Etymology: Amblygobius: Greek, amblys = darkness + Latin gobius = gudgeon (Ref. 45335). More on author: Rüppell.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; depth range - 10 m (Ref. 100374), usually - m (Ref. ). Tropical; 22°C - 30°C (Ref. 27115)
Indo-West Pacific: Red Sea and East Africa south to Durban (South Africa), including most islands in the western Indian Ocean islands; Indonesia, Australia and South Pacific islands. Also known from Japan, Philippines (Ref. 2798) and Persian Gulf (Ref. 68964)
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm SL male/unsexed; (Ref. 2798)
Epibenthic and littoral, entering estuaries and lagoons (Ref. 4343). Usually seen in pairs, hovering a short distance above the substratum. Monogamous (Ref. 52884). t builds its burrow in sand or silty sand by moving out mouthfuls of sediment (Ref. 11441).

Bayesian length-weight: a=0.01023 (0.00475 - 0.02204), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.6 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
