Apparently restricted to eastern Australia (Ref. 87957); distribution to be resolved when new studies or publications are received.
Environment: milieu / climate zone / depth range / distribution range
Οικολογία
Θαλασσινό(ά); εύρος βάθους 200 - 860 m (Ref. 26346). Deep-water; 34°N - 46°S
Western Pacific: eastern Australasia to New Zealand.
Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 46.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 6871); 39.0 cm TL (female)
Ραχιαίες άκανθες (συνολικά) : 2; Εδρικές άκανθες: 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).
Probably demersal (Ref. 31367) on upper continental slopes (Ref. 6871). Ovoviviparous (Ref. 205), size at birth about 15 cm (Ref. 6871).
