Why Hammerhead Sharks are So Sick (ft. Bertie Gregory) | Lindsay Nikole

Hammerheads aren't just weird-looking their hammer-shaped head is one of evolution's most brilliant designs. Discover how their cephalofoil gives them a supercharged electroreception system that can detect prey buried in sand across a wider field than any other shark. But these iconic predators are in serious trouble. Wildlife filmmaker Bertie Gregory (National Geographic, Emmy winner) joins the channel fresh from filming scalloped hammerheads off the Baja Peninsula in Mexico once a hammerhead mecca, now a conservation battleground. Plus, meet Chocolate Chip, a massive oceanic manta ray with a bubble bath addiction, and find out why there might actually be hope for one of the ocean's most misunderstood apex predators. A huge thank you to NatGeo and Bertie for making this possible!
