Etymology: Acanthemblemaria: Greek, akantha = thorn + Greek, emblema, -atos, anything that is nailed, knocked in; also anything with bass or high relief (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 15 m (Ref. 11482). Tropical; 29°N - 4°N, 112°W - 85°W (Ref. 56271)

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 11482)
This species is distinguished from A. hastingsi in having melanophores on the lower jaws that do not reach all the way to the distal end; it possess a red primary bright head color (vs. orange), and the windowing effect around that color is not present or is less distinct; almost not having melanophores reaching the base of the first dorsal fin and more typically have a dark, round spot or stretched out spot instead of a swath (Ref. 84469).
Inhabits empty barnacles and worm or mollusk tubes on rocky reefs. Feeds on zooplankton.
