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.
Tsunemi Kubodera of the National Museum of Nature and Science of Japan/AP. Giant squid live up to their name: the largest giant squid ever recorded by scientists was almost 43 feet (13 meters) long, and may have weighed nearly a ton. Youâd think such a huge animal would be hard to miss. But because the ocean is vast and giant squid live deep underwater, they remain elusive and are rarely seen: most of what we know comes from dead carcasses that floated to the surface and were found by fishermen.
