However, recently a relationship to chevrotains in the infraorder Tragulina has been proposed. Unusually for most mammals, female water chevrotains are larger than males. Moschiola, the spotted chevrotains, are a genus of small even-toed ungulates in the family Tragulidae. Chevrotains are the smallest hoofed mammals in the world. Instead, the chevrotains are probably the closest living relatives to these ancient deer-like animals.
