Haller’s Round Stingray / Tennessee Aquarium

A new Haller’s Round Stingray arrived at the Tennessee Aquarium with a surprise of her own to share: she gave birth to a litter of five on 21 October, soon after her arrival. Each baby now measures about 8 cm, minus the tail, and could grow to be slightly larger than 30 cm in disk size as adults. Stingrays give birth to live young, which absorb nutrients from a yolk sac and then a special uterine milk before birth. Born fully developed, the babies are immediately able to swim and feed, requiring no parental care — via ZooBorns
