There are around 300 species of squid living in the ocean and they can range in size from less than an inch to the massive 50-foot-long giant squid. The strawberry squid ( Histioteuthis heteropsis ...
While there may be safety in their numbers, the squid are an important prey item for large fish such as tuna and sharks and a number of cetaceans: pygmy killer whales, orcas, Atlantic spotted dolphins, rough-toothed dolphins, and bottlenose dolphins are all known predators of slender inshore squid. Other predators include South African and ...
A frame from the first colour film of a live giant squid in its natural habitat, [nb 1] recorded from a manned submersible off Japan's Ogasawara Islands in July 2012. The animal (#549 on this list) is seen feeding on a 1-metre-long Thysanoteuthis rhombus (diamondback squid), which was used as bait in conjunction with a flashing squid jig. [2]

There are 60 different species of glass squid in the Cranchiidae family and they live in the deep water all around the world. Some of them, like the Cranchia scabra , are as small as four inches.
Squid, on the other hand, can be found to travel vast distances, with some moving as much as 2,000 km in 2.5 months at an average pace of 0.9 body lengths per second. [81] There is a major reason for the difference in movement type and efficiency: anatomy.
Fish predators include striped bass, bluefish, sea bass, mackerel, cod, haddock, pollock, silver hake, red hake, sea raven, spiny dogfish, angel shark, goosefish, dogfish, mako shark, blue marlin and flounder. These squid do have ways of evading predators too. They have a very complex way of swimming called jet propulsion.
