Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 8; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 9; गुदा कांटा: 2; ऐनल सौफट रेज़: 8. This species is distinguished by the following characters: D VII-I,9; A II,8; pectoral rays 15 (occasionally 14); lateral-line scales 24; predorsal scales 3-4; developed gill rakers 4-5 + 18-19; serrated preopercular margin; finely serrated preopercular ridge; body depth 2.9-3.4 in SL; third and fourth dorsal spines are the longest. Colouration: in life pinkish, grading to pale yellow ventrally with a faint grey stripe on head at eye level, a large black spot at base of caudal fin, with a series of faint narrow dark bars on the lower side, and black outer edge on first dorsal fin (more pronounced in male); the peritoneum is pale with scattered melanophores; the outer surface of intestinal tract black (Ref. 114921).
Cross section: compressed.
This species occurs in aggregations, usually mixed with other apogonids. Hovers about
1-2 m above the bottom at depths of 18-30 m (Ref. 114921).
