Bull SharkMarch 01, 2014 – Bull sharks are the most dangerous sharks in the world, according to many experts. This is because they're an aggressive species of shark, and they tend to hunt in waters where people often swim: along tropical shorelines. Bull sharks live throughout the world, in shallow, warm ocean waters. They've been known to swim up into freshwater rivers. Humans are not part of a bull shark's normal prey. Bull sharks will eat almost anything, but their diet consists mainly of fish. They also sometimes eat dolphins and sea turtles. Bull sharks even eat other sharks. They hunt during the day and at night. Sharks must keep salt in their bodies to survive, and most can live only in salt water. But bull sharks have developed special adaptations—the way their kidneys function and special glands near their tails—that help them keep salt in their bodies even when they're in freshwater. Scientists are still studying these sharks to figure out why they developed this unusual ability.

Hammerhead SharkMarch 01, 2014 – This shark's unusual name comes from the unusual shape of its head, an amazing piece of anatomy built to maximize the fish's ability to find its favorite meal: stingrays. A hammerhead shark uses its wide head to trap stingrays by pinning them to the seafloor. The shark's eye placement, on each end of its very wide head, allows it to scan more area more quickly than other sharks can. The hammerhead also has special sensors across its head that helps it scan for food in the ocean. Living creatures' bodies give off electrical signals, which are picked up by sensors on the prowling hammerhead. The shark hunts alone, and can find stingrays that hide under the sand on the seafloor. Hammerheads also eat bony fishes, crabs, squid, lobsters, and other sea creatures. The upper sides of these fish are grayish-brown or olive-green and they have white bellies. They have very impressive triangular, serrated teeth—like the edge of a saw's blade. Hammerheads' mouths are on the underside of their heads. Unlike many fish, hammerheads do not lay eggs. A female gives birth to live young. One litter can range from six to about 50 pups. When a hammerhead pup is born, its head is more rounded than its parents'. There have been very few recorded attacks on people by the great hammerhead.
