The Gestation period for Hystrix is longer than with most Potamotrygon however to have the pups days apart seems a little strange....Wimm,can you still see movement?
Really hope things go well for you.
i had a motoro give birth to 3 pups one day and the rest of the pups about 2 weeks later. not sure why this happened but all the pups were healthy and survived
im sure it has something to do with them having 2 uterus.
