The first photographs of a live giant squid in its natural habitat were taken on 30 September 2004, by Tsunemi Kubodera (National Science Museum of Japan) and Kyoichi Mori (Ogasawara Whale Watching Association). [9] Their teams had worked together for nearly two years to accomplish this. They used a five-ton fishing boat and only two crew members.
The different properties of the squid's eyes allow it to see a variety of different light sources present in its habitat, primarily downwelling sunlight and bioluminescence. [3] H. heteropsis hatchlings are born with identical eyes of the same size and pigmentation. [3] As they develop, the left eye becomes larger and more pigmented. [3]
Taningia danae, the Dana octopus squid, is a species of squid in the family Octopoteuthidae. It is one of the largest known squid species, reaching a mantle length of 1.7 m (5.6 ft) [3] and total length of 2.3 m (7.5 ft). [4] The largest known specimen, a mature female, weighed 161.4 kg (356 lb). [5]

Sthenoteuthis oualaniensis occurs in a diverse range of environments in the tropical and subtropical Indo-Pacific, often at depths of over 600 m (1,969 ft) deep. [9] [6] [7] Total species biomass has been estimated at between 8-11 million tonnes; the Arabian Sea from November-January is thought to contain one of the highest concentrations (12 to 42 t km −2) of these squids due to population ...
Colossal squid oocytes have been observed at sizes ranging from as large as 3.2x2.1 mm to as small as 1.4x0.5 mm. Sampling of colossal squid ovaries show an average of 2175 eggs per gram. [34] Young squid are thought to spawn near the summer time at surface temperatures of −0.9–0 °C (30.4–32.0 °F). [32]
The squid lives in the twilight zone during the day, hiding from predators in the darkness. At night, like many other animals that live in the twilight zone, it migrates to more shallow waters in ...
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 ...
