Description: A small bottom dwelling (benthic) species. The genus Meiacanthus is one of 31 belonging to the family Blenniidae (combtooth blennies). Burgess lists 11 species, none of which exceed 9 cm. They are “naked” or with modified scales and have a continuous dorsal fin. This species has lateral stripes (blue/black) through most of the body(white); an upper stripe starting on top of the skull extending down the body under the dorsal fin to the base of the caudal fin; a second stripe extending from the blunt snout, through the eye towards the caudal fin; and a lower stripe beginning on the lower jaw and extending towards the caudal fin. The dorsal and anal fin each have a dark stripe like marking. The caudal fin has dark spots. Some photos indicate a slight yellow coloration in the white fields.

Original description: Cuvier & Valenciennes described Blennechisgrammistes, in 1836 in Hist. Nat. Poiss. v. 11; ref. 1005. from a single specimen (Holotype) collected in Java. This is the only reference found connecting Cuvier & Valenciennes to a Blenniidae with a species of

Vernacular name(s): Striped blenny, Creamy striped blennyGrammistes blenny

Word origin: The genus Meiacanthus appears to be from the Greek root(s) mei meaning less; and acanth meaning a spine. (spineless) The genus grammistes is less clear. Two possible combinations (?) are found; from the Latin roots gram meaning grass; and mist meaning a mixing, or from the Greek word gramm meaning a letter or writing; -ist is a superlative ending. Collection notes indicate that the specimens have been collected in areas of coral sand, however no mention of sea grasses are mentioned (grass mixing).

The genus Blennechis is from the Greek roots blenn meaning a kind of fish; and echis meaning a viper or adder. This genus is no longer used.
