Will a Dolphin Scare Away a Shark?

Do sharks stay near dolphins?

Not really. It's also a common belief that if there are dolphins in the area, sharks are unlikely to be nearby. This is dependent on the environment and species of shark or dolphin. Sharks and dolphins share the same food source, so they're likely to be in the same area at the same time in hopes of catching a meal.

What scares a shark away?
