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😅

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.

Its gets darker and darker and you lose sight of them but you're still able to communicate.

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.

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?

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.

The thinking and world views were so far apart that they just couldn't see each other as 'same'.

@@magnuslunzer2335 FYI, we never learned to “speak” with the other great apes either. Nearly every expert, that wasn’t attached to the projects, agrees that the gorillas and chimps that “learned” sign language didn’t learn sign language. They learned to mimic signs, but that’s it. 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.

@@Leto_0There's no air inside the skull to counteract the external pressure of the water, a reduction in the spermeceti's volume results in a void that simply collapses inwards. The soft tissues (i.e. skin and blubber) can sustain the deformation around the collapsing area if they're built for it. Imagine the experiment where you blow up a balloon inside another. Deflating the inside balloon (decreasing the melon's volume as it solidifies) will deflate the outer balloon as well, reducing its total volume as seen externally and of the displaced air (water).

A great video. We do have a better understanding about why these whales are able to dive so deep and how they’re internal organs function in order to dive as well to go back to the surface. 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.

@ArchTeryx00 Жыл бұрын

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!

Don’t count on that happening. Most experts think that it’s possible for certain cetaceans have a true language, buts also that it’s pretty unlikely. The other great apes (such as chimpanzees) do not have language (probably, it’s really difficult to prove a negative). 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.
