Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 14 - 16; Anal soft rays: 24 - 25. Differs from all other members of the family by its peculiar duck-bill, overhanging upper jaw, eyes protruding above dorsal profile of head and visible from below. Other diagnostic characters include 14-16 rays in dorsal fin and about 75 scales in lateral row (Ref. 26747).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Eggs are carried, protected in a body cavity by the pelvics, until hatching.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
