A small round ray mottled in yellow and brown, part-buried on sand in shallow water. Common at Blue Heron Bridge.
To about 40 cm, a small round ray mottled in yellow, brown and cream, on shallow sand in Florida and through the Caribbean. It buries with only the eyes and the spiracles showing and it is common at Blue Heron Bridge, which is a site people walk into.
The tail carries a venomous serrated barb. It is a defensive weapon and it is used when the animal is trodden on, which is the whole of the risk: shuffle rather than step in shallow sand, and look at the ground before kneeling on it. A barb wound is a deep puncture as well as a sting, and it needs cleaning and medical attention as well as hot water for the pain.
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.
