Etymology: Oxyurichthys: Greek, oxys = sharpen + Greek, oura = tail + Greek, ichthys = fish (Ref. 45335). More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; depth range 1 - 50 m (Ref. 37816). Tropical
Indo-West Pacific: Red Sea south to Natal, South Africa and east to the tropical west Pacific.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 48637)
soft rays: 13. Body brown with 7-8 vertical dark brown bars (Ref. 2798); characterized further by pale brownish grey body color with orange spots/bands on cheek and operculum; united pelvic fins, well developed frenum present; long and pointed caudal fin, nearly twice length of head; longitudinal scale series 75-80; ctenoid scales posteriorly to below middle of first dorsal fin, becoming cycloid anteriorly; scales absent on head, midline of nape and prepectoral area; low fleshy ridge on midline of nape; depth of body 5.6-6.5 in SL (Ref. 90102).
Occurs inshore (Ref. 4343), mud bottoms of estuaries and protected bays (Ref. 37816). Found on open flat bottom and large adults mostly seen at about 30 meters depth. Dives head first into the mud for safety (Ref. 48637). Hides in a burrow, but can dive into mud to escape predators (Ref. 11441).
