When it comes to octopus, the first reaction of many friends is the fried octopus on the barbecue stall. It tastes fragrant, soft and crisp, and is very popular with people. In a word, for people who like to eat octopus, mollusks like octopus are the most likely to become food in people's mouths. Then we should all know that octopus belongs to the bottom of the sea, right What is its living environment under the sea? Let's take a look together.

Octopus is short oval and has no fins. It is mainly a temperate mollusk. The food it usually eats is mainly plankton, and it basically hides in caves or rock crevices on the seabed. It especially likes to hide and doesn't like to swim out. It is basically distributed in various oceans and caves in temperate regions.

Because octopus is a temperate creature, it lives in normal temperature water all the year round, and the most suitable water temperature should be no less than 7 degrees Celsius, and the most suitable seawater ratio is 1.02 1. Octopus can't live in low temperature water environment, because the environment with low salt content will make it unbearable and eventually lead to death. In other words, the sediments in the sea where octopus lives are preferably gravel belts. When the water temperature reaches 12℃, can pomfret lay eggs smoothly? .

Although we think octopus is a mollusk, many people can't imagine that octopus is actually a carnivore. It mainly eats plankton, shrimps and crabs. Why do octopus eat meat? In fact, it is to stabilize its own structure myoglobin. It is necessary for octopus to survive in the deep sea. Therefore, octopus usually likes to lie in the sand at the bottom of the sea, wrap shrimp or crab directly with their claws when they are not looking, and then enjoy it.

When the octopus is in danger, it will use the powerful jet water to move quickly in the opposite direction. When the danger involves his own life, the octopus will spray ink-like substances as a smoke screen to protect himself from escaping. This smoke can paralyze the attacker's sensory organs and make him lose consciousness. ?
