The known predators of adult giant squid include sperm whales, pilot whales, [35] [36] southern sleeper sharks, [37] and in some regions killer whales. [38] Juveniles may fall prey to other large deep sea predators. Because sperm whales are skilled at locating giant squid, scientists have tried to observe them to study the squid.
The giant squid nevertheless remains a rarely encountered animal, especially considering its wide distribution and large size, [60] with Richard Ellis writing that "each giant squid that washes up or is taken from the stomach of a sperm whale is still an occasion for a teuthological celebration".
A frame from the first colour film of a live giant squid in its natural habitat, [nb 1] recorded from a manned submersible off Japan's Ogasawara Islands in July 2012. The animal (#549 on this list) is seen feeding on a 1-metre-long Thysanoteuthis rhombus (diamondback squid), which was used as bait in conjunction with a flashing squid jig. [2]
It is sometimes called the Antarctic cranch squid or giant squid (not to be confused with the giant squid in genus Architeuthis) and is believed to be the largest squid species in terms of mass. [3] It is the only recognized member of the genus Mesonychoteuthis and is known from only a small number of specimens . [ 4 ]
Juveniles of this species have been observed moving rapidly in the direction of potential predators, as if hunting, to disorient and startle the threat with a mock attack. [8] In 2012, T. danae was filmed twice more during a search for the giant squid for the Discovery Channel Special, Monster Squid: The Giant Is Real. [9]
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 predators that feed on T. rhombus include various species of ommastrephid squids, giant squid (Architeuthis dux), [15] dolphinfish (Coryphaena hippurus), lancetfish, tuna, swordfish, snake mackerel (Gempylus serpens), and sharks. Other predators include cetaceans such as oceanic dolphins, rough-toothed dolphins, false killer whales and ...
