Comb Jelly

Description:

Comb jellies are beautiful, oval-shaped animals with eight rows of tiny comblike plates that they beat to move themselves through the water. As they swim, the comb rows diffract light to produce a shimmering, rainbow effect. Voracious predators on other jellies, some can expand their stomachs to hold prey nearly half their own size. Jellies are simple creatures with few specialized organs. Most jellies can detect chemical traces in the water that allow them to locate food, and many are equipped with a gravity-sensitive structure, called a statocyst, that gives them a sense of up and down in the water.
