A large devil ray of offshore seamounts with long sickle-shaped wings, which dives below a thousand metres and surfaces to be cleaned.
To about 3.7 m across the disc, olive-brown above with a paler back margin, and long sickle-shaped wings. It is much larger than Munk’s devil ray and it is separated from a manta by the underslung mouth.
It occurs around offshore seamounts and it dives deep — recorded below a thousand metres — surfacing and visiting cleaning stations, which is when it is seen. At the Galapagos and Cocos it is an occasional animal at a cleaning station in mid-water. It has no sting.
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.
