Octopus is a creature that lives on the bottom of the sea, but they are not fish, but mollusks. They have many special structures in their bodies, such as multiple memory systems, multiple hearts and so on. Another special structure is their tentacles. Octopus also has a nickname called "octopus", which is actually named after the number of tentacles, that is, they have eight tentacles. These tentacles usually have suckers, which can be easily observed.
As described above, octopus has eight tentacles. In addition, octopus tentacles are very important. Octopuses usually stay in one place on the bottom of the sea for a long time without moving their position. But when they want to move their position, tentacles can play a very important role. In addition, these tentacles can also play a role in protecting themselves. For example, when their tentacles are bitten by an enemy, they will break a tentacle directly, and then run away when the enemy is not prepared, and their tentacles can regenerate.
Moreover, when hunting, the role of tentacles is irreplaceable. Their tentacles are usually distributed with many suckers, sometimes the number of suckers will be 100 or even hundreds. Therefore, this makes their adsorption very strong. Researchers have done special studies on octopus tentacles and found that although their tentacles have adsorption effect, they do not suck into their own body. Such strong adsorption will only suck the prey quickly, and then these tentacles will wrap the prey tightly, so that the prey can not breathe, nor can it break free. So that the prey will soon be unable to breathe and die. The octopus eats its prey only after it has died.
