How Does a Shark Chase and Catch a Fish?
What looks like a simple chase is actually a highly developed biological hunting system.
Sharks use several specialized senses to locate and track prey. Their lateral line system detects tiny vibrations and water movements created by swimming fish. This can help a shark determine the direction and movement of nearby prey—even when visibility is poor.
Sharks also possess electroreception through sensory organs called the ampullae of Lorenzini. These organs can detect extremely weak electrical signals produced by the muscles and nervous systems of living animals.
Once the shark gets close, vision, smell, vibration detection and electroreception work together to help it locate and capture its prey.
Many shark species naturally feed on fish. For example, NOAA reports that juvenile white sharks commonly eat bottom fish, schooling fish and squid, while sharks in general are important predators in marine ecosystems.
Nature doesn't need artificial technology—evolution has already built incredible biological systems.
