The common eastern Pacific stingray, angular rather than round, buried on shallow sand and sometimes in numbers.
To about 1 m across the disc, plain grey-brown, angular rather than round, with a row of small thorns along the midline and a long tail. It is the common stingray of eastern Pacific sand flats.
It buries with the eyes and spiracles showing and is often in groups on shallow sand in the Galapagos, sometimes in numbers large enough to cover the bottom. It carries a venomous barb near the tail base and uses it when trodden on, which in the Galapagos means when a person walks into the water from a beach. Shuffle rather than step.
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.
