The video discusses three shark species that attack humans, focusing on the bull shark. Bull sharks are known for their aggressive nature and unique ability to thrive in both marine and freshwater environments. They are often found in shallow coastal waters, posing a potential threat to humans. Research using Crittercams reveals insights into their behavior and habitat, showing that they tend to stay in specific regions. Despite their presence in human-frequented areas, the likelihood of a shark attack is low compared to other risks.
