Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 8; Anal soft rays: 5; Vertebrae: 27 - 29. Distinguished from its congeners in possessing the following unique combination of characters: body plain brown, head dorsum plain brown; dorsal, caudal and anal fins red in life; absence of secondary rostrum; absence of postoral pouch; gill slit angular, subopercular groove present and continuous with pectoral-fin origin; snout broadly round when viewed dorsally; presence of sublacrymal groove; absence of scales on abdomen; 58-63 scales in lateral line; pelvic fin just reaching level of anal fin origin, adpressed dorsal fin not overlapping level of anal fin origin (Ref. 56228).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00617 (0.00268 - 0.01421), b=3.11 (2.91 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.3 ±0.1 se; based on size and trophs of closest relatives

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