Bull sharks are famous for their ability to thrive in saltwater, freshwater, and everything in between. Not every shark can do this—but the bold, adaptable bull shark can! They’ve been spotted in rivers hundreds of miles from the ocean, and this week we’ll investigate how that’s possible. There’s no better way to learn about anatomy than through a dissection. We’ll play plenty of Sharks and Minnows, scour the beach for shark teeth, and experiment with salinity—bringing our refractometers wherever we go! And you better bull-ieve we’ve got the biggest, craziest, wildest obstacle course lined up to mimic traveling upstream. Be sure to bring your water bottle this week, because we’re going to have some seriously salty fun!
