4. They’re slow swimmers and migrate a long way

With the exception of the Mediterranean Sea, whale sharks can be found in all temperate and tropical oceans around the world and migrate thousands of miles to different feeding grounds. But moving is slow going, as they move at speeds of little more than 3 miles per hour.

5. Along with other sharks, they’re under threat

Many sharks are accidentally caught in fishing gear, as well as caught deliberately for their fins, which are a delicacy in Asia. Their ocean home is also in danger. From climate change warming the water – affecting both habitats, prey, and shark population shifts – to plastic pollution, which could cause entanglement or be ingested, especially by filter feeders.
