A whale shark has never eaten a person
Whale sharks rarely even notice humans, let alone eat us. They don't eat anything larger than small fish. While they do have 300 rows of teeth in their giant mouths, whale sharks don't use them for eating. Whale sharks are filter feeders, like baleen whales.Megalodon is NOT alive today, it went extinct around 3.5 million years ago. Go to the Megalodon Shark Page to learn the real facts about the largest shark to ever live, including the actual research about it's extinction.

The blue whale is the biggest animal in the world. The elephant is the biggest on land. And the whale shark is the biggest fish in the sea.
When they see an aggressive shark, they immediately attack it with the whole pod. This is why sharks avoid pods with many dolphins. The dolphins will slam their snouts into the soft stomach of the shark which leads to serious internal trauma. They also use their snouts to hit the gills of the shark.
Dolphins and sharks both have dorsal fins on their backs, two pectoral fins on their sides, and a tail. Sharks' tail fins are vertical and they use them in a side-to-side motion to swim, while dolphins' tails are horizontal and they use them in an up-and-down motion to swim.
Both sharks and dolphins generally have what is called countershading where their bellies are lighter than their backs, which is a helpful way to blend in to the marine environment. Dolphins and sharks both have dorsal fins on their backs, two pectoral fins on their sides, and a tail.
Despite occasional reports of whales scooping people into their mouths, it's incredibly rare—and for all but one species, swallowing a human is physically impossible. On Friday, a lobster diver made headlines when he described miraculously surviving being “swallowed†by a humpback whale off Cape Cod, Massachusetts.
Fins.. sharks have 2 fins that break the surface; the dorsal and the caudal, dolphins have just one.
Shark-dolphin hybrids are impossible. It's true that sharks and dolphins look similar in many ways, but that's because they are a product of convergent evolution, where two genetically distant animals who live similar lifestyles start to look and act in similar ways. But sharks are fish and dolphins are mammals.
Large sharks prey on dolphins, they particularly target very young calves and sick adult dolphins as these are the weakest and most vulnerable individuals. Orcas will even attack and kill great white sharks just to eat their livers which are a high energy food source. A great white shark in the Gulf of Maine.
Sharks are solitary predators, whereas dolphins travel in groups called pods. Whenever a member of the group is in danger from a shark, the rest of the pod rushes in to defend their buddy. Dolphins have even been known to protect humans in danger of sharks.

Sharks are fish. They live in water, and use their gills to filter oxygen from the water. Sharks are a special type of fish known because their body is made out of cartilage instead of bones like other fish.
First thing's first: all dolphins are whales, but not all whales are dolphins. It may sound confusing, but all dolphins are simply smaller types of whales.
