Taxonomic Remarks
Apparently restricted to eastern Australia (Ref. 87957); distribution to be resolved when new studies or publications are received.
पर्यावरण: पर्यावरण / जलवायु क्षेत्र / गहराई सीमा / वितरण सीमा
पारिस्थितिकी
समुद्री pelagic-oceanic; गहराई सीमा 200 - 860 m (Ref. 26346). Deep-water; 34°N - 46°S

आकार / वज़न / आयु
परिपक्व अवधि: Lm ?  range ? - ? cm
Max length : 46.0 cm TL पुल्लिंग / अलिंग; (Ref. 6871); 39.0 cm TL (female)
पृष्ठीय रीढ़ (सम्पूर्ण) : 2; गुदा कांटा: 0. Light brown above, black below, with a pale stripe on side and a black streak above and behind pelvic fins; belly luminous (Ref. 26346). Small and slender, with a moderately elongate caudal peduncle and with flank denticles mostly arranged in regular rows. The base of the pelvic flank markings is inserted in advance of the origin of the second dorsal-fin spine, the anterior branch is shorter than the posterior branch, and the caudal marking is longer than the precaudal marking (Ref. 6871).
Body shape (shape guide): elongated.
Probably demersal (Ref. 31367) on upper continental slopes (Ref. 6871). Ovoviviparous (Ref. 205), size at birth about 15 cm (Ref. 6871).
