They are blind, subterranean small mammals [5] with small ears, tails and eyes that are all covered by skin and fur. They have unique cranial and nasal morphology. [ 5 ] On their nose is a large leathery pad to help them burrow.
The female desert hedgehog gives birth to up to six young, in a burrow or concealed nest, after a gestation period of around 30 to 40 days. The young are born deaf and blind, and with the quills located just under the skin, to prevent damage to the female during birth. The quills emerge within a few hours, and the eyes open after around 21 days.
The three main vulnerabilities against the sand are through the eyes, ears, and nose. [37] To keep sand out of their eyes, xerocoles including reptiles and birds, and some amphibians and mammals [38] have a nictitating membrane in their eyes: a third, transparent eyelid that protects the cornea from blowing sand and can dislodge it from the eye.
This primitive genus, Eocaecilia, had small limbs and well-developed eyes. [46] In their 2008 description of the Early Permian amphibian Gerobatrachus , [ 47 ] Anderson and co-authors suggested that caecilians arose from the Lepospondyl group of ancestral tetrapods , and may be more closely related to amniotes than to frogs and salamanders ...
Pikas are small mammals, with short limbs and rounded ears. They are about 15 to 23 cm (5.9 to 9.1 in) in body length and weigh between 120 and 350 g (4.2 and 12.3 oz), depending on species.

Golden moles are small insectivorous burrowing mammals endemic to Sub-Saharan Africa. They comprise the family Chrysochloridae (the only family in the suborder Chrysochloridea ) and as such they are taxonomically distinct from the true moles , family Talpidae , and other mole -like families, all of which, to various degrees, they resemble as a ...
Desert monitors lay 10-20 eggs in a clutch. Females, after laying, will linger around the area. [13] Reproduction normally takes place between May and July. Copulation occurs in May and June, and the lizards normally lay their eggs from the latter part of June through the beginning of July. [11]
Most dasyurids are roughly the size of mice, but a few species are much larger. The smallest species is the Pilbara ningaui, which is from 4.6 to 5.7 cm (1.8 to 2.2 in) in length, and weighs just 2 to 9 g (0.07 to 0.3 oz), while the largest, the Tasmanian devil, is 57 to 65 cm (22 to 26 in) long, and weighs from 6 to 8 kg (13 to 18 lb).
