger species to finish off. Absolute nightmare fuel. But, probably also driving a healthy ecosystem.

I was watching an amoeba eat a paramecium almost as large as itself in biology class in college when I noticed the paramecium developing cracks in its outer membrane. Shortly thereafter the amoeba stopped moving and began to rupture and release grainy fluids. When I was sure they were both dead I asked the instructor what was going on. He asked how long I'd been looking at the same slisde and I said ten or fifteen minutes. He said "When they do that, it means they're done." As in "The food is done." The slide got so hot under the lamp that it cooked them both.

In many countries voting isn’t mandatory and so there is the chance that many citizens don’t have the chance or the information to make their voices heard. Participating in the vote is taking active part in the government of your country. Don’t forget a lot of good men and women have given their life in the past so each of us can now make our voice heard. Vote, it’s your right.

This goes a long way to illustrate the universal "Principle of Correspondence" which means that what happens on a large scale happens on a small scale and vice versa. Just like animals have to feed, rest, multiply and they have special organs for each of these, so do these small single-cell "organisms", just at a smaller scale.

[@dragonwithamonocle]

When you said "wanton path of death and carnage" I didn't see it at first. My eye is untrained. However, the more I saw this lacrymaria in wide angle (ha. ha.) shots, the more I realized that wasn't debris scattered around it. That's dozens of tiny corpses. Husks of tiny organisms that have been drained. Oh noooooo... This thing just sort of forms a bubble of pure death around it, and everything that it touches skitters away at 110% top speed so you KNOW it's a bad one.
