Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 7; Anal spines: 1; Anal soft rays: 6 - 7. This small and strongly sexually dichromatic specis is distinguished by the following characters: D2 I,7; A I,6-7; pectoral rays 13-16; segmented caudal rays 16 in 9/7 pattern; lateral scales 25-28; transverse scale count 8-9; predorsal scales 6-8; snout is short and slightly pointed; opercle with 3 rows of cycloid scales, cheek no scales; shoulder girdle has a smooth edge or low angled bony flange; tongue is short, its tip blunt to bluntly rounded; outer row of teeth in upper jaw slender, slightly curved and pointed (may be slightly flattened). Colouration: males with a narrow black line along mid-side of body and a dense black rounded spot at upper base of caudal fin; females with broken dark brown line and an inistinct black spot at upper base of caudal fin (Ref. 126575).
Inhabits shallow-water estuarine to marine, found in mangrove creeks and muddy rocky reefs, at depths of 0-2 m and typically occurs with Pseudogobius aquilonius (Ref. 126575).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.0 ±0.4 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.
