Self-defense methods

The ink in the squid's body is usually stored in the ink sac in its belly. When attacked by enemies, they will eject a stream of ink from the ink sac to kill them. The surrounding sea water was dyed black, and then he took the opportunity to escape. Moreover, squid ink contains toxins that can be used to paralyze enemies. It takes a long time to store the ink in this chamber, so they will not release the ink at will unless absolutely necessary.

Squid, whose real name is Wu Qi, is also called flower branch, cuttlefish or cuttlefish.

It is an animal in the phylum Cephalopod, order Sepia, in the phylum Mollusca. When a squid encounters a strong enemy, it will use "ink jet" as a method of escape and wait for an opportunity to leave, hence its names such as "squid" and "cuttlefish". There are small pigment sacs in its skin that change color and size with changes in "emotion". Squids can leap out of the sea and have amazing aerial capabilities.

The squid has a flat and soft body, which is very suitable for living on the seabed. Squid usually move slowly like waves, but when encountering danger, they will leave powerful enemies behind at a speed of 15 meters per second (54 kilometers per hour). Some squid can move at a maximum speed of 150 kilometers per hour. Not only does it escape quickly, it also hunts food faster. Squids are color-changers in the water. There are millions of red, yellow, blue, black and other pigment cells in their bodies. They can respond within a second or two by adjusting the size of the pigment sacs in their bodies to change their own color in order to adapt. environment and escape from enemies. There is an ink sac in the body of the squid, which contains thick black ink. When it encounters an enemy, it quickly spurts out, dyeing the surrounding seawater black to cover its escape.
