Common Eagle Ray Fish
Eagle rays are aptly named, because their pectoral disc is much wider han it is long, so the fish appears to have wings. They are also (along with the manta rays; much more active swimmers than most other rays, ‘flying’ through the water by flapping their wings, and even leaping into the air. They use their flat, plate-like teeth to crush crustacean and mollusc shells. The common eagle ray has a venomous tail spine but is not regarded as dangerous. The huge spotted eagle ray (Aetobatus narinari), up to 3m (10ft) wide, is common worldwide in the tropics and subtropics, including waters off the southern and south-eastern USA.

Common StingRay Fish
Slightly more rounded in outline than skates and true rays , the common eastern Atlantic and Mediterranean stingray lives mostly in shallow water. One or sometimes two saw-toothed poisonous barbs, up to 35cm (14in) long, project from the top of its tail. If disturbed — perhaps by a diver or fisherman, or even by a bather stepping on the half-buried fish — it will lash with its tail and may stab or cut its victim seriously. Poison entering the wound from a gland at the base of the barb causes intense pain, but deaths are rare. However, a few people die worldwide each year from stingray stings, usually to the upper part of their body.
