Lagomorpha

Lagomorpha is an order of mammals that includes rabbits, hares, and pikas. This group is also known as the lagomorphs. The name of the order is derived from the Ancient Greek λαγώς (lagōs, "hare") + μορφή (morphē, "form").

Characteristics

Lagomorphs are small to medium-sized mammals. The majority of species have short tails and long ears. They have a body plan that allows for quick, agile movements. They are herbivorous, feeding on a diet of grass, leaves, buds, tree bark, and roots.

Taxonomy

The order Lagomorpha is divided into two families: the Leporidae (hares and rabbits) and the Ochotonidae (pikas). The Leporidae family is further divided into two genera: Lepus (hares) and Oryctolagus (rabbits). The Ochotonidae family is divided into one genus: Ochotona (pikas).

Evolution

The earliest lagomorphs were found in Asia and date from the early Eocene. The divergence of the two families is believed to have occurred in the late Eocene or early Oligocene.

Distribution and habitat

Lagomorphs are found in a variety of habitats, including deserts, tundra, and forests. They are found in every continent except Antarctica.

Behavior

Lagomorphs are known for their high reproductive rate. They are also known for their ability to consume large amounts of plant material, which is facilitated by their specialized digestive system.

Conservation

Many species of lagomorphs are considered threatened due to habitat loss, disease, and overhunting.
