Alatina
Alatina is a genus of stingrays in the family Myliobatidae. These rays are commonly known as whiprays or thresher rays due to their long, whip-like tails. The genus includes 11 recognized species, distributed throughout tropical and subtropical waters worldwide.
Characteristics
Alatina rays are characterized by their flattened bodies, large pectoral fins that fuse with their heads, and long, slender tails that can be more than twice the length of their bodies. Unlike most other stingrays, Alatina rays lack a dorsal fin. They possess a single, venomous spine located on the dorsal surface of their tail near the base. This spine can inflict painful wounds and is used for defense. The color of Alatina rays varies depending on the species, but most are a mottled brown or gray with darker markings.
Environment
Alatina rays are found in a variety of marine habitats, including coastal waters, estuaries, and the open ocean. They prefer warm, shallow waters and are often seen near the seabed or swimming in mid-water. These rays are carnivorous and feed primarily on fish, crustaceans, and mollusks.
