King squid usually inhabits deep-sea areas, mainly in the North Atlantic and the North Pacific. It is estimated that it is about 20 meters long and is one of the second largest mollusks and invertebrates known at present. 20 13, 1 At the beginning of the year, Japanese NHK TV and American Discovery Channel filmed the squid swimming in the deep sea for the first time. The shooting team took a submersible to dive into the deep sea of 630 meters in the North Pacific Ocean, where this 3-meter-long king squid was photographed. This is the first time in the world that a dynamic image of the king squid has been photographed in the deep sea. The second largest squid in the world is the king squid (the first is the giant squid, that is, the king squid, which is generally 2-3 meters larger than the king squid and 4-5 meters more). They generally live in the depths of the ocean, rest in the deep sea during the day and swim to the shallow sea for food at night. Generally, the juvenile king squid is 3-5 meters long, and the adult king squid can be as long as 17- 18 meters.
