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 sparkling enope squid is found in the Western Pacific ocean at depths of 183 to 366 metres (600â1200 feet) and is bioluminescent. Each tentacle has a photophore organ, which produces light. When flashed, the light attracts small fish, which the squid can feed upon.
