Xingu River stingray

Fertilization in this stingray is internal and occurs through a clasper, an appendage found in males used to transfer sperm into the female’s cloaca.

After fertilization, the eggs of the Xingu River stingray develop inside the female’s reproductive system.

This species is ovoviviparous, meaning the eggs hatch inside the female, and the young are born fully formed. Gestation lasts approximately 9 to 12 weeks in the wild but may be shorter in captivity. Litters typically range from 6 to 8 offspring.
