Lagomorpha
Lagomorpha is an order of mammals characterized by their unique dental structure, which includes two pairs of upper incisors and no canines. This group consists of rabbits, hares, and pikas, all herbivorous animals that have adapted to various habitats around the world. Rabbits are small mammals with long ears and strong hind limbs, often associated with burrowing behavior. Hares are similar but generally larger, with longer ears and a more robust build. Pikas are smaller relatives without external ears, living in high-altitude mountain ranges. Lagomorphs share certain traits with rodents, such as their gnawing habits, but they possess distinct anatomical differences, including a wider cecum for fermentation of plant material and a more complex skull structure. Historically, lagomorphs were classified as a subgroup of rodents, but modern taxonomy recognizes them as a separate order within the infraclass Eutheria.
