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.
They have no cornea over their eyes, and their tentacles are lined with suckers and/or hooks.
