The Whitespotted Eagle Ray has an angular shaped disc with white spots on the upper surface. The species grows to at least 3.5 m disc width and 8.8 m in length.
The Whitespotted Eagle Ray has an angular shaped disc with white spots on the upper surface. The snout can vary in shape from spade-like in juveniles to pointed in large individuals (P. Last, CSIRO. pers. comm.). The whip-like tail has 2-6 spines.
Many references refer to this species as Aetobatus narinari. The work of White and coauthors (see References) showned that A. ocellatus has a longer tail and other morphometric differences. The major difference is in the background colouration of the dorsal surface; A. ocellatus is "a dark greenish, greyish to amost blackish (sometimes with a pink tinge)", whereas A. narinari is "much paler, medium yellowish brownish (fawn)"
The Whitespotted Eagle Ray occurs coastal waters.
The species occurs in tropical waters of the east-Indo-west-central Pacific. In Australia it is known from central coast of Western Australia, around the tropical north of the country and south to the central coast of New South Wales.
