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.
If you want to see a live giant squid, you have to go to where it lives. That happens to be the inky black, icy cold waters 1,650 feet (500 meters) to 3,300 feet (1,000 meters) below the oceanâs surfaceânot a very convenient place to watch wildlife.
