Bull sharks scare me. Sharks are supposed to be in the ocean, but some sharks can live for extended periods in fresh water, too. Bull sharks have been found as far inland as the Great Lakes.
Nevertheless, I seem to be in the minority. A recent survey found that most people like sharks and don’t let a publicized shark attack deter them from their work or recreation in the water.
Bull sharks are mostly found in warm, coastal waters. Although they stay in fresh water for a time, they are not freshwater sharks.
In this video, researchers say the bull sharks are living in rivers probably because of the lack of competition. They can bear young in fresh water without other sharks eating the babies.
