Cockatoo Squid This transparent cockatoo squid (Leachia sp.), also known as a glass squid, lives in the depths of the ocean and has many adaptations to help it survive there. It retains ammonia solutions inside its body that give it a balloon-like shape and help it float.
The eight arms of the Colossal Squid also carry fixed hooks which the Giant Squid does not have. Both the Colossal Squid and the Giant Squid live in deep water, perhaps as much as 3,300 feet (1000 meters) or more beneath the surface, where there is very little light. To help them hunt their prey in the darkness at that depth they have extremely large eyes.
