    About This Project

    I'm interested in how stingrays, with jaws made of cartilage, consume tough or stiff prey like insects, crabs, and mollusks. I use high-speed videography and measure bite forces to analyze how rays use their jaws to eat tough prey. These freshwater rays invaded South America 30+ million years ago and diversified to feed on a variety of prey. How does feeding specialization evolve and what does it look like?

    Blast off!
