The same is true of the chitinous gladius of squid [83] and octopuses. [84] Cirrate octopods have arch-shaped cartilaginous fin supports, [85] which are sometimes referred to as a "shell vestige" or "gladius". [86] The Incirrina have either a pair of rod-shaped stylets or no vestige of an internal shell, [87] and some squid also lack a gladius ...
The colossal squid, species Mesonychoteuthis hamiltoni, was discovered in 1925. [14] This species belongs to the class Cephalopoda and family Cranchiidae. [49] Most of the time, full colossal squid specimens are not collected; as of 2015, only 12 complete colossal squids had ever been recorded, with only half of these being full adults. [4]
We don’t know much about the colossal squid because they are hard to spot. The colossal squid ( Mesonychoteuthis hamiltoni ) is the largest squid in the world, growing 33 feet long and weighing ...
They feed on several species, notably the giant squid, but also the colossal squid, octopuses, and fish such as demersal rays and sharks, [citation needed] but their diet is mainly medium-sized squid. [158] Sperm whales may also possibly prey upon swordfish on rare occasions. [159] Some prey may be taken accidentally while eating other items. [158]
The southern sleeper shark feeds primarily on cephalopods, especially squid — including the giant and colossal squids — and numerous fishes.Documented stomach contents of individual sleeper sharks have also, albeit infrequently, contained the remains of marine mammals or seabirds, possibly as a result of scavenging on sunken carcasses or whale falls.

Ellis (1999) suggested the Egede monster might have been a giant squid. There is a Tlingit legend about a sea monster named Gunakadeit (Goo-na'-ka-date) who brought prosperity and good luck to a village in crisis, people starving in the home they made for themselves on the southeastern coast of Alaska.
Sleeper sharks are a poorly studied [15] deep-sea shark found in all oceans. [16] They contain antifreeze to survive in cold temperatures, and may feed on colossal squid. In Iceland, they are hunted for food. They are allowed to rot for months until the poisonous antifreeze degrades, and they are safe to eat. [17] Squalidae: Dogfish sharks: 3 31
Cephalopod include octopus, squid and cuttlefish. They are found in all oceans, and neurologically are the most advanced of the invertebrates. [59] About 800 living species of marine cephalopods have been identified, [60] and an estimated 11,000 extinct taxa have been described. [61] There are no fully freshwater cephalopods. [62]
