    I don't know why, but the idea of making a Rosetta Stone for the sperm whale's language really hits me in the feels. For so long, humans have been wondering if we are alone in the universe and spent so much time looking into space to try and find neighbors, when in reality we should have been looking into the oceans. Sperm whales and orca both have complex languages, and I wouldn't be one bit surprised if we found out one or both are sapient, and sentient, creatures. I honestly can't wait for this teased video.

This is something which, to the best of my knowledge, is NOT something science has proven yet.

    No a whale does not have a language even close to our language. Our language allows us to transfer knowledge across multiple generations to increase our knowledge and allow us to build and innovate. A whale has sounds that have as many words as we have numbers. We have an infinite number of numbers and a unique set of words for each number, so the whales are probably just calling out where they are. Whales cannot innovate and do not know anything that their grandparents knew, so they have no real language.

    The bit about whales possibly learning and conveying strategies for evading whalers is extremely interesting. I also wonder if the intelligence of the sperm whale and the intelligence of the squid came as a result of an arms race with each other. If so, sperm whale intelligence appear to have evolved more in the direction of human intelligence; where we evolved abilities to communicate and organize and take advantage of collective intelligence. By contrast the squid, who's a solitary animal, evolved incredible spatial intelligence and abilities to solve complex cognitively demanding tasks.

    I wouldnt parallel evolution with the human arms race. Sperm whales are situated in the position of predator in this situation by default due to thier biology the advanced communication isnt needed to help them hunt, as far as I can tell they do just fine solo although communication may be useful to relay where there are alot if prey. Also, the ease with which they hunt (probably by stunning thier prey with sonar, makes it seem to almost not even feel as much like hunting.. more like.. grazing😅

Your pod tells you that its time to go deep into the dark abyss to hunt. Your heart starts beating faster and faster as you dive deep and the only comfort you have is your pod of whales. Its gets darker and darker and you lose sight of them but you're still able to communicate. You gain immense respect for whales but also wish you can return to being a human, as the cold dark Abyss terrifies you. You wake up and let out a sigh of relief. Your mom comes in the room but her head is a whale, so you go back to sleep.

If we can understand the simple, and the complex it would be something...but we don't understand "simple" communication, so perhaps communication is more instinctive than complex. We understand humans because we are doing a human thing. Squid communicate and understand light/color, which is complex but instinctive to them. (Some European thought saw language as a divine gift, like a skill, rather than something we do on instinct. IF I'm right, language is complex but hard to interpret for non-human minds...like try describing music or sound to a deaf person, or color to a blind human? How would a squid communicate a magnetic field to a human using chromatophores?) Sorry for the nerd philosophy :p (it's a fun topic to hypothesize over)

    The mathematics of multi-path sonar are incredibly complex. How these animals can determine the direction of a whale cry, over bundreds of miles distance, has always been fascinating to me. Sonar waves can bounce not only off the ocean floor (obviously) but also the ocean surface and even get trapped in "water tunnels" created by differing water temperatures and salinity. The maths to calculate these things, for example on nuclear-powered subs, are some of our most highly-classified military secrets. So how do these whales do it? Are they effectively solving complex trigonometric equations in their head?

Even as interaction between different human cultures, as much as we have in common, were not understood by the various parties. Take Europeans and Native Americans for instance. The thinking and world views were so far apart that they just couldn't see each other as 'same'. So to grasp some understanding of the inner workings of the brain of another creature entirely would be exceptionally challenging. Good luck with the project though.

    I used to work on a fishing boat in an area that had sperm whales. Tourist boats that went out to see the whales always came over to our boat when were were dropping (or pulling up ) our nets (set at 400 fathoms).I used to wonder why they did that - until I heard a recording of a sperm whale search/hunting clicks. Our net roller had a lump of weld on it and it clicked every time it went around - at the same spacing as the whale recording. We thought it was hilarious - the tourist operators never did work it out. I think the whales had a good laugh about it as well- as they were pretty chill around our boat.

    You’ve got a fundamental misunderstanding of nitrogen narcosis. It’s from breathing PRESSURIZED air. If you’re not breathing pressurized air (or gas mixes), the amount of nitrogen in your body remains the same and only the nitrogen in the lungs can be absorbed. The bubbles they found in them was caused by the volume of the Navy sonar, which can boil water with their sound volume.

Are all the vocalizations measures around the same decibel level or do they vary in range? Why are the vocalizations so loud? Does it allow for information/communication to be carried over a longer distance? Like if mum were communication with her calf not to follow as she dives deep.

It is true that quick ascending can cause a great deal of harm to these creatures as well as humans. Sonar exercises do have lots of consequences on whales death. The echolocation sounds are disturbing to human ear but it is the way they communicate. Indeed they are very social groups. When adults male leave their pod they get together with other males to explore, get mature and for breeding.

    Depending on their hunting "grounds", sperm whales have adopted different hunting techniques: a study has confirmed that, for example, whales in the arctic sea actively chase their prey, emitting extremely fast sequences of clicks once they're close to the prey and they usually dive 400 to 600 meters. They're really fascinating creatures and I can't wait for new discoveries on their lifestyle and complex communication!

Now don’t get me wrong that’s still impressive, but it’s not language. Basically, the only candidates left for a species besides us having a language are a couple of cetaceans and (if I remember correctly) a species of corvids. But even those are generally considered to be, “maybe, but probably not.” The reason we are (edit: are not as quick) as quick to say they don’t have language is because they are so dissimilar to us that their language may be much harder to detect.

If they had the ability to have a true language then they should be able to understand sign language. But basically every expert that wasn’t involved in the sign language projects agree that those animals didn’t learn sign language. Instead they think that they learned to mimic sign language, but could never use it in a novel or general manner.

    @@infinitemonkey917 I think there's quite a lot about human anatomy that is fascinating or remarkable it's just not as noticeable to most of us since we are ourselves humans so we sorta just take it for granted and think of ourselves as basic or "normal" (not to say that we are any more special than other animals ofc)

    Deep in the darkest depths of the ocean, where no light shines and most animals have never experienced light. *shines a giant flashlight down there*

    One of the examples of how sperm whale pods can closely coordinate is also fairly gross if you're not used to studying the animals. One of the key defenses a pod has against intruders is to basically all let their bowels go *at the same time,* releasing a giant cloud of... poop. And once caught up in it you aren't getting out without getting thoroughly messed up, by which time the whales have all booked it for the deep. There's footage out there of divers studying the whale pods that found out about this defensive behavior the hard way. So that raises the question: How do they coordinate that basic bodily function so closely? This video offers a tantalizing possibility: They *verbally* coordinate. They tell one another something's in the neighborhood that shouldn't be, ready a simple escape plan, and a click from whoever the matriarch is sets them all off at once. Great way of fending off sharks, orcas, or anything else that might be targeting their calves/smaller podmates/sick podmates/etc. And all done verbally!

    You should do one on what we know of Giant Squid and their other favoured prey, Colossal Squid.

    Whales sleeping like that is so eerie, can you imagine swimming among them when they're like that?

    I think another thing that's super interesting about sperm whales is their ancestors. Currently, sperm whales are unique. There aren't other predatory whales like them. But in the past the ocean was filled with whales like sperm whales, which I think is super cool.

    Dolphins, porpoises, and beaked whales are also toothed whales. Sperm whales are just the biggest ones
