Summertime in San Diego means the return of leopard sharks to La Jolla Shores. Contrary to popular belief, these sharks – 97% of which are pregnant females – are not giving birth or mating during their stay. Join Andy Nosal, a Scripps PhD student who studies local leopards, to find out what scientists really think is going on. Discover what gadgets Nosal uses to track the sharks and learn what makes La Jolla the animals' preferred hang out. Find out why this shark population is particularly vulnerable and how the local no-take marine reserve protects it. (#24000)
