For the first time, researchers recorded a leopard shark (Stegostoma tigrinum) mating event. Also known as a zebra shark, the leopard shark lives near the coral reefs and sandy ocean shelves of the tropical Indo-Pacific. A full-grown leopard shark averages about eight feet long and prefers a diet of mostly shelled molluscs, crustaceans, and small fish. For environmentalists, understanding leopard shark mating habits could offer valuable information for boosting the population and saving the animals from further harm. Although arguably a bit voyeuristic, the documentation marks a major moment in leopard shark conservation efforts, especially for a species that is mostly solitary.
