How do sharks detect their prey in the water?

Sharks have several highly developed senses that allow them to detect prey in the water. One of their key tools is their acute sense of smell, which enables them to detect blood and other chemicals in the water from miles away. Sharks also have electroreceptors called the ampullae of Lorenzini, which allow them to sense the weak electrical fields generated by the muscles and heartbeats of prey. Their excellent vision and lateral line system, which detects vibrations in the water, further enhance their hunting abilities.
