Zoology.

A sea anemone; spec. one of the genus Actinia. Also (in form Actinia): the genus itself.Valid publication of the genus name: Linnaeus Systema naturæ (ed. 12, 1767) 1088; also used by Pallas (1766) for a genus of holothurian.In technical contexts, the word is now restricted to the genus, though the adjective actinian persists in the more general sense.
