Short description Identification keys | Morphology | Morphometrics

Second dorsal-fin spine more than 1/2 length of first dorsal-fin spine. Anal-fin base about 2 times in soft dorsal-fin base. Scales with an anterior to posterior series of high, thin, distally emarginated vertical ridges (Ref 9804).

Occurs in coastal and estuarine waters, on sandy or muddy flats to depths of usually 60 m, Ref. 48637. Feeds on benthic invertebrates. Sold fresh in markets.

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29, mean 28 °C (based on 1840 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01259 (0.00691 - 0.02294), b=2.88 (2.71 - 3.05), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.5 ±0.20 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).

Price category (Ref. 80766): Unknown.
