The average life span of octopus is generally around 3 years old. If the living conditions are ideal, you can live to be about 4 years old at most. Octopus has developed eyes, which is the only similarity with humans, but it is very different from humans in other respects-octopus has three hearts and two memory systems: one is the brain memory system, and the other is directly connected to the sucker.
Small octopus can learn the skills it should have in a short time; Unlike most animals, the learning of small octopus is not based on the teaching of elders. Little octopus learns to hunt, disguise and find a better place to live alone.
Octopus behavior
Octopus sucks water into the mantle, breathes it and excretes it through a short funnel-shaped tube. Octopus mostly crawls on the seabed with suction cups, but when it is frightened, it will spray water from the body tube, and the sprayed water flow is strong, thus moving quickly in the opposite direction. In case of danger, ink-like substances will be sprayed out as a smoke screen. Some substances can paralyze the attacker's sensory organs.
In order to avoid being killed by predators, octopus not only uses the well-known mimicry camouflage and wrist guard technology, but also bends and folds six of its eight claws upward to make coconut shells when facing danger or encountering divers, while the remaining two claws will stand on the seabed ground and secretly move backwards, just like a small moving coconut, so as to retreat. Walking with two brachiopods is much faster than walking with eight brachiopods. The fastest speed of the former is about 0. 14m per second.
