Description
Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 8; Pectoral fin rays: 17-19, upper three rays partly free of membrane; Longitudinal scale series: 29-36; Predorsal scales: 10-19, reaching from above middle of preopercle nearly to interorbital space; Depth of body: 4.4-5.0 in SL; Body moderately elongate and compressed. Head subcylyndrical; Gill opening not extending anteriorly to a vertical through posterior margin of preopercle; Mental flap well developed, trapezoid, but not protruding posterolaterally; No flap-like projection at tip of anterior nostril; Anterior margin of tongue notched. Rounded caudal fin; Pelvic fins united medially; Frenum present, with no distinct projection at middle of posterior margin. Cheek and opercle without scales; Ctenoid body scales, becoming cycloid on abdomen, breast and nape; Depressed head, width greater than depth. Sensory canals and pores present on head; Longitudinal pattern of sensory papillae on cheek; Uniserial transverse row of sensory papillae just behind chin. Max. length: 12.0 cm TL. Depth range: 0 - 6 m.
Color
A pale yellowish-brown goby with a large irregular brown markings on the body, small pale blue spots on each scale forming rows along the sides, small blue spots on diorsal and caudal fins, and a broad yellowish margin on the dorsal fins.
Etymology
Bathygobius: from Greek, bathys = deep + from Latin, gobius = gudgeon.
fuscus: from Latin, fuscus = dark, dim, dimly lit, black, brown. Referring to its uniform liver-brown color in alcohol.
Original description: Gobius fuscus Rüppell, 1830 - Type locality: Red Sea.
Distribution
Red Sea; Indo-West Pacific: East Africa, Persian Gulf, Seychelles, Comoros, Madagascar and Mascarenes (La Réunion, Mauritius, Rodrigues), east to Wake Atoll, Marquesas Islands and Gambier Islands (French Polynesia), north to southern Korea and central Japan, south to Western Australia, Queensland (Australia), New Caledonia, Norfolk Island (Australia) and Tonga.
Biology
Occurs mostly in coastal areas. Also found in estuaries, tidal pool zones and often ascending into freshwater streams; Smaller species live between branches of corals where they exploit several crustacean groups. Feeds on crustaceans, fish and algae. Sometimes seen as fresh catches at markets. Benthic spawner.
