Round stingray

The Round stingray (Urobatis halleri) is a small, disk-shaped marine fish notable for its round pectoral fin disc and long, slender tail equipped with a venomous spine. Its coloration ranges from olive to dark brown, often featuring spots or mottling that helps it blend into sandy or muddy bottoms. Native to the shallow coastal waters of the eastern Pacific, from California, USA, to the Gulf of California, Mexico, this species thrives in bays, estuaries, and near rocky reefs. Despite its interesting appearance and behavior, the Round stingray is not commonly kept in the aquarium hobby, partly due to its specific habitat requirements and the potential danger posed by its venomous spine.
