White-spotted, duck-billed, and usually going the other way.
To about 3 m across the disc, dark blue-grey above covered in white spots and rings, white below, with a long duck-like snout, angular wings and a whip tail several times the body length carrying one to five venomous spines at its base. Indo-Pacific fish were separated from the Atlantic Aetobatus narinari relatively recently, so older records here carry that name.
It digs molluscs and crustaceans out of sand with the snout and crushes them with plate-like teeth, and cruises along slope edges between feeding areas, often in small groups. It is wary and rarely allows a close approach; the working method is to stay low, stop, and let it pass. Recorded from about 5 to 50 m.
Ratings are per location: 1 means found on most dives that look for it, 5 means a handful of records. Where enough dives have been logged the figure is calculated from them; otherwise it is an editorial estimate, and says so. We publish habitat and destination, not the dive site.
