What does coelenteric mean?
Coelenteric is a formal, now somewhat dated zoological adjective meaning of or relating to the Coelenterata, the historical grouping now represented chiefly by cnidarians such as jellyfishes, sea anemones, and corals. It is especially associated with a simple body plan in which a gastrovascular cavity serves as both the digestive cavity and the main internal space. The word therefore appears in older biological texts discussing coelenteric animals, tissues, and affinities. In modern scientific writing, “cnidarian” is usually clearer when referring specifically to members of Cnidaria, because Coelenterata is obsolete and reflects an older approach to classification that sometimes included ctenophores. Although uncommon in everyday English, coelenteric remains useful for recognizing historical zoological terminology and understanding the development of biological classification. It should not be confused with “coelom,” a distinct body cavity, or with “coelenteron,” the digestive cavity itself.

- Of or relating to the Coelenterata or to the gastrovascular body plan characteristic of coelenterate animals.
"The lecture examined the coelenteric body plan, in which a single cavity performs both digestive and circulatory functions."
"The museum's nineteenth-century text describes the species as having a coelenteric body organization."
"Older classifications referred to jellyfishes, corals, and related animals through the coelenteric grouping."
“Coelenteric” is a time capsule from old zoology: it recalls the catch-all Coelenterata, whose members are now classified chiefly as cnidarians.

Etymology of coelenteric
Coelenteric was formed in English from coelenterate plus the suffix -ic. Coelenterate comes through New Latin from the Greek roots koilos, meaning “hollow,” and enteron, meaning “intestine,” a reference to the gastrovascular cavity. Related English forms include coelenteron, coelom, and enteron, all preserving one or both of these Greek elements.
How coelenteric is actually used
This is formal, dated zoological English, encountered mainly in historical and specialized biological writing. In modern scientific contexts, “cnidarian” is usually more precise when referring to members of Cnidaria.
