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.
Animals other than humans regulate and maintain their body temperature with physiological adjustments and behavior. Desert lizards are ectotherms, and therefore are unable to regulate their internal temperature themselves. To regulate their internal temperature, many lizards relocate themselves to a more environmentally favorable location.
The green line represents the base temperature of the burrow. Lizards are ectotherms and use behavioral adaptations to control their temperature. They regulate their behavior based on the temperature outside; if it is warm they will go outside up to a point and return to their burrow as necessary.
A female desert spiny lizard will lay anywhere from 4 to 24 eggs during the summertime. [4] A fully grown desert spiny lizard will reach a body length of up to 5.6 inches. Besides their bright colors, the desert spiny lizard changes to darker colors during the winter to allow them to absorb more heat from the sunshine, and become lighter during ...
These lizards are well adapted to desert conditions; they are active at temperatures up to 39 °C (102 °F). Chuckwallas hibernate during cooler months and emerge in February. [5] Juveniles emerge first, then adults, as temperatures reach around 32 °C (90 °F). [5] Mating occurs from April to July, with five to 16 eggs laid between June and ...
Homeothermy, homothermy or homoiothermy [1] is thermoregulation that maintains a stable internal body temperature regardless of external influence. This internal body temperature is often, though not necessarily, higher than the immediate environment [ 2 ] (from Greek ὅμοιος homoios "similar" and θέρμη thermē "heat").
The central netted dragon or central netted ground dragon (Ctenophorus nuchalis) is a species of agamid lizard occurring in a wide range of arid to semiarid regions of Australia. It is widespread across the continent, commonly found in open, sandy, desert habitats. It is a popular pet and can often be found in zoos.
The body temperature of the lizard during hibernation is 15.0 to 30.5 °C, but in many areas, the average body temperature during hibernation is around 16-18 °C. [5] The species is one of the few monitor lizards that tolerate relatively cold temperatures, being present as far north as south-west Kazakhstan. [12]
