Odd-toed ungulates are a group of mammals characterized by having an odd number of toes on their feet, typically one or three. This group includes animals like horses, zebras, and rhinoceroses. They belong to the order Perissodactyla, which distinguishes them from even-toed ungulates, such as cows and sheep. These animals are primarily herbivorous and have specialized digestive systems to process plant material. Odd-toed ungulates play important roles in their ecosystems, often influencing vegetation patterns and serving as prey for larger predators. Their unique adaptations help them thrive in various habitats around the world.
