Etymology: Enneapterygius: Greek, ennea = nine times + Greek, pterygion = little fin (Ref. 45335). More on author: Fricke.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; non-migratory; depth range 0 - 15 m (Ref. 13227). Tropical
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.2 cm SL male/unsexed; (Ref. 13227); 2.9 cm SL (female)
(total): 12 - 15;
soft rays: 16 - 19. 9-12 spines in the second dorsal fin, 8-10 rays in the third dorsal fin, 17-20 anal fin rays, 32-37 + 1 lateral scale rows, 13-19 + 17-22 lateral line scales, two median mandibular pores, a black band on the caudal peduncle, about 9 basal dark spots on the female's anal fin, and a overall blackish coloration of the male.
Adults inhabit rock and coral reefs (Ref. 90102), from the surface to 15 m, including intertidal pools (Ref. 13227). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
