The fennec fox's large ears help keep it cool: when the blood vessels dilate, blood from the body cycles in and dissipates over the expanded surface area. [1]A xerocole (from Greek xēros / ˈ z ɪ r oʊ s / 'dry' and Latin col(ere) 'to inhabit'), [2] [3] [4] is a general term referring to any animal that is adapted to live in a desert.
Many other hot desert animals are nocturnal, seeking out shade during the day or dwelling underground in burrows. At depths of more than 50 cm (20 in), these remain at between 30 and 32 °C (86 and 90 °F) regardless of the external temperature. [92]
Arizona Desert hairy scorpions are a warm-desert species, specially adapted to hot and dry conditions. They are usually found in and around washes or low-elevation valleys where they dig elaborate burrows (up to 2.5 m or 8 ft 2 in) and emerge at night to forage for prey and mates.
Semiarid deserts experience similar conditions to hot deserts, however, the maximum and minimum temperatures tend to be less extreme, and generally range from 10 to 38 °C. Coastal deserts are cooler than hot and semiarid deserts, with average summer temperatures ranging between 13 and 24 °C. They also feature higher total rainfall values.
They are hopping desert rodents found throughout North Africa and Asia. [1] They tend to live in hot deserts. [1] When chased, jerboas can run at up to 24 km/h (15 mph). [1] Some species are preyed on by little owls (Athene noctua) in central Asia. Most species of jerboas have excellent hearing that they use to avoid becoming the prey of ...
The skies are teeming, too: a southern desert shrike, a bird that impales its prey upon spiky branches, oil-black desert ravens and even a critically endangered Egyptian vulture. But most common ...
The Sonoran Desert (Spanish: Desierto de Sonora) is a hot desert and ecoregion in North America that covers the northwestern Mexican states of Sonora, Baja California, and Baja California Sur, as well as part of the Southwestern United States (in Arizona and California). It is the hottest desert in both Mexico and the United States. [3]
The hot temperature of the desert restricts the jerboas to search for food at nightfall, when the temperature is cooler. Diet varies by species, some feeding almost exclusively on vegetation and others are insectivores. They search for sprouting vegetation, roots, and/or dry grains.
