is a kind of animal living in the ocean, and its distribution in the world's sea areas is very wide. Squid has many natural enemies in the ocean, and they have some effective measures to protect themselves, among which inkjet is an important way. There are also many nicknames for squid, among which "cuttlefish" and "cuttlefish" are their nicknames, which are named according to their ability to spray ink.
When the squid are in danger, they spray ink. The amount of ink that squid can store is relatively large, and sometimes it can blacken a large area of surrounding sea water. Because the ink they release is toxic and has a paralyzing effect, it can effectively paralyze the other side, interfere with the other side's sense of smell, and make the other side unable to identify the direction. Moreover, under the cover of ink, the squid can easily escape.
ink? Squid spray ink. When they are in danger, they will release the ink produced inside their bodies to protect themselves. The reason why squids have the ability to spray ink is that they have a special structure called ink sac. The ink sac is small, pear-shaped, and located behind the visceral mass, closer to the end of the squid rectum. There are many glands in the ink sac, which have the function of secreting ink. Usually, the ink will be stored in the ink bag. When the squid is in danger, it will discharge the ink, and a large area of sea water around it will be dyed black.
