There are only two types of squid that live in Antarctica: the Colossal Squid and the Giant Squid. I believe they, like whales or seals, have an extra layer of blubber/fat that can protect them from the freezing water temperatures. Any other squid brought into Antarctica would die in minutes, if not seconds.

Cephlapods include squid, octopus, cuttlefish and others and are a Mollusk.

The two longer tentacles on a squid serve as feeding arms, they shoot them out simutaniously to grip their prey and bring it back to the mouth.
Squid, octopus, and cuttlefish, rely on ink as a natural defense which they use to protect themselves from their enemies. They can make as much as they need until they die.
