In the coelenterates
there is an alternation of generations between a sexual, motile, medusa stage and a sessile, asexual, polyp stage.

Eggs of these protostomes have certain features that make them more similar to mammalian oocytes than to echinoderm or coelenterate

Harry Beal Torrey (1873-1970) of California, USA, and his research on hydroids and other coelenterates
At that stage almost all the main groups were observed as prey items such as crustaceans, teleosts, digested matter, mollusks, polychaete and coelenterates
, (84) echinoderms, (85) and worms (86)--mammals
Species with exterilium larvae are hypothesized to benefit in several ways: 1) an increase in the length and surface area of the gut greatly enhances digestion in oligotrophic environments (Moser 1981); 2) the exterilium projection protects against predators because pigment patterns and the physical structure of this feature mimic siphonophores or poisonous coelenterates
(Fraser and Smith, 1974; Moser, 1981; Gordon et al.
Extending for a distance of about 200 km, it, like other coral reefs, is composed of colonial coelenterates
and encrusting algae.
11) Several species of microorganisms, fish, crustaceans, polychaetes, echinoderms, coelenterates
and molluscs have been found in hydrothermal vent areas.
