The youngest calves stay at the surface, mainly in warm water nurseries where killer whales are rare. Older members of the family often babysit with them, not just to defend against predators but also prevent them from getting lost. These babysitters include aunts and grandmothers, but also older subadult siblings. Also, new born sperm whales are still big animals, at 4 meters long few tropical marine predators would threaten it. The greater problem lies with the beaked whales, which mainly rely on being sneaky as their main defence against killer whales, and many live exclusively in cold waters with high killer whale density.

I think it would be cool if you did a vid on the evolution of these squids, although since there probably isn't very much information on these rarely seen creatures, a video on abyssal gigantism, or the tendecy for deep sea creatures to evolve to huge sizes, would be cool too :) keep up the great work !

In addition to the species mentioned in the video, there is another whale that feed on large deep sea squids. Killer whales are now know to be surprisingly competent deep divers, capable of reaching a depth of more than a 1000m. They also prey on squid more often than people realize: the transient killer whales of North Pacific rely heavily on squid to supplement their marine mammal diet, and those in Bremer Bay in southern Australia, famous for preying on blue whales and beaked whales, have also been observed feeding on giant squid. Interestingly, this means that killer whales are not only a potential predator of pilot whales, but also an important competitor. This might explain the antagonistic behaviour between the species, where pilot whales are often the aggressor. There is even one observation where a large group of long-fin pilot whales tried to rescue a strapped tooth beaked whale from killer whale attacks. Many beaked whales feed mainly on small fish and squid, and hence do not compete that much with pilot whales, who focus on larger prey.

Its like the situation in East Africa. Lions prefer wildebeests and zebras, but when those migrate, they have to be creative and get by with more tricky, more dangerous or just less profitable prey, things like warthogs, impalas, baboons and even elephants for instance.

Squid has been master of the deep sea long before mammals evolved. Molecular studies suggest that different deep sea lineages diverge from one another 100mya, in the mid Cretaceous.

Same here.

I have a hypothesis that the other reason they target deep-sea squid is they use the dramatic pressure change on the squid to kill it. Squid are very hardy and flexible; a predator would have trouble killing one by bite force or even by whole swallowing (and can you imagine a sperm whale forcing a live, fighting squid down its relatively small throat?). But to kill a deep-sea squid, a sperm whale just has to grab one at the bottom and swim to the surface, and let the barotrauma do the work.

Strange fact: there was once a very aggressive species of unknown whale, possibly a sperm whale or a very large orca which harassed and sank ships for over 50 years around the waters of the sixth century Byzantine Empire capital, Constantinople.

@@JohnyG29most likely no. Just looking at historical evidence, killer whales have rarely sunk or attacked ships. Only a handful of ships have been documented to have been sunk by orcas. Meanwhile, sperm whales have been recorded sinking ships for hundreds of years. One individual Mocha Dick, was famous for attacking ships and was thought to have sunk between 5-22 ships alone. Another incident was the sinking of the Essex where a bull sperm whale intentionally sank the ship. Furthermore, the whale polyphiros estimated size was well above what any orca has been recorded to grow to. It also hunted alone, a behaviour more typical of sperm whales. Polyphiros had extensive descriptions of its skin colour, dark purple. No mention of the tell tale white patches and no mention of the distinctive fin on orcas. Based on all the evidence it seems highly likely that this whale was a sperm whale. It’s also more typical behaviour of sperm whales to sink ships, a weird one at that. Sperm whales barely spend time at the surface and mainly live in the deep ocean. Yet many accounts exist of sperm whales battering and attacking ships intentionally. Weird when you consider that if any sperm whale feels threatened by a ship it can just dive so deep nothing can bother it. Sperm whales are odd in that they seem to hold grudges, waiting for and attacking human ships out of spite.

Large scale Iron oxide and rust was not common until oxygen was made more common by life for example. They might not go through the same kind of natural selection as life does but rocks do “evolve” after a fashion.
