Bull Sharks and Their Behavior

The video discusses three shark species known to attack humans: the great white, tiger, and bull sharks. It focuses on bull sharks, highlighting their physical characteristics, aggressive nature, and unique ability to thrive in both marine and freshwater environments. Research using Critter cams and satellite tags reveals their feeding habits and potential role as a keystone species in coastal ecosystems. Despite their presence in shallow waters frequented by humans, the likelihood of a shark attack is low compared to other risks.
