Giant Squid


The Biggest Animals Kingdom and in The World | Giant Squid | The giant squid is the second largest mollusc and is the second largest of all invertebrates. Some extinct cephalopods, such as Tusoteuthis vampyromorphid the Cretaceous, Cretaceous and Ordovician coleoids Yezoteuthis Cameroceras Nautiloid could do more. Giant squid size, the total length of all, it has often been exaggerated. According to giant squid expert Steve O'Shea, such lengths were likely achieved by stretching the two tentacles like elastic bands Based on the examination of 130 samples and the peaks are inside sperm whales, giant squid mantles "knows not exceed 2.25 m (7.4 ft). Giant squid are sexually dimorphic. The maximum weight is estimated at 275 kg (610 lb) for females 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 (0.020 to 0.055 inches) in length and 0.3 to 0.7 mm (0.012 to 0.028 inch) wide. Females have a median ovary that the rear end of the mantle cavity and associated contours oviducts where mature eggs pass through the oviduct glands and the glands nidamental. Men, like most other cephalopods, the single testicle produces sperm that later move into a complex system of glands that produce spermatophores. Grip the penis is more than 90 cm (35 inches) long and extends the mantle.

Can be transferred in sacs called spermatophores spermatangia, arms male injected into 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 most giant squid caught by trawl in New Zealand waters have been associated with the local hoki (Macruronus novaezelandiae) hoki fishery are not included in the diet of squid. This suggests that the giant dam squid and hoki in the same animal giant squid are widespread, occurring in all oceans of the world.
