Noteworthy media coverage: CNN, National Geographic, Gizmodo

As many of our readers prepare for a romantic evening with their special someone (or a Single’s Awareness Day celebration with friends), I invite you to take a few minutes and learn how our toothy friends in the ocean do it. And by “do it”, I mean “do it”. Here are 10 things you might not have known about shark sex.

1) Sharks have external reproductive organs. A male shark has reproductive organs called “claspers” (yes, there are two of them), and females have a “cloaca”. As I regularly tell the high school students who join us for shark research trips, even if you don’t have a degree in marine biology, you’ll quickly recognize what you’re looking at.
