Stingrays are oviparous, laying eggs inside a protective hard case that's commonly referred to as a "mermaid's purse". The embryos develop inside their cases for months before hatching. They are cartilaginous fish, closely related to sharks and rays.
baby stingray!!! What looks to be a pair of legs are called "claspers", or modified fins. Claspers are only found on males, for mating.. so these three dancing babies are males!The babies are actually milk-fed while inside the mother during gestation.
