How Dolphins Protect the U.S. Navy

[@joaoeduardoortega64]

The interaction between humans and dolphins is a really interesting topic to me. In Brazil, a group of dolphins developed a symbiotic relationship with fisherman with no training at all. The dolphins swim in a circular motion around the fisherman, forcing fish into the nets. The fisherman than reward the dolphins with some of the fish. But what is really fascinating is that this behavior is being spread across multiple generations of humans and dolphins.

[@ShneekeyTheLost]

This is similar to dolphin hunting habits out in the wild as well, where dolphins would move around a school of fish, compacting it into a 'bait ball' where they would then take turns feeding.

[@diakounknown1225]

I did not even know there was a difference. But in hindsight. Yes there definitely is.

[@jasonreed7522]

I just looked it up and it appears the 2 fundamental differences are that the reference level is different (decibels are 20log(x/xref)) with air being 20x the level used in water, and water having a higher impedance than air. Apparently a rough conversion is to subtract 62dB from the value in water. The reference value for air is based on human hearing (an inconsistent but understandable reference point) so I'm curious why the underwater reference point would be different?

[@CaseyConnor]

@@jasonreed7522 AFAIK the conversion of subtracting 61.5dB from the water value is to get an equivalent power-per-area of air decibels, but I'm not sure how well that equates to actual human perception (i.e. whether something 50dB-air sounds as loud as something 111.5dB in water). Regardless, I think the reason they don't reference the same pressure level is just because AFAIK water pressure dB aren't typically used to characterize perceived loudness but rather for engineering purposes (sonar, bathymetry, etc). It would be nice if there was a standardized conversion so you could say "the sperm whale issues calls as loud as an equivalent of 120dBA-SPL in air" but I don't know if the physics of sound perception underwater are even reliable enough ... maybe your bone structure, head size and density, whether you have little bubbles trapped in your ear canal, air trapped in your sinuses, etc, make it wildly variable? Or maybe you just subtract 61.5 and that's good enough?

That a few dolphins or belugas choose to quit their jobs and swim around freely (if that is what happened) is not necessarily a sign of bad treatment. These are individual animals. Like with humans, not all dolphins like the same things, so dissatisfaction by some does not automatically mean dissatisfaction by all or even most. The fact that they can just swim away when they are on a mission sounds like a good thing to me, and a sign that life with the Navy is at least alright for these animals.

[@davidreames8752]

You don't see to realize these AWOL animals escaping are wearing harnesses that will cause them to drown to death if they are entangled underwater. Those fishermen saved that Navy beluga whale's life by removing the harness. Animals in the military are enslaved and their lives are put at risk when deployed into war zone. They are not enlisted out of choice, they are enslaved.

It sounds just like having a job, do weird sometimes arbitrary/arcane tasks in exchange for food, shelter, medical care, and scheduled downtime. And since the dolphins can run away whenever they are on missions and instead (almost) always come back it sounds like they are not dissatisfied with their current employment. (More than most humans can say about their jobs)

[@AdleisioCefnforDolphin]

The one thing we need to be mindful of is anthropomorphism in saying that animals are "happy" is very limited in it's meaning because we cannot actively ask them and a direct yes or no answer, at least for now. Dolphins are near sapient, not just sentient, but sapient in how they behave and interact. There is to me at least sufficient evidence with how they will have regional dialects and can convey abstract thought information through vocal communication alone with each other. We should also be aware that even if the Navy leaves the pens open at night for them go out and socialize in a larger area, we feed them and give them shelter and safety from predation and other things would harm them in the wild. So it is not unreasonable that with their level of intelligence that they would naturally return to not have to deal with the constant need to hunt and monitor for predators and other threats. I have seen and heard of even wild caught captive snakes doing it, because most animals are smart enough to know when they have found a way to ensure safety and survival. I don't mind animals being used in the service of helping keep people safe and to do their jobs, but also need to being mindful to not use them for actively harming other people, we should never use them to fight our battles. I think it would be more useful to pour money into research and develop into a sonar system that could work just as well as a dolphins so that we wouldn't have to use them much how vehicles replaces horses when it comes to people fighting wars. The other thing to consider though is that Navy sonar can and does disrupt wild populations of dolphins and other marine life to a very significant degree, and in some cases actually deafens individual members and groups. Being dolphins are far more sensitive to their environment, and humans are one of the most disruptive forces to have ever existed.

[@death13a]

I never really like how people assign regular working animals things like happiness and imprisonment. Dolphins can make up there own mind if they want to stay or swim away. Now I don't support any animal training that humans won't do. If you ask animal to risk it's life then you better be able to do the same. Also I think employment of marine animals is underutilized. Dogs have all kinds of jobs, marine animals can save many lifes like have Dolphins patrol beaches and help save drowning people as dolphin can reach person way faster then life guard or train them to find resent sunken ships/airplane. Heck you probably could train some species of sharks to find objects/people. Animals have so much more to offer in cooperation with humans.

Great video. I was a Navy EOD Tech and worked with sea lions and dolphins. We didn't dive with the sea lions, but the dolphins on the west coast were a trip to dive with. 400 pound animal turns at you from 100 yards and comes right at you in a couple seconds then bends away at the last because you gave him a bad spot on his last dive marking a target. No more thumds down after that.

[@ACAB.forcutie]

I think all if not most working animals want to be working. They might quit later or retire earlier than us humans were planning, but I do believe they wanted to and found it rewarding. When selecting animals to start training, there are certain characteristics that you look for. As you start training, lots (if not most) of them "fail" and go on to live whatever life they would have had. Either they lose interest in their training, something happens, I even saw one dog training to be a police dog that "failed" because they were too friendly so they lived their days as a regular pet. My own service dog basically made it clear she only wanted to work part time but that she would be there for me. Working animals handlers HAVE to be so in sync with their animals that they understand them, and animals that are smart enough to be trained to work are smart enough to learn to communicate with you, in their own way. There is a huge amount of mutual respect by necessity and by nature. I heard a story about a drug dog at the airport, apparently he alerted at pizza, and his handler went "yeah buddy, I know pizza confuses you" and rewarded him anyway. I let my dog do pretty much what she wants, but she knows when I'm being serious. Working animals are absolutely amazing

We can atleast do some basic sign language, granted they are limited in their ability to make signs back at us do to their lack of hands. While it would be awesome to have a vocalization to vocalization translator (like the universal translator in star trek) this assumes that: 1. They have a genuine language. 2. Our 2 languages share concepts that can be translated between. (Concepts like fish, food, water, self, other, math, grammar, death) 3. Neither language is too complex for the other species to grasp. 4. That dolphins actually want to talk back to us. This isn't to say its impossible, various animal species have complex communications, shown emotions (including grief, spite, and trolling), and some captive primates can be taught sign language. (With 1 gorilla who's name i forgot signing the word "sad" over and over as it grieved the loss of its child)

Dolphins and porpoises have a history of helping humans, all without "training" or any obvious incentives.

Lets face it, if the dolphins decided they didn't like their work, they would just fuck right off with the equipment once in open water. They're smart enough to determine whether or not the mutual benefit is good enough to comply or not. Dolphins are extremely intelligent animals, Orca's probably being the best example of this as they have the capability to recognize themselves in mirrors and form their own cultures and languages. Dolphins have also been known to develop symbiotic relationships with fishermen of their own according, forming a mutually beneficial relationship for both parties that continues over generations. Something that was explained in more detail by another commenter. These are highly intelligent animals, rivaling humans in many ways so being able to engage in the kind of work they're trained for might actually be enjoyable and enriching for these animals. It's nothing like being stuck in enclosures at zoos and aquariums. These animals get to experience open water and constant enrichment as they work.

@@protoretro1290 Conventions are different to peace treaties. Many arms reductions and treaties on the laws of war have been enacted and well followed. In fact the treaty on the prohibition of chemical warfare is a spectacular example of it, after ww1 it was agreed that chemical weapons lead simply to mass casualties for no discernible gain, and so it was agreed no parties would use it, as a result nazi germany nor the allies deployed chemical weaponry in the battlefield, as result millions were saved from death and disfigurement that would have befallen them under ww1 conditions.

I don't think anyone that hasn't worked with an animal can say if it's content or not. There is happiness in nature. It's either content and joy or pain and suffering. Those dolphins and sea lions have the opportunity to leave unlike some other animals. They are let free. I see them as i see falcons and falconers. They know how to hunt. They know how to fly. They can leave and some do but many return. It's this deep connection between trainer and their animal. A partnership. It's often ppl say working dogs are imprisoned or unhappy and while some have issues related tp the job they did many of them enjoy it and often miss it. The dolphins are sentient enough to see mutual benefit. They choose not to leave when they have the opportunity. Yea some leave vut some dogs run away from home too. Doesn't mean all dogs are suffering as pets. It's antromorphisation to say an animal is happy or unhappy as an outside viewer. It's trough the animals action and behaviour we judge their mentality. No abused animal will come back to the abuser. Expecially one of high intelligence. They are trusted enough to do a work consistently which tells me they find what they do meaningful. There is nothing more to life than that. They are not "unhappy" therefore they are content and "happy". What is the difference between training those and a falcon? Or a dog? Or a horse? They all do wht we ask them because we took the time to make the animal understand and connect to it. We make the animal care fpr our satisfaction. I ride horses. If i miss days because of weather they get agitated. They can go out. They can run as much as they want. Yet they are annoying they don't go out on rides. Although they know i will be on their back. They will have reigns and saddles that they will maybe see scary things. They let me ride them because we build trust. Trust that i will protect them and they will be safe. I see no difference between that and the dolphins and their marine officers. Or a police dog and it's handler. It's about trust. The trust the animal gives us of being safe and rewarded. And our trust in it of doing it's job

They were forced into military service for wars of another species and can die when deployed into a war zone.

Dolphins are perfectly capable of choosing to work with humans because its a net benefit for the animal.

When a conflict comes every marine mammal can be suspected of being a trained operative and killed out of precaution. So that is the moral trouble of militarizing animals.

Like a drug dealer paying a 11 year old child 20 dollars to make a dangerous delivery for them so they thermselves do not risk harm. Is that moral? How is feeding an animal to perform war duties any different? It wants food and doesnt understand the larger perspective or consequences, so accepts the reward gladly. Like the child delivering drugs for the gangs.

Obviously the russians use belugas because they are arctic adapted and just as smart, for their ambitions there. Its sick.

Note the dolphin jumping ahead of the sub at 6:47!

[@chaseassaker7227]

This is literally the coolest video I have ever seen

[@FutureAIDev2015]

The dolphin at 13:40 certainly seemed to enjoy its job and the trainer 😊

Glad to discover this Chanel

correction: high frequency means higher energy. very interesting video.

[@reflect7559]

Sorry for deleting the first comment, but I did a little more research and I think I see where the confusion is. In the electromagnetic spectrum, a higher frequency always equals higher energy (at least I'm not aware of any exceptions). However in acoustics the level of energy is represented as amplitude, not frequency. Instead, frequency represents the pitch. That said, in a situation with two acoustic signals of the same amplitude with different frequencies, the higher frequency signal will have more energy. So the total energy of the signal is kind of a sum of the two parameters. So really it depends on what the submarine in question is capable of, and what it's objective is. If a sub isn't trying to be particularly stealthy, they are probably going to be using sonar instead of radar.

[@varunsa7047]

@@reflect7559 actually sound waves (and other longitudinal waves) have pressure amplitude directly proportional to frequency. P=(2(pi)BSf)/v , where 'P' is pressure amplitude of sound wave, 'B' is bulk modulus of fluid, 'S' is particle displacement amplitude, 'v' is propagation velocity of sound wave in the fluid, and 'f' is the frequency of sound wave. So if the frequency increases the amplitude also increases, they are interrelated and not two separate parameters.

[@varunsa7047]

@@reflect7559 Also RADAR cannot be used underwater as the EMW of even longer wavelengths (like microwaves) are easily absorbed or scattered within very short distances. Which is why SONAR is always used underwater (and in other high density fluids, for example getting image of organs, fetus in pregnant woman etc.)

[@reflect7559]

I learned something new today. Thanks! I'm an audio engineer and producer, so in my practical experience the two have always been separated. Brief research probably wasn't going to fix that misunderstanding. Its interesting and useful to know how interconnected they really are! Also thanks for the nifty formula. Always handy to have maths like that in your toolbelt

[@varunsa7047]

@@reflect7559 no problem man. Coincidentally I was studying the sound waves chapter in physics at the same time this video was released. Audio engineer and producer is a cool job! You probably know more about sound intuitively than I do lol.

So your telling me I should expect 4 penguins from Madagascar to be real?

I signed up for nebula and curiosity stream. Excellent content but the web player and android app for nebula are terrible. They are buggy and the app has no speed control.

you know what the dolphins are thinking? "so long and thanks for all the fish"

1:50 the whale bite the seagull is so cute!

Imagine being a Vietcong commando and the last thing you see is a dolphin charging at you.

dear diary, my depression grows deeper as i find my self more useless than a semi aquatic marine mammal

[@zakriarahimi4951]

thanks you for the video

[@SimonNZ6969]

That Seagull though. Its like a mildly annoyed friend. I think the reality is at the moment, these animals save lives. So their use is necessary. If you truly want to help them and people, you should be supporting efforts to replace them with technology. It's the same with Veganism. Don't just tell people to stop eating meat, they'll never work. Encourage the development of alternatives, virto meat/plant-based etc. You'll never change a person's mind by calling them a monster,

The navy even trained Seals to fly in helicopters and shoot guns. A heard a pack of those even took out Bin Laden

5:26 From this point on, the background music has an extremely annoying volume oscillation. Maybe it has something to do with my misophonia, but that oscillation has made it impossible for me to keep watching this video :-(

[@Zupiter8]

its cool and all but its a pretty obvious answer - nothing wants to live in a cage for any amount of time. you'll notice the dolphin at the end has a messed up snout. this is likely from ramming its face into a cage.

[@billy-xx3gh]

Man is the smartest animal ever Dolphin let's you do all the work, build boats, docks, ports, harbors, maintain the boats, build equipment, get a crew, risk nature all for a couple fish. Dolphin goes "eeeeee" Gets fed. Who is playing who lmao

[@Jr_Scientist]

establishing their dominance in the marine domain.

[@Rapidly_]

Yeah replying to animal abuse accusations with "it's important for the lives of American citizens" is really bad. And following that up with "they're untethered in the open ocean, they could leave if they're unhappy" is REALLY BAD. Abuse 101: victims can't leave. More often than not, abused humans stay with their abusers, abused dogs don't bite their abusive owners or run away, why wouldn't that be the case with abused dolphins too? NEVER use "if they were unhappy they would leave" as proof of abuse. It's an incredibly dumb statement.

[@adampetten1009]

Beluga whales are unbelievably tame, we've seen them lots off of newfoundland and they are very playful and enjoy following boats

[@ilovetolearn999]

Just a friendly correction for 6:11: Actually,high frequency waves have more energy than low frequency,its more condensed.

[@PossumKommander]

The idea of navy seals deploying with actual seals is a movie I want to watch.

[@Gkitchens1]

Sailor: Okay we're gonna have the dolphin use it's sonar to- Dolphin: Excuse me we call it echolocation Sailor: Dolphin: Also we want the same pay as the seals, I heard through the water one they took out that terrorist, we saved your ship Sailor: They can talk Dolphin: Oh crap I mean *squeeeeeak*
