Description

Disc oval, trunk robust, width about 0.8 times length; snout bluntly rounded, tip not pointed; anterior margin slightly convex. Tail rather broadbased, depressed, relatively short (about 1.5 times disc width when undamaged); tapering rapidly to sting, slightly compressed beyond sting; mostly with 2 stings located well behind pelvics; ventral cutaneous fold deep, long, extending to tail tip; dorsal midline with very low fleshy ridge. Eyes moderately large, length of eye and spiracle about 1/2 preorbital snout length; interorbital space narrow. Mouth small, 2 large central papillae on floor; labial furrows deep, lower lip and internasal flap with prominent papillae. Internasal flap narrow, elongate; posterior margin deeply concave with prominent fringe; lower jaw slightly concave near symphysis; nostrils slender, narrow. Pelvic fins moderately elongate, slender. Disc smooth, except for patch of small, widely spaced thorns in nuchal area; sometimes with a short row posteriorly.
Colour: dorsal surface brownish or yellowish brown with large blue spots (some almost 1/2 eye diameter); tail without spots, usually with long midlateral blue stripes before sting, bluish posteriorly; ventral surface mostly uniformly white.

Size

Maximum total length about 70 cm; maximum disc width 30 cm.

Ecology

Possibly the most abundant stingray found in coral reef habitats of the area. Inshore, mostly occurring shallower than 20 m. Molluscs, worms, shrimps, and crabs are major prey items. Feeds over shallow sandy flats during the rising tide then disperses on the falling tide to seek shelter in caves and under ledges.

Importance

Important commercial species taken mainly by traditional fishermen.

Distribution

Widespread in the Indo-West Pacific, from southern Africa to the Solomon Islands (including the Red Sea). Not recorded from the Japanese Archipelago or Taiwan Province of China.
