Herbivorous fish are species that primarily feed on plant material, such as algae, seaweed, and aquatic plants. These fish play a crucial role in their ecosystems by helping to control algae growth and maintain the health of coral reefs. Common examples of herbivorous fish include parrotfish and surgeonfish. These fish have specialized teeth and digestive systems that allow them to efficiently process plant matter. Many herbivorous fish are found in tropical and subtropical waters, where they contribute to the biodiversity of marine environments. Their feeding habits support not only their own health but also the overall balance of their habitats.
