Sundevall's jird is a medium-sized gerbilline rodent with an average mass of about 100 g (3.53 oz).[2] They can range in sizes depending on sex. The average length (not including the tail) is about 15 cm (5.91 in).[3] Their tails can be as long as their bodies. Sundevall's jird has a soft, fine, light brown fur, with a lighter underbelly.[3]
Distribution and habitat
The Sundevall's jird is found in dry habitats like deserts across northern Africa.[3] It can be found in rocky areas, but prefers sand-like soil.[3] They create burrows in the sand where they create nests.[4]
Reproduction
Like any mammal, the Sundevall's jird cares for its offspring by producing milk. Being a relatively small mammal, the Sundevall's jird must intake an increased amount of calories in order to produce enough milk.[4] Gestation can last between 18 and 22 days and they give birth to between 2 and 7 pups.[4] Young are born without fur, are blind, and have very long whiskers.[3] The breeding season for Sundevall's jird is from January to September, with peak times from February to May.[4]
Parasites
The Sundevall's jird can be occupied by a variety of parasites, especially species of fleas.[2] It has been found that male Sundevall's jird harbor more species of parasites than females do, which is still being studied.[2] Along with parasites come the parasites of parasites, in this case bacteria. Bacteria can be transmitted to the Sundevall's jird by the flea biting the rodent.[5]
