Coelenteratan.

Brit.

/sᵻˌlɛntəˈreɪtə/, U.S.

/ˌsiˌlɛntəˈrɑdɑ/

Origin: A borrowing from Latin. Etymon: Latin Coelenterata.

Etymology: < scientific Latin Coelenterata ( R. Leuckart Ueber die Morphologie und die Verwandtschaftsverhältnisse der wirbellosen Thiere (1848) 13) < ancient Greek κοῖλος hollow (see cœlo- comb. form¹) + ἔντερον enteron n. + scientific Latin -ata (see -ate suffix²). Compare German Coelenteraten (1848 in the same source).

Zoology.

1. With plural (or occasionally singular) agreement: a phylum or group of aquatic acoelomate invertebrates comprising the members of the present-day phyla Cnidaria and (in earlier use) Ctenophora. Also with plural agreement: animals of this phylum (collectively or individually); coelenterates.The Cnidaria and Ctenophora are now known to be only superficially similar, having jelly-like bodies and stinging tentacles. The name Coelenterata has effectively been replaced by Cnidaria (see Cnidaria n.).Some earlier examples may refer to sense 2.

2. With plural agreement. A major subdivision of the Metazoa, distinguished from the Coelomata by having an intestinal canal but no body cavity or coelom, and comprising the Porifera (sponges) as well as the Cnidaria and Ctenophora. Now historical.

1870 H. A. Nicholson Man. Zool. I. 16 The six types or plans of structure, upon one or other of which all known animals have been constructed, are technically called ‘sub-kingdoms’, and are known by the names Protozoa, Cœlenterata, Annuloida, Annulosa, Mollusca, and Vertebrata.

These are (1) the Protozoa..; (2) the Cœlenterata, in which the body-cavity serves alike for circulation and digestion, a tribe which includes sponges, corals, and jelly-fish; (3) the Echinodermata..; [etc.].

1953 Systematic Zool. 2 145/2 It was at one time customary to subdivide the Metazoa into Coelenterata and Coelomata or into Radiata and Bilateria.
