Even-toed ungulates, also known as artiodactyls, are a group of mammals characterized by having an even number of toes on each foot, typically two or four. This group includes animals such as cows, sheep, goats, deer, and pigs. They are primarily herbivorous and have specialized digestive systems to break down plant material. These animals are found in various habitats around the world, from grasslands to forests. Even-toed ungulates play important roles in their ecosystems, such as grazing, which helps maintain plant diversity, and serving as prey for larger predators like wolves and lions.
