Desert hedgehog
The desert hedgehog is a remarkable species adapted to survive in arid environments, typically in regions receiving less than one inch of rainfall annually. These small mammals, measuring between 5.5 to 11 inches in length and weighing 10 to 18 ounces, are characterized by their distinctive gray and white coloration with sharp spines that serve as a defense mechanism against predators. They thrive in extreme temperatures, often ranging from 104 to 108 degrees Fahrenheit, and enter hibernation when temperatures drop below 68 degrees Fahrenheit.
Dietarily, desert hedgehogs are unique as they can consume scorpions and snakes without harm, relying on insects and carrion as primary food sources. With a solitary and nocturnal lifestyle, they are equipped with long claws for burrowing into sandy soil and evading threats. Reproduction occurs once a year after hibernation, resulting in a litter of 2 to 6 offspring. Remarkably, the young are born with spines that become visible shortly after birth. In the wild, these hedgehogs typically live around 3 to 4 years, while in captivity, they can reach up to 10 years. Their unique adaptations make them a fascinating subject of study in the context of desert ecology.

Desert hedgehog
Desert hedgehogs are unique because they can live in the desert where rainfall is less than one inch (less than 2 1/2 centimeters) a year. They eat scorpions without being stung and snakes without being poisoned. They have sharp spines to protect themselves.
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Eulipotyphla
Family: Erinaceidae
Genus: Paraechinus
Species: Aethiopicus
Desert hedgehogs are 5 1/2 to 11 inches (140 to 280 millimeters) long and have tails 1/2 to 1 1/2 inches (one to four centimeters) long. They weigh 10 to 18 ounces (280 to 510 grams). These creatures are usually gray and white on top, brown and white underneath, white around the face, and have brown noses. They live in desert and semi-desert areas where the temperature is often 104 to 108 degrees Fahrenheit (40 to 42 degrees Celsius). When the temperature drops below 68 degrees (20 degrees Celsius), the hedgehog hibernates.
In this hot and dry habitat, the desert hedgehog eats insects, scorpions, snakes, and other dead animals (carrion). They find food on the ground as they walk or burrow into the soil.
Although they are the smallest hedgehogs, they are protected by 3,000 to 5,000 sharp spines about one inch long covering their bodies. When attacked, a hedgehog can curl up into a prickly ball. They may attempt to outrun their attacker first at speeds of up to 12 miles (19 kilometers) per hour. They also have long, sharp claws for fighting an attacker. Desert hedgehogs may burrow 1 1/2 to 2 feet (1/2 to 1 meter) deep in the sandy soil, using their sharp claws.
Hedgehogs are solitary (they live alone) and nocturnal (active at night). They mate once a year after hibernation. A female gives birth after a gestation period of 30 to 40 days to 2 to 6 young. Each baby hedgehog has its spines at birth just under their skin. The spines are visible a couple of hours after birth and fully grown after 40 days.
Desert hedgehogs live 3 to 4 years in the wild and up to 10 years in captivity.
