Liquid skeleton

Liquid skeleton

A Liquid skeleton performs the same function as a bony skeleton. Some animals do not seem to have a skeleton at all. Their soft bodies are filled with water. Their muscles squeeze against the liquid which keeps the body firm. Their muscles also can squeeze in different parts of the body. This changes their shapes and helps them to move along. This is called liquid skeleton.
