With such limited opportunities for study, it is difficult to characterize the biology and ecology of such a rare species, even one as large as the colossal squid. Reaching combined body and tentacle lengths up to 46 feet 14 m and weights of at least pounds kg , the colossal squid is a very large deep-sea predator.
Like in many large species, all the largest individuals are female. They eat small and large fishes including the Patagonian toothfish and other squids. Their tentacles are covered with suckers that are equipped with strong, sharp hooks, used in both capturing prey and fighting off predation.
In fact, an pound 5-kilogram toothfish—known to be a typical meal for colossal squid—could sustain a 1,pound kilogram adult for days, the study team estimates. Overall, the squid's energy requirements are to times lower than those of warm-blooded whales, the other top predators in Antarctic waters. And since the squid probably doesn't actively hunt, Rosa added, its dinner plate-size eyes are likely an adaptation for avoiding predators, such as sperm whales and sleeper sharks.
The colossal squid findings were published online last month in the Journal of the Marine Biological Association of the United Kingdom. All rights reserved. Share Tweet Email.

Go Further. Many of these whales even bear scars from the squid's suction-cupped tentacles. The main defense mechanism of the squid is a dark, black ink, which can used to create a smoke screen.
This ink can temporarily confuse predators, allowing the squid precious time to attempt their escape. Very little is known about the reproductive behavior of the giant squid. It is believed that they reach maturity at the age of three years and that the males mature at a smaller size than the females.
The females lay a large number of eggs. Juveniles have been observed in the surface waters off the coast of New Zealand. Several aquariums are attempting to capture and maintain juvenile specimens in an attempt to learn more about this mysterious creature. Giant squid are found throughout all of the world's oceans.
They are usually found at depths of between 1, feet meters and about 2, feet meters , although there are documented reports of specimens found as deep as 3, feet meters. Giant Squid are rare in polar and tropical regions. To search this site, type your search word s in the box below and click the search button:.

Scientists don't know enough about these beasts to say for sure what their range is, but giant squid carcasses have been found in all of the world's oceans. All rights reserved.
