Short description Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0; Anal soft rays: 55 - 62. Belly with about 29 scutes. Lower jaw projecting, its mouth pointing obliquely upward; no hypo-maxilla. Pectoral fin a little longer than head; dorsal fin origin nearer to caudal fin base than to vertical from pectoral fin base by 1 and 1/2 eye diameters (or behind midpoint of body by 2 and 1/4 eye diameter); anal fin long, its origin much nearer to snout tip than to caudal fin base.

Occurs in coastal waters, perhaps entering brackish water (Ref. 9336). Feeds mainly on small fishes (Ref. 9336).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00409 - 0.01408), b=2.97 (2.81 - 3.13), based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 4.2 ±0.73 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (19 of 100) .

Price category (Ref. 80766): Low.
