All Cnidarians are mobile at some point in their lifetime. For most, it is in the larval stage. Jellyfish start out as mobile larva, then become sessile, then become the mobile jellyfish you are familiar with. Others, like corals, start out as mobile larva, settle down and remain sessile for the rest of their adult life.As adults, hydra can be mobile or sessile, as they choose, but they don't swim far.thers, like corals, start out as mobile larva, settle down and remain sessile for the rest of their adult life.

There are about 10, 000 species of Cnidarians. Cnidaria have no organs like hearts or lungs. They have an internal cavity used for respiration and a gastrovascular cavity (a stomach) with a mouth but they do not have an anus.They possess a body wall made from two layers (the ectoderm and the endoderm) separated by a jelly-like layer called the mesoglea.ll cnidarians have radial symmetrical. There are two major body forms among the Cnidaria-the polyp and the medusa. Sea anemones and corals have the polyp form, while jellyfish are typical medusae. When you look at them, you can see that these body forms are the same except that one is upside down.
