Reef sharks are a group of shark species commonly found in tropical and subtropical waters, particularly around coral reefs. They are known for their slender bodies and pointed snouts, which help them navigate through the complex reef environment. Some common types of reef sharks include the Blacktip Reef Shark, Whitetip Reef Shark, and Grey Reef Shark. These sharks play a crucial role in maintaining the health of coral reef ecosystems by controlling the populations of smaller fish. Typically, reef sharks are not aggressive towards humans, but they can be curious and may approach divers. They primarily feed on small fish and invertebrates, using their keen sense of smell to locate prey. Reef sharks are often seen swimming in groups, known as schools, and they are important indicators of the overall health of their marine habitats. Conservation efforts are essential to protect these species from overfishing and habitat loss.
