Shark and Lifeguard are roles associated with water environments, but while a shark is a marine animal (or a fictional character), a lifeguard is a trained professional responsible for water safety. The key difference lies in their nature and purpose: sharks are predators in the ocean, whereas lifeguards are safety personnel in pools and beaches.
