How long is the life span of octopus?

Octopus belongs to the genus Octopus of the family Octopus. Octopus is called "octopus" because it has eight wrists on its head, and there are membranes connected between the wrists, and there are two rows of suckers without handles on the wrists. There are about 650 species of octopus in the world, which vary greatly in size. Let's take a look at how long the octopus lives.

How long is the life span of octopus?

The average life span of an octopus is only about 3 years. If the living conditions are very ideal and do not get caught, the octopus can live to about 4 years old at most. The lifespan of the deep-sea giant octopus is different. Some scientists say that the deep-sea giant octopus can live for up to 100 years, and its hatching time is as long as four and a half years. So far, the largest octopus tentacles have been found to be about 10 meters long. Biological experts say there may be octopuses of more than 15 meters (tentacle length) in the depths of the ocean.

What kind of food does octopus eat?

Octopus is a carnivorous marine mollusk, feeding on branchial and crustaceans (shrimp, crab, etc.), and some species feed on plankton. This is not a question of whether it likes it or not, because stable structural myoglobin is a necessary condition for octopus to survive in the deep sea. Giant octopuses do not hesitate to fight to the death with sperm whales for astaxanthin resources. Astaxanthin is the strongest antioxidant and is a necessary condition to ensure the structural stability of myoglobin without being oxidized.

Octopus has a high IQ?

Octopus has the ability of "conceptual thinking" and the ability to solve complex problems on its own, which gives it the ability to walk on two feet. After further research, scientists also found that octopuses live alone from birth, and that small octopuses can learn their skills in a very short time, and unlike most animals, learning is not based on the teaching of their elders. although their parents have inherited some abilities to them, small octopuses develop their ability to solve new problems by learning to hunt, disguise and find a better place to live. At the same time, the eight-legged species was able to move the coconut shell and use it as its own armor, the first case of invertebrates using tools.

Octopus self-protection ability

The octopus sucks water into the outer membrane and expels it through a short funnel-shaped body tube after breathing. Most octopuses crawl along the sea floor with suckers, but when they are frightened, they squirt water from the body tube with strong hydraulic power, which quickly moves in the opposite direction. Ink-like substances will be emitted in the event of danger as a smokescreen. Some kinds of substances can paralyze the attackers' sensory organs. In order to avoid being hunted by predators, in addition to using the well-known mimicry camouflage and wrist protection techniques, US scientists have also found a "high intelligence" octopus that can walk on two feet to escape in the Indian Ocean.
