Pedetes

life science Maturity 11-13 Next article →

The genus *Pedetes* contains a group of rodents known as springhares. These animals belong to the biological family Pedetidae. They are primarily found across southern and eastern Africa. Springhares are unique because they use a specific way of moving to navigate their environment. Scientists study them to understand how rodents adapt to different habitats. This genus is important for understanding the history of life in Africa.

Springhares have a very specific lifestyle and way of moving. Most of these rodents are nocturnal, which means they are active at night. During the daylight hours, they sleep inside burrows that they dig themselves. When night falls, they emerge to find food. They eat various types of vegetable matter, such as foliage and roots. They also occasionally eat arthropods, which are small animals like insects. To move around outside their burrows, they usually hop on their hind legs.

There are several different types of springhares within this genus. Some species are extant, meaning they are still living today. Others are extinct and only exist as fossils from the past. One known fossil species is *Pedetes laetoliensis*. This prehistoric rodent lived during the Pliocene epoch. Researchers discovered these fossils at a site in Laetoli, located in northern Tanzania.

The classification of these animals has changed over time. For much of the 20th century, scientists grouped many species together. They placed the living and prehistoric species into one single group called *P. capensis*. This made the genus monotypic, which means it contained only one recognized species. However, modern science recognizes multiple species within the genus *Pedetes*. These include the South African springhare, or *Pedetes capensis*, and the East African springhare, or *Pedetes surdaster*.

Springhares also have interesting ways of communicating and physical traits. They use a variety of vocalizations to interact with one another. These sounds include grunts and bleats. They also use a specific piping contact call to stay in touch. Another surprising fact involves their fur. The coat of a springhare exhibits fluorescence. This means their fur will glow a fluorescent color when viewed under a black light.

In the past, the population of springhares faced significant challenges. In 1996, the IUCN listed the species as vulnerable. This was because the population had decreased by approximately 20 percent over ten years. This decline was caused by intense hunting and the loss of their natural habitat. Fortunately, this negative trend did not continue. Today, the species are listed as being of Least Concern. This means they are not currently considered to be at high risk.

Springhares are often compared to other animals that look or move like them. For example, the hopping mouse in Australia and the jerboa in Africa and Asia move in similar ways. There are also jumping mice in China and North America that share these traits. Some of these similarities are examples of parallel evolution. This happens when related species develop similar traits. Other animals, like the Kultarr, show convergence. Convergence is when unrelated animals develop similar body plans or colors.
