What's the difference between alcyonacea and gorgonian?
Alcyonacea
Definition:
(n. pl.) A group of soft-bodied Alcyonaria, of which Alcyonium is the type. See Illust. under Alcyonaria.
Example Sentences:
Gorgonian
Definition:
(a.) Pertaining to, or resembling, a Gorgon; terrifying into stone; terrific.
(a.) Pertaining to the Gorgoniacea; as, gorgonian coral.
(n.) One of the Gorgoniacea.
Example Sentences:

(5) Despite the considerable effort expended in the exploration of alternative, large-scale sources of eicosanoids, the first-discovered nonmammalian source--the gorgonian Plexaura homomalla--remains by far the most impressive.
(6) In gorgonian outlines, due to their limited multi-scale organization, we have found curved trends typical of non-fractal lines.
