Species often confused with {name}
Mangrove Whipray
Urogymnus granulatus
Key differences: Urogymnus granulatus (formerly Himantura granulata) is primarily a marine and estuarine species, though it can enter freshwater. It typically has a rougher dorsal surface due to the presence of small denticles, especially in adults, and often exhibits a more uniform coloration without the distinct mottling seen in U. dalyensis. U. dalyensis is almost exclusively freshwater.
Estuary Stingray
Hemitrygon fluviorum
Key differences: Hemitrygon fluviorum (formerly Dasyatis fluviorum) is also found in estuaries and lower freshwater reaches but generally has a more angular disc shape and a row of thorns along the midline of its back, which are absent in U. dalyensis. Its tail also typically has dorsal and ventral fin folds, which U. dalyensis lacks.
