Sharks are somewhat notorious for their sense of smell and ability to sniff out prey deep in the ocean. There’s that persistent myth that sharks can smell a drop of human blood from a mile away. But that’s not exactly true. While sharks can smell human blood, they are more interested in sniffing out what’s for dinner: other fish, crustaceans, and molluscs. Ocean currents also play a role in how far a scent can travel. However, shark noses are just as powerful as any other fish in the sea.
SciFri producer Kathleen Davis talks with Dr. Lauren Simonitis, a National Science Foundation postdoctoral fellow in biology at University of Washington and Florida Atlantic University, about her shark nose research, and what questions remain about shark snoots.
Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
