Sciaenidae (Drums or croakers)
Etymology: Argyrosomus: Greek, argyros = silvered, silver + Greek, soma = body (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; benthopelagic. Subtropical
Western Indian Ocean: known only from Durban Harbor, South Africa.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 23.0 cm SL male/unsexed; (Ref. 1008)
Dorsal spines (total): 11; Dorsal soft rays (total): 27 - 28; Anal spines: 2; Anal soft rays: 7. Strikingly contrasts with other Argyrosomus species by its short, beak-like snout and its concave dorsal profile. Also differs from its congeners by its large eyes (23.8-26.9% HL), narrow interorbital width (15.2-15.6% HL), and long pectoral (23.2-23.8% SL) and pelvic (22.4-23.3% SL) fins.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00280 - 0.01185), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.8 ±0.6 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 (18 of 100).
