Brevitrygon
Brevitrygon is a genus of stingrays in the family Dasyatidae. It contains two species, both endemic to the Indo-Pacific region. They are characterized by their relatively short and broad pectoral fins, and the presence of a prominent nuchal fold (a fold of skin at the back of the head). The name Brevitrygon is derived from the Latin words “brevis” (short) and “trygon” (stingray), referring to their distinctive short pectoral fins.
Common Names
Common names for members of this genus include "shortfin stingrays" and "fantail stingrays".
Characteristics
Brevitrygon species are relatively small stingrays, with a maximum disc width of about 60 cm (24 in). They have a distinctive diamond-shaped disc, with a short, broad snout and a pair of prominent, well-developed dorsal fins. Their tails are relatively short and slender, with a prominent venomous spine located near the base. The color pattern varies depending on the species.
Environments
Brevitrygon species inhabit shallow coastal waters, including sandy bottoms, seagrass beds, and coral reefs. They are typically found in tropical and subtropical waters, at depths of up to 100 m (330 ft).
