This colourful stingray is immediately recognisable by the large, bright, iridescent blue spots that adorn its oval, elongated body (3) (4). Distinctive blue stripes also run along either side of the tail, which is equipped with one or two sharp venomous spines at the tip, used by the ray to fend off predators (5). Indeed, the brightly-coloured skin acts as 'warning colouration' to alert other animals that it is venomous (6). The snout is rounded and the mouth is found on the underside of the body, along with the gills (5), perfect for scooping up animals hiding in the sand (6). Two plates exist within the mouth that are adapted for crushing the shells of crabs, prawns and molluscs (5). The upper surface of the body disc is grey-brown to yellow, olive-green or reddish brown, while the underside is white (3). Thus, when viewed from below the white belly blends in with the sunny waters above and when viewed from above, the dark, mottled back blends in with the dark ocean floor below (6).
