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]
This list of colossal squid specimens and sightings is a timeline of recorded human encounters with members of the genus Mesonychoteuthis, popularly known as colossal squid. It includes animals that were caught by fishermen, recovered (in whole or in part) from sperm whales and other predatory species, as well as those reliably sighted at sea.

Examination of a 9 m (30 ft) giant squid, the second largest cephalopod, that washed ashore in Norway in 1954 In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range.
A large colossal squid caught in 2014 and dissected at the Museum of New Zealand Te Papa Tongarewa had eyes some 35–37 cm (14–15 in) across. [166] There are unconfirmed reports from the 19th century of giant squid eyes up to 40 cm (1.3 ft) across. [167]
Colossal squid use their beaks for shearing and slicing their prey's flesh to allow the pieces to travel the narrow esophagus. One of the largest beaks ever recorded was on a 495-kilogram (1,091 lb) colossal squid. The beak had a lower rostral length of 42.5 millimeters (1 + 11 ⁄ 16 in).
