Etymology: Plesiops: Greek, plesios = near + Greek, ops = appearance (Ref. 45335); corallicola: Specific epithet refers to the habitat of the species, a coral-dweller (Ref. 27772).

Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 23 m (Ref. 9710), usually 1 - 10 m (Ref. 27115). Tropical; 32°N - 24°S
Indo-Pacific: Madagascar to the Line Islands; north to southern Japan, south to the southern Great Barrier Reef and Tonga. Throughout Micronesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 90102)
soft rays: 8. Coloration can vary from pale gray with black blotches and blue dots to an almost uniformly black except for the ever-present blue ocellus on the edge of its operculum.
Adults are benthic which occur inshore (Ref. 7300). Relatively common on reef flats, searching under rocks or in crevices for small fishes and crustaceans which serve as food (Ref. 1602). Common, but hidden in holes by day. They venture out to feed on small invertebrates and fishes at night (Ref. 9710). Apparently, gastropods form an important component of the diet as indicated by X-ray radiographs (Ref. 27772). Eggs are guarded by the male parent (Ref. 205). Minimum depth reported from Ref. 27115.
