Jellyfish Collection

Jellyfish belong to the cnidarian phylum and subdivision of coelenterates. Your body, which is 98 to 99 percent water, contains two layers of cells: an outer one that covers the body and an inner one that lines the body. There is a gelatinous mass between the two layers. This supports the body and serves as a storage for oxygen. The smallest species measure a millimeter in diameter, the largest several meters
