Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 8; Raggi dorsali molli (totale) : 15; Spine anali: 2; Raggi anali molli: 16. This species is characterized by the following: D XIII,15; A II,16 (rarely II,15); pectoral rays usually 17 (rarely 16 or 18); tubed lateral line scales 15-18 (usually 16); gill rakers 6-7 + 15-17 = 21-24,(usually 23); body depth 1.9-2.0 in SL; color in life generally dark grey brown, also median fins; a large black spot on pectoral fin base that has a large triangular dorsal extension; upper half of eye with a fine, bluish white rim; adults usually with a small black spot near rear base of soft portion of dorsal fin, a remnant of an ocellus, which is prominent in juveniles (Ref. 75750).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Common on silt-affected coral reefs, in loose aggregations that apparently feed on zooplankton above the reef (Ref. 75750). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
