Biology

The ocellate river stingray is often found lying still, buried in the sandy sediment at the bottom of a stream, particularly during the warmest part of the day (2) (5). Like all stingrays, the females of this species produce eggs, but these develop inside the female. The young hatch inside the female and are then 'born' live after a gestation period of no more than three months (5) (6). The litter size of the ocellate river stingray varies massively, from 3 to 21 young (2). Sexual maturity is reached at around three years of age, when the stingray measures between 30 and 35 centimetres across (2). Initially after birth, the ocellate river stingray feeds on plankton, but as it grows, the diet expands to also include small molluscs, crustaceans and the larvae of aquatic insects, while larger adults also eat certain catfish (those belonging to the family Loricaridae) (2). The ocellate has relatively few predators, except for some larger fish and caiman (3).
