Giant squid are very widespread, occurring in all oceans of the world. They are usually found near continental and island slopes from the North Atlantic Ocean, especially Newfoundland, Norway, the northern British Isles, Spain and the oceanic islands of the Azores and Madeira, to the South Atlantic around southern Africa, the North Pacific around Japan, and the southwestern Pacific around New Zealand and Australia. Specimens are rare in tropical and polar latitudes.
The giant squid is the second largest mollusc and the second largest of all extant invertebrates. It is only exceeded by the colossal squid, Mesonychoteuthis hamiltoni, which may have a mantle nearly twice as long. Some extinct cephalopods, such as Tusoteuthis vampyromorphid Cretaceous, the Yezoteuthis coleoid Cretaceous and Ordovician nautiloid Cameroceras may have grown bigger. Giant squid size, so the total length, often exaggerated. Reports of specimens reaching and even exceeding 20 m (66 ft) wide, but no animals approaching this size have been scientifically documented.
According to giant squid expert Steve O'Shea, such lengths were likely achieved by greatly stretching the two tentacles like elastic bands. Based on the examination of 130 specimens and half found in sperm whales, giant squid mantle 'unknown exceeding 2.25 m (7.4 ft). Including the head and arms, but excluding the tentacles, the length very rarely exceeds 5 m (16 ft). Maximum total length, when measured relaxed post mortem, is estimated to 13 m (43 ft) for females and 10 m (33 ft) for males from fin posterior to the tip of the two long tentacles
Giant squid are sexually dimorphic. Maximum weight is estimated at 275 kg (610 lb) for women and 150 kg (330 lb) for males. Little is known about the reproductive cycle of giant squid. It is believed that they reach sexual maturity at three years, males reach sexual maturity at a smaller size than females. Females produce large quantities of eggs, sometimes more than 5 kg (11 lb), which is an average of 0.5 to 1.4 mm (.020 to .055 inches) in length and 0.3 to 0.7 mm (0.012 - 0.028 inches) wide.
Females have a median ovary that the back of the mantle cavity and associated contour oviduct where the egg mature eggs pass through lymph channels and lymph nidamental. Men, like most other squid, sole testes produce sperm, which is then moved to a complex system of glands that produce spermatophores. Hold the penis of more than 90 cm (35 inches) long and extends coat. Can be transferred in sacs called spermatophores spermatangia, arm injected male to the female.
Recent studies have shown food giant squid deep-sea fish and other squid species. It is believed that solitary hunters, as only individual giant squid have been caught in fishing nets. Although the giant squid caught by trawl in the New Zealand waters have been associated with the fishery (Macruronus novaezelandiae) local hockey hockey is not included in the diet of squid. This suggests that the squid giant dam and hockey in the giant squid of the same animal that extensive, occur in all oceans of the world.
