The giant squid, also known as the "king squid", is a mollusk. Its so-called "teeth" are a pair of very hard mouths, and it is said that the hard mouths of the king squid eaten by the sperm whale have never been digested. The king squid is always in the deep sea and rarely goes to the shallow sea or offshore, so human beings know very little about it. As you know, the less we know about it, the more mysterious it is, and the more mysterious and large it is, the more it conjures up the word "scary" in people's minds. In fact, although the king squid is big, but not scary, because it will be in the shallow sea because the water pressure is too low and the internal pressure of its body is too high, which will make its internal organs and blood vessels burst and die. And human beings can not dive so deep in the sea, so human beings have never seen a living king squid.
