Carnivorous fish are species that primarily eat other animals, including smaller fish, crustaceans, and even insects. They have adaptations such as sharp teeth and strong jaws to help them catch and consume their prey. Examples of carnivorous fish include sharks, pike, and barracuda. These fish play a crucial role in aquatic ecosystems by helping to control the populations of other species. Their predatory behavior contributes to the balance of marine and freshwater environments, ensuring that no single species dominates the ecosystem. Understanding carnivorous fish is important for conservation and management efforts in aquatic habitats.
