? Squid is a common mollusk, which lives in the ocean and is generally common in deep water areas. Most of the squid itself is non-toxic, and many of them can be eaten, which is a very common food. Only one species of squid is venomous, so overall there are fewer venomous squid among all squid species.
However, although most squid are not toxic themselves, they can release toxic substances, namely ink. Cuttlefish are also called "cuttlefish" because they can release ink. The body of squid has a special structure of ink sac, which has the function of secreting ink and can store ink. Because it is not easy to produce ink, squid usually cherish the ink and will not release it easily. When the squid encounters a very powerful enemy, they will release the ink, which is poisonous and can paralyze the enemy's senses for a period of time, at which time the squid will take this opportunity to run away.
has been introduced above. Most squid are non-toxic, only a small number of squid are poisonous. Specifically, there is only one kind of poisonous squid in the world, called "flame squid", which is named for its appearance similar to flame. Flame squids are poisonous in their muscles, and if other large animals eat them, they may be poisoned. Humans will also be poisoned if they eat flame squid, whose toxicity has been proved in toxicology.
Of course, other squid can release ink, and the ink is poisonous. Of course, their ink toxicity is not strong, but has a certain paralyzing effect. After the squid has successfully escaped, other animals affected by the ink will return to normal later.
