First, let's learn about the king squid.
I believe everyone is familiar with the word "sea monster". Usually, sea monsters are described as a huge creature with long tentacles, and they "make waves" in the sea. Of course, the sea monster is just that people didn't know enough about the ocean before, and they got this name for some large creatures in the ocean. Today, the king squid that we are going to talk about is once considered as a "sea monster".
The myth of the "sea monster" of the king squid lasted until the end of the 80n generation in the19th century, because the body of a king squid lay quietly on the beach in Newfoundland, Atlantic Ocean.
After the king squid was confirmed, the mystery of the king squid was slowly unveiled. The king squid is the only species under the gun-shaped king sepiidae, and its size is second only to that under the Cephalopoda. The average body length of adult king squid is about 8 meters, and the maximum length is 20 meters. From the appearance, the body of the squid is conical, with four pairs of wrists, of which the second pair and the fourth pair are the longest. The wrist of the squid is covered with suction cups, which is not a simple adsorption function, because the inside of the suction cups is covered with keratinized serrated ring teeth. This means that the king squid has a strong predation ability, and once the prey is sucked (bitten), it is difficult to escape.
The king squid is a pure carnivorous marine creature, and in its hunting, the largest proportion is cephalopods with other questions smaller than its own. Of course, it also uses its wrists to net some small fish for food. The mobility of squid is poor in the sea, because its water spraying ability is weak, but its body contains more ammonia ions, so it usually lives in the upper layer of seawater, about 200-400 meters in seawater.
