This gallery includes 82 line drawings of jellyfish. Jellyfish are in the phylum cnidaria, and are free-swimming creatures that are also called medusa.

Jellyfish have several different morphologies that represent several different cnidarian classes including the Scyphozoa. Stages in the development of a scyphozoan jellfish shows the attached young.

"These fragile creatures are able to make long voyages on the surface of the sea. Their nature is such that they are required to keep constantly moving in order to sustain themselves in the fluid which they inhabit. There is a double movement of their light skeletons, which may be compared to the action of respiration in the human hest."

They only make the animal able to distinguish between light and darkness or shadow. This diagram shows the simple eye or a jellyfish.
