It wasn't until 1976 that the megamouth shark finally revealed itself to the world. Since then, the Florida Museum of Natural History reports that Megachroma pelagios has been spotted only 41 times. These hulking sharks grow to around 17 feet (5.18 meters) long, but their feeding habits shouldn't cause any alarm. Like the enormous whale shark, the megamouth is a filter feeder that grazes on plankton. As its name implies, this shark species has a notably large jaw, with the corners of its mouth extending back farther than its eyes. The 50 rows of teeth that line the inside are mostly useless, however. After all, it doesn't take much munching power to plow through plankton.
