Lagomorpha

Lagomorphs are a special group of animals called the order Lagomorpha. They include animals like rabbits, hares, and pikas. The name "lagomorph" comes from ancient Greek words for "hare" and "form." This shows how these animals look and move.

There are two main families of lagomorphs. The first family is Leporidae, which includes rabbits and hares. The second family is Ochotonidae, made up of pikas. Together, there are about 110 different species of lagomorphs alive today.

Most of these species are rabbits and hares, with pikas making up the rest. Lagomorphs are interesting because of how they look, behave, and live in many parts of the world.

Etymology

The word "lagomorph" comes from two old Greek words: lagos, meaning "hare", and morphē, meaning "form". It describes animals that look like hares. This name was first used in the 1800s by a German scientist named Johann Friedrich von Brandt.

Lagomorphs include rabbits, hares, and pikas. These animals are sometimes grouped with rodents, but they have special features that make them unique.

Taxonomy and evolutionary history

Lagomorphs are rabbits, hares, and pikas. They were first described as a special group in 1811. They are different from rodents because they have four upper incisors. Many names were used for this group before it was called Lagomorpha in 1855.

Scientists are still learning about their early history. They once thought a creature called Eurymylus from eastern Asia was their ancestor. But newer studies suggest they may have come from mimotonids. Mimotonids were small mammals from Asia with teeth like early European rabbits. Rabbits appeared in the late Eocene and spread quickly. Pikas appeared later in the Oligocene in eastern Asia.

Characteristics

Lagomorphs are animals that look a bit like mammals. They have hair, four limbs, and make milk to feed their babies. But they also have special traits. For example, they have four upper front teeth, not two, which makes them different from most other animals.

Rabbits, hares, and pikas are the three main kinds of lagomorphs. Rabbits and hares have strong hind legs that help them hop. Pikas are smaller and live in mountains. They store dried plants for food in winter. Hares are usually bigger than rabbits and live alone, while rabbits often live together in groups underground. Both rabbits and hares are important because many animals eat them.

Distribution

Lagomorphs, such as rabbits, hares, and pikas, live on every continent except Antarctica. They are not found in the West Indies, Madagascar, or many islands. They are not native to Australia, but humans brought them there, and now they live in many parts of the country. European hares can be found in much of the southern cone of South America.

Biology

Lagomorphs include rabbits, hares, and pikas. They have special ways to get nutrients from their food. They eat something called cecotropes, which help them get more nutrients from hard-to-digest fiber.

Many lagomorphs have babies several times a year. Rabbit and pika babies, called kits, are born after a short time and grow quickly. Hare babies are called leverets and are born after a longer time. Some lagomorphs live in groups, while others, like hares, often stay alone but may travel in small groups. Rabbits and pikas use their burrows to stay safe, while hares use their speed to escape from danger.

Classification

See also: List of lagomorphs

Lagomorphs are animals that include rabbits, hares, and pikas. They belong to the order Lagomorpha. There are two main families: Leporidae, which includes rabbits and hares, and Ochotonidae, which includes pikas.

Today, there are about 110 species of lagomorphs. Most of them are in the Leporidae family, with many different types of rabbits and a few kinds of hares. The pikas are the smallest group.
