The bluespotted ribbontail ray (Taeniura lymma) is found alone or in small groups mostly in shallow water over reef flats. It also has been observed around coral rubble and shipwreck debris at depths of 65’. It rarely buries itself completely in the substrate, and divers and snorkeleres will often detect it by its distinctive ribbon-like tail poking out from a crack or crevice beneath the coral. It is the most abundant of the inshore reef-dwelling rays. Being rather timid, the ribbontail ray will usually swim away frantically if approached or disturbed by divers. Unlike most other stingrays, its poisonous spines, often two in number, are located closer to the tip than the base of its tail. The sting causes minor injury. These rays reach about 2.5’ in length.
