Eastern Tasmania and the Cascade Plateau, to off southwestern Tasmania and possibly north to off Portland, Victoria. Elsewhere the species occurs in New Zealand and off Saint Paul Island. Adults of this relatively rare species occur near the bottom in deep waters, while subadults are found near the surface over deep water, and juveniles occur inshore, usually above 50 m.

Body a compressed elongate oval of moderate depth (32-44% SL); caudal peduncle short and compressed. Head small (22-36% SL), compressed; snout bluntly rounded, slightly overhanging mouth; eyes of moderate size (20-22% HL); mouth of moderate size, maxillae reaching well below eyes, slightly receding; teeth fine, single row in each jaw.  Pyloric caeca numerous, simple and finger like. 
Scales very small and easily dislodged; lateral line more or less following profile of back. Numerous small pores on head, especially on snout and around eyes and mouth; broad well defined band of pores along trunk adjacent to dorsal and anal fins.
Single elongate, very low, fleshy dorsal fin with short soft spines grading into branched rays, origin above pectoral fin bases, outer margin parallel to that of trunk; anal fin low, fleshy, rather elongate, margin slightly convex; caudal fin moderately forked, tips pointed. Pectoral fins small, paddle-shaped. Pelvic fins thoracic, very small, almost vestigial.
