Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 4 - 5; Vertebrae: 17 - 18. Fourth gill arch with filaments which are reduced in size compared to filaments in arches 2 and 3. Lateral-line scales: cheek 7; subopercular 5-8. Rostrum a short cone, usually tilted sharply upward. Disk strongly triangular-shaped with large, blunt, backward-sweeping subopercular spines. Bucklers on ventral surface of tail which are evenly distributed. Eyes directed laterally and slightly anteriorly; small mouth (Ref. 30695).

Estimates based on models

Preferred temperature (Ref. 123201): 14.1 - 22.7, mean 19 °C (based on 57 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01479 (0.00517 - 0.04233), b=2.93 (2.68 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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