Etymology: Enneapterygius: Greek, ennea = nine times + Greek, pterygion = little fin (Ref. 45335). More on author: Peters.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 8 m (Ref. 27223). Tropical
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.0 cm SL male/unsexed; (Ref. 27223)
(total): 13 - 16;
soft rays: 15 - 17. Pectoral-fin rays15, at least some branched; caudal peduncle without distinctive bar or marking; body without well defined bars; body, head and fins of males densely and evenly covered with melanophores, lower half of head generally darker than upper, in immature males and females less densely covered with melanophores sometimes showing indistinct oblique bars on body and anal fin; supratemporal sensory canal C-shaped, running in a curve in front of the first dorsal-fin spine; single symphysial mandibular pore present; no labial folds.
Adults occur in tide pools; in shallow water on beach rock, brown algae and coralline algae. Apparently associated with coralline rocky shore or reef flat (Ref. 27223). 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).
