Some studies suggest that the female must undergo this process up to 4 times before fertilization is complete and gestation begins.

The spotted eagle ray is oviparous. The eggs mature and hatch inside the mother, but they do not feed on her. The young in gestation feed on the yolk of the eggs until they are mature, hatch from the egg, and the female bears them.
