There are a lot of strange-looking creatures in the ocean, but hammerheads have to be a top contender. How did evolution put them on the path to have a head shaped like *that*? Hammerheads have an electrosensory organ spread across their head (technically all sharks have it, but hammerheads take it to the next level). This organ, called the ampullae of Lorenzini, allows them to sense electric currents. Their heads function like metal detectors as they scour the sandy seabed looking for stingrays, their meal of choice. Their wide heads also help them pin stingrays down for easier eating. With eyes placed on either end of the “hammer”, hammerheads get to enjoy a nearly 360-degree field of view, handy for spotting food and avoiding predators. Here’s a fun fact: While hammerheads are considered fish, they give live birth to their young. We know what you’re thinking, but their babies are actually born with “normal” heads that grow into the hammer shape as they mature! Video by paulnickl...
