Rückenflossenstacheln (insgesamt): 4; Rückenflossenweichstrahlen (insgesamt): 7-9; Afterflossenstacheln 1; Afterflossenweichstrahlen: 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).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

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. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00274 - 0.02524), b=3.07 (2.82 - 3.32), 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
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Verwundbarkeit (Ref. 59153):  Low vulnerability (11 of 100) .
