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.
What do we know about the life and habits of the colossal squid? We know very little about the colossal squidâs life history, diet, or behaviour, because they live at extreme depths in freezing water. They are also very rarely captured. The first report of a colossal squid was in 1925, when the head and arms were discovered in a sperm whale stomach.
