Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 4; Dorsal soft rays (total): 7 - 9; Anal spines: 1; Anal soft rays: 6 - 8. Head flat, slightly depressed. Short and flat leathery barbel in chin, tubercles absent. Body color variable depending on habitat (Ref. 33724). Distinguished further from its congeners by the following characters: body covered with numerous, densely-set thorny granules; 3 dark blotches along midline of back and flank; head and back with dark dots, sometimes on dorsal, pectoral and caudal (Ref. 59043).
Prefers brackish and slightly saline zones in deltas and estuaries; in summer inhabits shallow coastal waters (0.5-20 m) and shallow deltas; in winter, moves to deeper areas (up to 60-70 m). Spawns after first winter. Feeds mostly on molluscs and crustaceans (Ref.59043).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.3 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 vulnerability (10 of 100).
