Etymology: Psammogobius: Greek, psammos = sand + Latin, gobius = gudgeon (Ref. 45335). More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; benthopelagic; amphidromous (Ref. 51243); depth range - 3 m (Ref. 86942), usually - m (Ref. ). Tropical; 22°C - 28°C (Ref. 13614)
Indo-Pacific: south to East London, South Africa (Ref. 2798). Western Central Pacific: Guam (Ref. 35720). Often confused with the more common Glossogobius giuris.

Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL male/unsexed; (Ref. 4343)

Estimates based on models
Preferred temperature (Ref. 115969
): 24.2 - 29.3, mean 28.4 °C (based on 2860 cells).
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00606 - 0.01727), b=3.04 (2.90 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.2 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.).
Vulnerability (Ref. 59153
): Low vulnerability (23 of 100) .
