Short description Claves de identificación | Morfología | Morfometría

Radios blandos dorsales (total) : 43 - 44. Recognized by the black spot on the head. Males lack dorsal filaments but have a long extended ventral fin ray (Ref. 48636).

Found on sandy bottoms in shallow waters (Ref. 32211). Seen singly or in coastal sand slopes (Ref. 48636). Feed on zooplankton (Ref. 9137).

Estimates based on models

Preferred temperature (Ref. 123201): 17.9 - 28.1, mean 26.2 °C (based on 564 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.4 ±0.45 se; based on food items.

Generation time: 2.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

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