It’s possible that they grow from a few millimetres long to over 10 metres, in just two years! They are usually found at depths of between 1,000 feet (300 meters) and about 2,000 feet (600 meters), although there are documented reports of specimens found as deep as 3,800 feet (1175 meters). Thought to be the largest or second largest living invertebrate, next to the colossal squid (Mesonychoteuthis hamiltoni), the giant squid has been frequently depicted as a sea monster in literature and by mariners throughout history. Many things still remain uncertain, such as their maximum size or life span, though it is thought to have a relatively short lifespan of approximately five years. 21. Giant squid, Architeuthis dux (Steenstrup, 1857), of the family Architeuthidae, are possibly the largest known cephalopod, the largest known mollusk and, likely, the largest invertebrate ever known to exist (except for possibly colossal squids, Mesonychoteuthis hamiltoni which may have a mantle length nearly twice the size of the giant squid!). “The Kraken” 2.

They are a rare species with parrot-like beak, eight arms, two tentacles to feed them. Scientists don’t know how old the most recent colossal squid specimen is. For giant squid such as Architeuthis, a paucity of size-at-age data means that growth is only inferred from isolated field specimens, based on either statoliths or isotopic analyses of tissue. Giant 'paperclip' squid may have lived for centuries. The giant squid can grow to an enormous size and is characterized by having a head, a mantle with two large fins, eight arms, and two tentacles. It may come as a surprise for many, but the death of these creatures is related to their reproduction process.

Laboratory and field studies suggest that cephalopod growth occurs rapidly and is linked to temperature throughout a short life span. Further, it remains the second largest of all known species of squid. The giant squid holds many size records. The eggs hatch out into tiny versions of the adult which become mature adults in one–three years.

Giant squid, (genus Architeuthis), any member of a genus of large, elusive cephalopods inhabiting deep regions of temperate to subtropical marine waters. Secondly, this astounding animal achieves its enormous size through the principle of deep-sea gigantism. Culture And Giants Squids. Colossal Squid Reproduction and Lifespan. The Humboldt squid is very aggressive and will even attack sharks in the water. Age and Lifespan. This is due to the overall design of their bodies. Distribution .
