Ctenophore
Ctenophores are jellyfish-like animals of the Phylum: Ctenophora, commonly called "comb jellies", "sea gooseberries", "sea walnuts", or "Venus's girdles." Comb jellies are voracious marine predators on plankton. The word ctenophore (pronounced teen-oh-for) comes from Greek meaning "comb-bearers".Ctenophores are vaguely similar in appearance to jellyfish, have eight "comb rows" of fused cilia that are arranged laterally along the sides of the animal and used primarily for locomotion. Many ctenophores have two long tentacles, but some lack tentacles completely. There are about 100 modern species of these marine animals. Due to their soft and fragile bodies, the fossil record for comb jellies is poor. A possible Ctenophore is known from the Middle Cambrian.
