The round stingray (Urobatis halleri) or Haller's round ray and Little round stingray is a species of round ray, family Urotrygonidae, found in the coastal waters of the tropical and subtropical parts of the northeastern Pacific Ocean. It is a small, common ray that feeds mostly on benthic invertebrates. On the beaches of southern California, it is responsible for numerous injuries to bathers, who are stung when they accidentally step on the fish. The wound caused by its venomous spine can be painful, but is non-fatal. Wikipedia →
