The Aetobatidae family includes the leopard rays, which were previously classified under Myliobatidae family. They are distinguished by their long, protruding snouts, slender bodies and characteristic spotted patterns. These powerful swimmers inhabit open water and primarily feed on mollusks and crustaceans, which they crush using strong dental plates.

The Mobulidae family includes manta rays and devil rays, some of the largest rays in the world. They are characterized by their broad, wing-like pectoral fins, forward-facing cephalic lobes, and their filter-feeding behavior, which allows them to consume plankton. Mostly pelagic, these species live in open water and are capable of traveling long distances
