King Squid, also known as King Squid, is a kind of squid that lives in the deep sea of the Pacific Ocean and the Atlantic Ocean. Its natural enemy is sperm whale, which is the largest invertebrate and the longest mollusk known to mankind. The male seems to be smaller than the female. The total length of female squid is about 12- 13 meters, its body length is about 4 meters, and its tentacles length is 10 meters or even longer, while the total length of male squid is about 10 meters. Whether male or female, its maximum length does not exceed13m.

The exact distribution of the squid is unknown, but the records in the North Atlantic, the North Pacific and the coasts of South Africa and New Zealand are very common, and its distribution area is related to the continental shelf and islands. It is rarely distributed in tropical and polar high latitudes. The habitat water layer is extensive and does not belong to typical deep-sea species. The king squid feeds on other cephalopods (such as squid and soft fish) and small fish, and cannibalism is also a major feature of the king squid.
