Common name. Arabian freshwater goby.
Diagnosis. Distinguished from sympatric Glossogobius by: ● upper lip projecting beyond lower lip / ● caudal rounded. Size up to 200 mm SL.
Distribution. Oman, UAE, Yemen, southern Iran, and Pakistan.
Habitat. Lower and middle parts of streams that flow into sea at least once every few years. Occupies soft bottoms with sand, silt or organic material. Also on soft sea bottoms, in estuaries, mangroves and coastal lagoons.
Biology. No data. Other species in this genus are amphidromous and spawn in freshwater. Male guard eggs. Larvae are pelagic and must drift into estuaries or ocean. Juveniles migrate to freshwater to grow into adults and spawn. No resident freshwater populations known, but individuals can live for many years, and larvae may only reach sea in years of heavy flooding. Individuals often bury themselves in soft sediment. Marine and brackish water-only populations are expected to occur along coastlines.
Conservation status. LC.
Remarks. Previously identified as Awaous aeneofuscus , a species known from the East African coast, possibly as far north as Socotra ( Yemen). The distribution boundary between the two species is unknown, but individuals from Wadi Masila in Hadhramaut are identified as
Wadi Shab in Oman is the habitat of Awaous jayakari and Glossogobius tenuiformis .
A. jayakari . Individuals from Socotra have yet to be identified and are provisionally included under A. jayakari . Awaous jayakari differs from A. aeneofuscus in having a pectoral base that is scaleless or has only 1–3 scales
in adults (vs. pectoral base that is usually completely covered with scales).
