The giant squid (Architeuthis dux, pictured) was for a long time thought to be the largest extant cephalopod. It is now known that the colossal squid (Mesonychoteuthis hamiltoni) attains an even greater maximum size. The giant squid seen here measured 9.24 m (30.3 ft) in total length and had a mantle length of 1.79 m (5.9 ft).
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".
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.
Marine Patch says that they can dive 2,000 meters, or about 6,200 feet for up to two hours while hunting giant squid, sharks, skates, and fish. "Squid just so happens to be the sperm whales ...
A piece of sperm whale skin with giant squid sucker scars. Sperm whales usually dive between 300 and 800 metres (980 and 2,620 ft), and sometimes 1 to 2 kilometres (3,300 to 6,600 ft), in search of food. [155] Such dives can last more than an hour. [155]
The giant squid also exhibits abyssal gigantism, but the colossal squid is heavier. [29] Although it is unclear what the maximum weight for colossal squids is, analysis of squid beak dimensions from sperm whale stomachs provided estimates that colossal squids may weigh up to 700 kg or 1,500 lb.

By RYAN GORMAN Amazing footage has emerged of a squid attacking a submarine. Greenpeace posted a video online Friday showing the giant squid attacking the underwater vessel during a recent excursion.
On November 20, 1820, while at sea in the southern Pacific Ocean under the command of Captain George Pollard Jr., the ship was attacked and sunk by a sperm whale. About 2,000 nautical miles (3,700 km) from the coast of South America, the 20-man crew was forced to make for land in three whaleboats with what food and water they could salvage from ...
