Description synthétique Clés d'identification | Morphologie | Morphométrie

Distinguished by the following characteristics: general body color is light grey-brown, typically have areas of very bright iridescent blue and/or yellow; body is laterally compressed; large, nearly vertical mouth; completely scaled body; first dorsal with VII spines; ventral fins are united (Ref. 92840).

Adults inhabit mangrove streams with very fine silt-mud substrate (Ref. 92840) with salinity ranging from 0.0 to 36.6 ppt (Ref. 97140).

Estimates based on models

Preferred temperature (Ref. 123201): 22.9 - 25.4, mean 24 °C (based on 218 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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

Microgobius gulosus (Girard, 1858)
