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.
Viperfish are found in tropical and temperate waters throughout the world at depths of up to 9,000 feet (2,800 meters). They are rarely seen by humans, although specimens do sometimes show up in the catches of deep water trawlers.
