Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 6; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 9 - 10; गुदा कांटा: 3; ऐनल सौफट रेज़: 38 - 45; जानवरों की रीड़ का जोड़: 25. This species is distinguished by the following characters: a yellow or yellowish dorsal fin with a black, distal margin along its full length, broadest on anterior rays (pupil-diameter width), gradually narrowing posteriorly, and the last ray with only a black tip; differs from its congeners by having large, deciduous cycloid scales on the flank; pectoral-fin base with a dark, oblong spot; anal fin with a dark margin along its length; 38-45 segmented anal-fin rays; 56-65 lateral-line scales; 31-35 total gill rakers on the first arch (Ref. 95447).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Collected with ichthyocide on coral or rocky reefs at depths less than 10 m in areas with ledges, caves, and surge channels (Ref. 95447).
