The great white shark both frightens and fascinates. With its large jaws packed with around 300 razor-sharp teeth, it’s one of the world’s most formidable predators.

The bonnethead shark lives well in captivity, which has given researchers plenty of opportunity to learn more about it.

It’s not only … Read more
Whale sharks can grow to 60 feet long and have mouths easily big enough to swallow a human. Far from being vicious predators, however, whale sharks are gentle giants that drift around the ocean feeding on microscopic prey and the occasional fish. What do Whale Sharks Eat?
