February 22, 2007—In Antarctica's Ross Sea, a fishing boat has caught what is likely the world's biggest known colossal squid (yes, that's the species' name), New Zealand officials announced today.

Heavier than even giant squid, colossal squid (Mesonychoteuthis hamiltoni) have eyes as wide as dinner plates and sharp hooks on some of their suckers. The new specimen weighs in at an estimated 990 pounds (450 kilograms).

The sea monster had become entangled while feeding on Patagonian toothfish (toothfish photos) caught on long lines of hooks. The crew then maneuvered the squid into a net and painstakingly hauled it aboard—a two-hour process.

The animal was frozen and placed in a massive freezer below decks. Now in New Zealand, the carcass awaits scientific analysis.

"Even basic questions such as how large does this species grow to and how long does it live for are not yet known," said New Zealand Fisheries Minister Jim Anderton in a statement.
