Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8 - 10; Anal spines: 1; Anal soft rays: 7 - 10. Distinguished by its usually scaled breast and rear edge of anterior pelvic membrane with minute projections (Ref. 59043).

Found inshore, over sand. Enters brackish and hyper-saline waters. Feeds on small crustaceans and chironomid larvae (Ref. 4343).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Males clean the insides of bivalve shells and cover the outside with sand in preparation for the eggs that will be deposited by the female (Ref. 46373). Nesting males exhibit breeding colouration with four dark bars across side, a blue spot on the first dorsal fin and dark coloration on pelvic fins and edge of anal fin (Ref. 4696). Males defend the nest, cleaning and fanning the eggs until hatching (Ref. 27118).

Estimates based on models

Preferred temperature (Ref. 115969): 10.3 - 17.3, mean 15.1 (based on 59 cells).

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

Bayesian length-weight: a=0.00741 (0.00568 - 0.00968), b=3.06 (3.02 - 3.10), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=1; Assuming fec < 10,000).

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