A group of marine ecologists from the University of Murdoch in Australia have been analyzing the behavior of dolphins on the west coast of their country for six years. They have discovered that when these seemingly calm animals want to feed on octopuses, they murder them in a rather cruel way.
The reason is that the octopus can be deadly if eaten shortly after this animal has died. Keep in mind that the nervous system of octopus is the same as ours, since cutting their tentacles are not cutting their link with the brain; Two-thirds of its neurons lie in its eight arms, and the octopus uses these neurons to try to escape its predators, even after it is dead.
In fact, it would not be the first time you see a dead dolphin trying to eat an octopus. Once he found a 1.3-meter dolphin that died with an octopus in his stomach, but with a tentacle coming out of his mouth; Another found a cephalopod literally hooked into his mouth.
So dolphins, one of the most intelligent animals on the planet, have been learning how to feed on octopuses without anything harmful happening to them. When they catch one, they have several ways to kill them and make them easier to digest them: they catch it with their teeth and jump on the surface of the water, to make them collide with the sea and tear them apart, or they come to the surface and shake the Octopus from one side to another, to achieve the same goal of being able to eat the octopus in smaller pieces.
