The basking shark looks intimidating. It’s the second largest of all fish—it’s 25 feet or longer and can weigh 10,000 pounds. And it can open its jaw a yard wide—wide enough to swallow a person. Yet the shark is a gentle giant. It cruises through the ocean at a leisurely two or three miles per hour, filtering tiny organisms from the water—nothing for swimmers to fear.
Sometimes scientific discoveries answer questions scientists have wondered about for years, but more often, a discovery simply raises dozens of new questions to explore. For example, why on earth do dozens of female great hammerhead sharks gather at two atolls in French Polynesia around the full moon each summer? While we don’t know the reason right now, the observation opens the door to more research to uncover the mysteries of this severely endangered species.
