Short description Identification keys | Morphology | Morphometrics

Vertebrae: 118 - 135. This species is distinguished by the following set of characters: 2 infraorbital pores found at the postorbital area; median ventral groove on the snout absent; acute snout; rictus of mouth slightly posterior to a vertical line through the posterior margin of the eye; pointed conical teeth on upper jaw and vomer, arranged biserially on upper jaw, uniserially on vomer; dorsal-fin origin posterior to a vertical line through the anus, horizontal distance between the origin and the vertical line 13-55% HL; tail 54-58% TL; total vertebrae 118-135, predorsal 51-57 and preanal 47-52; mean vertebral formula (MVF) 53.9-50.0-128.6 (Ref. 92899).

Biology     Glossary (e.g. epibenthic)

Lives in loose sand and fine gravel (Ref. 1602). Benthic (Ref. 58302) and burrowing species found in inshore waters (Ref. 7300, 75154). Feeds on small fishes and crustaceans (Ref. 89972).

Estimates based on models

Preferred temperature (Ref. 115969): 24.9 - 29.2, mean 28.1 (based on 2563 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00076 (0.00029 - 0.00199), b=3.06 (2.83 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.7 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 to moderate vulnerability (28 of 100).
