Description

You may have seen these skate cases lying on the beach while looking for shells. These are the egg cases of skates and sharks. Skates are animals that look very much like stingrays, but stingrays and some sharks give live birth rather than laying eggs. The cases come in a variety of different forms and each case typically contains only one embryo. The exceptions are the Big Skate and the Mottled Skate, which lay eggs that contain up to 7 embryos [3].
