Colossal Squid

The colossal squid is the currently known largest squid species in terms of mass and is the only member of genus Mesonychoteuthis. It is 12-14 meters (39-46 feet) long and weights up to 750 kilograms (1,650 lbs). It is the largest known invertebrate. The colossal squid is bioluminescent and is known to live in the deep Antarctic sea. Not much is known about the colossal squid other than few samples we've gotten from fisheries in the Antarctic sea, giving us limited opportunities.
