The scientific term for an animal that only eats meat is "carnivore." Carnivores primarily consume the flesh of other animals for energy and nutrients. This dietary category includes a wide range of species, from large predators like lions and wolves to smaller ones like frogs and certain bird species. Carnivores have physiological adaptations, such as sharp teeth and claws, that help them hunt and consume their prey effectively. They play a crucial role in maintaining ecological balance by controlling populations of other species and contributing to the overall health of their ecosystems.
