Short description Morphology | Morphometrics

Spiny dorsal-fin membrane very dark between first and second spines, slightly to much less darker between second and third spines, and pale between third and fifth spines. Outline of head between base of first dorsal-fin spine and eyes somewhat convex in front of spine and then straight or slightly concave over eye (Ref 9804).

Inhabits sandy and muddy flat in coastal areas. Feeds on benthic invertebrates. Marketed fresh.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.7578 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.5 ±0.37 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100) .

Price category (Ref. 80766): Unknown.
