Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 3; Dorsal soft rays (total): 135 - 137; Anal spines: 1; Anal soft rays: 97 - 101; Vertebrae: 156 - 170. Lateral line descending steeply from head and reaching close to ventral body margin; maxilla extending almost to a vertical through posterior margin of eye; subopercle large, elongated, anteriorly serrated, and fimbriated along posterior margin; first anal spine enlarged, dagger-shaped; and caudal peduncle vertebrae short and bearing neural spines (except ultimate centrum), the last four penultimate centra each bearing one long and two short neural spines on the middle of the dorsal zygapophyses (Ref. 50501). Lacks a caudal fin, the body tapering to a hairlike tail (Ref. 50501).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00052 (0.00022 - 0.00126), b=3.13 (2.93 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (38 of 100).
