Acalephan.

Brit.

/akəˈliːfə/, U.S.

/ækəˈlifə/

Inflections: Plural Acalephae.

Origin: A borrowing from Latin. Etymons: Latin Acalepha; Latin Acalephae.

Etymology: Partly < scientific Latin Acalepha, class name (see quot. 1822), alteration (see -a suffix²) of Acalephae (see below); and partly < scientific Latin Acalephae, class name, feminine plural ( Cuvier Règne animal (1817) IV. 5) < ancient Greek ἀκαλήϕη stinging nettle, sea anemone (so called on account of its stinging properties), of unknown origin. Compare French Acalèphes , plural (Cuvier: see above). Compare earlier acaleph n. and later acalephan adj.

Zoology. Now historical.

With plural agreement: a former class of coelenterate organisms including jellyfish, comb jellies, siphonophores, and (originally) sea anemones. With singular agreement (also in form acalepha): an animal of this class (usually in plural, the animals of this class collectively). Introduced by Cuvier as a subdivision of Radiata; the sea anemones were later moved to the class Polypi. By some later authors restricted to the Scyphozoa or true jellyfish.
