New Zealand Fisheries Minister Jim Anderton said the squid, weighing an estimated 990 pounds, took two hours to land in Antarctic waters.

The Colossal Squid (Mesonychoteuthis hamiltoni), sometimes called the Antarctic or Giant Cranch Squid, is believed to be the largest squid species, and the only member of the genus Mesonychoteuthis. Current estimates put its maximum size at 14 meters (46 feet), based on analysis of smaller and immature specimens, making it the largest known invertebrate.

 

Biology

Unlike the various giant squid species whose tentacles are equipped with suckers lined with small teeth, the tentacles of the Colossal Squid are tipped with a fierce mixture of suckers and swiveling hooks. Its body is wider and stouter, and therefore heavier, than that of the giant squid. Colossal Squids are believed to have a longer mantle than giant squids, although their tentacles are shorter.

The beak of Mesonychoteuthis hamiltoni is the largest known of any squid, exceeding that of Architeuthis in size and robustness. The Colossal Squid is also believed to have the largest eyes in the animal kingdom (even larger than those of giant squid).

The squid's known range extends thousands of miles northward from Antarctica to southern South America, southern South Africa, and the southern tip of New Zealand, making it primarily an inhabitant of the entire circumantarctic Southern Ocean.

While little is known about the life of this creature, it is believed to hunt prey such as chaetognatha and squid in the deep ocean using bioluminescence. Based on capture depths of a few specimens, as well as beaks found in sperm whale stomachs, the adult squid ranges at least to a depth of 2200 m, while juveniles can go as deep as 1000 m.

The squid's method of reproduction has not been observed, although some data on their reproduction can be inferred from anatomy. Since males lack an organ called a hectocotylus (a tentacle used in other cephalopods to transfer a spermatophore to the female), they probably use a penis instead, which would be used to directly implant sperm into females.

Many Sperm whales carry scars on their backs believed to be caused by the hooks of Colossal Squid. Colossal Squid are a major prey item for Antarctic sperm whales feeding in the Southern Ocean; 14% of the squid beaks found in the stomachs of these sperm whales are those of the Colossal Squid, which indicates that Colossal Squid make up 77% of the biomass consumed by these whales.[2] Many other animals also feed on this squid, including the beaked whales (such as the bottlenose whales), Pilot Whale, Southern Elephant Seal, Patagonian toothfish, Pacific sleeper shark, and albatross (e.g., the Wandering and Sooty albatrosses). However, beaks from mature adults have only been recovered from those animals large enough to take such prey (i.e., the sperm whale and Pacific sleeper shark), while the remaining predators are limited to eating juveniles or young adults.

 

Timeline

Complete specimen caught in 2003
Complete specimen caught in 2003

This species was first discovered in 1925, in the form of two tentacles found in the stomach of a sperm whale. In 1981, a Russian trawler in the Ross Sea, off the coast of Antarctica, caught a large squid with a total length of 13 feet / 4 m (see image at top), which was later identified as an immature female of Mesonychoteuthis hamiltoni. In 2003, a complete specimen was found near the surface with a total length of 6 m (20 feet) and a mantle length of 2.5 m (8 feet). On June 25, 2005, a specimen was captured at a depth of 1625 m while taking a toothfish from a longline off South Georgia Island. Although the mantle was not brought aboard, the mantle length was estimated at over 2.5 m (8 feet), and the tentacles measured 230cm. The animal is thought to have weighed between 150 and 200 kg.[3]

I'd need a larger fridge for this... stake, casserole, steamed, fried...

Varieties of menus on my mind right now...

what's the first bid? Haven't tried giant squid before... has anybody?

Am I the only one who's always sort of disappointed by the size of these real-life giant squids? Too much Jules Verne and Johnny Quest growing up?

Yikes.

I don't think I'd want to die by squid. They're ferocious suckers.

In this case they may have thought it was fatally injured by the fish hooks but it gives me pause to automatically kill these enormous creatures. Be it huge squids or sharks or snakes or whatever. When I see a tremendous shark hanging upside down or dead at port I feel like now the world is missing something wonderful. Albeit I'm the first one to pour over their photographs, I wish we did not have to catch and or kill magnificent things to study them or show them off. Just let them live like they have been doing.

'Its estimated weight is about 450 kilograms.'

'The species is known as the colossal squid, shorter but much heavier than the better known giant squid.'
