Why do reptiles live in the desert?
REPTILES IN THE DESERT Reptiles thrive better in warm deserts than in cold deserts, because the low temperatures would not allow them to develop their life activity. Map by Vzb83 of the warm deserts, both arid and semiarid, of the world. Warm deserts not always have extremely high temperatures.
What adaptations of reptiles are important for living on dry land?
One of the key adaptations that permitted reptiles to live on land was the development of their scaly skin which contains the protein keratin and waxy lipids, reducing water loss from the skin. Due to this occlusive skin, reptiles cannot use their skin for respiration, as do amphibians; all breathe with lungs.
How can lizards survive in dry areas?
A number of lizard species have adapted to life in the desert. Some desert lizards have toes fringed with spiny scales to help them run across the sand without sinking. Others burrow into the sand to escape the desert’s intense heat, to hide from predators, or to search for small animals that they prey upon.

How does a reptile survive in a dry environment?
Reptiles living in dry habitats are relatively waterproof, and most reptiles have water requirements that are only about 1–5% of those of amphibians. The reptiles have nearly impermeable skin, they produce relatively dry feces and may have nasal salt glands that eliminate dietary salts with little water loss.
Where do reptiles live most of the time?
Because of this, they have to live in warm and sunny climates. Reptiles prefer to live in warm, dry climates rather than wet ones. They are most numerous in areas such as deserts and semi-deserts.
How does evaporation occur in lizards and snakes?
Reptiles living in moist habitats have much higher rates of evaporation, up to 30% of body mass per day in tropical lizards, and 200% per day in dry air in a tropical burrowing snake. In typical reptiles, about half of the total evaporation occurs through the skin, whereas the other half occurs through the respiratory tract.
Is the skin of a reptilian reptile evaporative?
Reptilian skin has a very high resistance to evaporative water loss (Lillywhite and Maderson, 1988 ). Thus, those avenues of water flux that were inconsequential in amphibians, such as metabolic water production and fecal water loss, are major aspects of reptilian water budgets.
How are reptiles adapted to live on land?
One of the key adaptations that permitted reptiles to live on land was the development of their scaly skin which contains the protein keratin and waxy lipids, reducing water loss from the skin. Due to this occlusive skin, reptiles cannot use their skin for respiration, as do amphibians; all breathe with lungs.
Why are there no reptiles in tropical climates?
The absence of reptiles in these regions is due to the frigid temperatures. Reptiles can’t produce their own body heat and rely on the temperature around them to maintain body heat, this is known as thermoregulation. Tropical and warm temperate climates are home to the most diverse range of reptiles.
Why do reptiles not use their skin for respiration?
Due to this occlusive skin, reptiles cannot use their skin for respiration, as do amphibians; all breathe with lungs. Reptiles are ectotherms: animals whose main source of body heat comes from the environment. This is in contrast to endotherms, which use heat produced by metabolism to regulate body temperature.
How does a reptile keep its body temperature warm?
The temperature is too cold for them to function properly, so they retreat to a warm area to keep their body temperature up until the temperatures rise again. ‘Thermoregulation’ and ‘Cold Blooded’ are often terms people associate with the need for a reptile to gain heat from their environment.
