stingray of the familyDasyatidae , found aroundcoral reef s in thetropical Indo-West Pacific from theRed Sea andEast Africa to theSolomon Islands north to southernJapan and south to northernAustralia , betweenlatitude s 32° N and 30° S.The bluespotted ribbontail ray is a colourful stingray with large bright blue spots on an oval, elongated disc and with blue longitudinal stripes on the tail. The snout is rounded and angular, the disc with broadly rounded outer corners, and stout tail, tapering and less than twice the body length when intact, with a broad lower caudal finfold reaching the tail tip. The disc has no large thorns but has small, flat
denticle s along the midback in adults. There is usually one medium-sized sting on the tail further back than in most stingrays.It migrates in groups into shallow sandy areas during the rising tide to feed on
mollusc s,worm s,shrimp s, andcrab s, dispersing on the falling tide to seek shelter in caves and under ledges. Rarely found buried under the sand. Small specimens are popular among marine aquarists, but it does not do well in aquaria.Coloration is grey-brown to yellow, olive-green or reddish brown with large bright blue spots dorsally, white ventrally.
