n.

Coelenterata
Coelenterata is term encompassing two animal
phyla, the
Ctenophora (comb jellies) and the
Cnidaria (
coral animals, true jellies, sea anemones, sea pens, and their allies). The name comes from the
Greek "
koilos" ("hollow bellied"), referring to the hollow
body cavity common to these two phyla. They have very simple
tissue organization, with only two layers of cells, external and internal and radial symmetry. Some of the examples are
corals,
sea anemone which are colonial and
hydra,
jelly fish which are solitary.
