Morphology | Morphometrics
soft rays: 51 - 56. Body deep (55-60% SL). Snout extended into a hook-like process projecting downwards in front of small, oblique mouth. Scales ctenoid, very small, rather firmly attached on both sides. Pectoral fin rays on right side 11-13, left 9-12. Pelvic fin rays on right side 7, left 4. Caudal fin rays 14 (Ref. 33839).
Occurs in sandy regions of bays and offshore areas. Flesh of very high quality but individuals taken are not often sufficiently large to make preparation worthwhile (Ref. 33839).
