परिपक्व अवधि: Lm? range ? - ? cm Max length : 5.4 cm SL पुल्लिंग / अलिंग; (Ref. 117117)
संक्षिप्त वर्णन पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 13; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 10 - 12; गुदा कांटा: 2; ऐनल सौफट रेज़: 10 - 12; जानवरों की रीड़ का जोड़: 26. This species is distinguished by the following characters: D XIII,10-12 (usually 11); A II,10-12 (usually 11); pectoral-fin rays 17-19 (rarely 19); tubed lateral-line scales 16-19 (usually 17-18); total gill rakers on first arch 21-23 (usually 21-22); body depth 2.2-2.4 in SL; ventral margin of suborbital exposed (i.e. not hidden by scales); middle fin rays of dorsal and anal fins filamentous; dorsal and ventral margins of caudal fin filamentous; mainly dark brown in life except pale posteriormost parts of dorsal and anal fins and pale central portion of caudal fin; dark margins of caudal fin restricted to proximal half of fin; small dark spot at upper pectoral-fin base, but not extending into axil of fin (Ref. 117117). Body shape (shape guide): fusiform / normal; Cross section: compressed.
This species is generally associated with rocky substrates with ample crevices and coral formations, utilized for shelter. These are captured from about 1-10 m, with considerable tidal fluctuation (10+ m), especially along the Kimberley coast. Usually in large aggregations, which feed well above the bottom on zooplankton (Ref. 117117)..
