The majority of squid are no more than 60 centimeter long, although the giant squid may reach 13 meter in length. Squid are a large, diverse group of marine cephalopods. Like all cephalopods, squid are distinguished by having a distinct head, bilateral symmetry, a mantle, and arms. Squid, like cuttlefish, have eight arms and two tentacles arranged in pairs.
In Antarctica’s Ross Sea, a fishing boat has caught what is likely the world’s biggest known colossal squid.
On February 22, 2007, it was announced by authorities in New Zealand that the largest known Colossal Squid had been captured. The specimen measured 10 metres (33 feet) in length and weighed 495 kilograms.
