Caviomorphs are a group of rodents primarily found in South America. This diverse group includes species such as capybaras, guinea pigs, and agoutis. They are characterized by their unique dental structure and adaptations to various habitats, ranging from forests to grasslands. These rodents are known for their social behavior and varied diets, which can include grasses, fruits, and seeds. Caviomorphs play important ecological roles, such as seed dispersers, and are significant in the diets of many predators. Their evolutionary history dates back millions of years, making them a fascinating subject of study in mammalogy.
