The family Octodontidae consists of small rodents commonly known as octodonts, which are native to South America. They are characterized by their unique dental structure, featuring eight incisors that help them efficiently gnaw on plant material. Octodonts are primarily found in diverse habitats, including forests, grasslands, and deserts. These rodents are typically nocturnal and social, often living in groups. They have a varied diet that includes seeds, fruits, and leaves. Some well-known members of the Octodontidae family include the degu and the octodon, both of which are popular in the pet trade due to their friendly nature.
