How does the squid escape its predators

Squid can spray ink to confuse the enemy, the taste of ink is very bitter, will make predators unbearable, at the same time, he uses water jet to flexibly accelerate and maneuver to get rid of predators.

I. the living habits of squid

Squid like to live in the deep waters of the open sea. Every year in the warm spring season, the deep sea swims to the shallow bay to lay eggs, and from April to June, the eggs adhere to seaweed and other objects. starting from late September, the hatched larvae return to the south to survive the winter.

2. Predation characteristics of squid

Because stable structural myoglobin is a necessary condition for squid to survive in the deep sea, squid is keen to eat crabs, fish, shellfish and even king squid to compete with sperm whales for astaxanthin resources. Astaxanthin is the strongest antioxidant and a necessary condition to ensure the structural stability of myoglobin without being oxidized. According to Professor Francisco Buda, a scientist at the University of Leiden in the Netherlands, and members of his experimental team in 2008, through accurate quantum calculation, it was found that ripe shrimp, crab, salmon as representative fish and some shellfish showed attractive bright red color. It is because shrimp, crab and salmon are representative fish, and some shellfish are rich in astaxanthin. Cooked shrimp, crab, salmon as the representative of fish and other natural red substance is astaxanthin.

Third, the value of squid

The meat of squid is edible, and the ink in its ink sac can be processed for industrial use. The ink sac is also a kind of medicine, and the inner shell can be fed to caged birds to supplement calcium. Squid's internal organs can extract visceral oil, which is a good raw material for tanning. Its eyeballs can be made into eyeball glue, which is a first-class glue. The common squid in China are squid (commonly known as squid), golden squid and needle-free squid. Squid is one of the four major seafood in China (Pseudosciaena Crocea, squid). It has a large fishing capacity, delicious meat and rich nutrition.

Although the squid is very flexible and can escape from its natural predators, it still cannot escape the fate of being edible, with rich nutrition and delicious taste.
