Etymology: Amblygobius: Greek, amblys = darkness + Latin gobius = gudgeon (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 30 m (Ref. 86942). Tropical; 35°N - 28°S, 32°E - 143°W
Western Indian Ocean: Maldives (Ref. 30829) and the Red Sea and Arabian Gulf (Ref. 11441). Pacific Ocean: Philippines to the Tuamoto Islands, north to Yaeyama Islands, south to Rowley Shoals, southern Great Barrier Reef and Rapa; Guam and Kapingamarangi in Micronesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 48637)
soft rays: 13 - 15. Characterized by having overall pale grey body color; head and body with pink stripes, most intense on head; dorsal fin base with row of 8-9 dark spots; first and second dorsal fin equal in height; slightly pointed caudal fin; longitudinal scale series 63-66; cycloid scales; head without scales; depth of body 4.7-6.4 in SL (Ref. 90102).
Solitary or in pairs (Ref. 90102). Common in areas with fine sand to muddy bottoms at the bases of inner lagoon and coastal reefs. Monogamous (Ref. 52884, 48637). Feeds on small invertebrates and organic matter (Ref. 89972).
