? Most animals have natural enemies and means to protect themselves, but these means are different. Squid are one of the mollusks that protect themselves by releasing ink. Squid live in the ocean, and there are many large marine animals that can endanger their lives. Spraying ink is an effective way to protect themselves.
Cuttlefish can spray ink because they have a special structure called an ink sac. At the end of the squid rectum, there is a structure shaped like a tube, which is connected to a sac, which is the ink sac of the squid. The special glands distributed in this ink sac have the ability to produce ink, which will be stored in the ink sac after production. When the squid is attacked by a natural enemy, it releases ink and flees quickly. Of course, it is troublesome for squid to store full ink bags, so they will not release ink easily, and they will only be used when they have to.
? As mentioned above, squid has the ability to spray ink. They have an ink sac in their bodies, and ink can be produced in the ink sac. Ink spraying is an effective means for squid to protect themselves, because the ink sprayed by squid is poisonous and has the effect of paralyzing the senses of the enemy. When the squid releases ink and envelops the enemy in a black ink, the sense of smell of the enemy will be seriously affected, and it will not be able to distinguish the direction around it. Of course, the toxicity of squid ink is not particularly strong, can not directly kill each other, but only play a temporary paralyzing effect.
