Most desert animals are nocturnal because it allows them to avoid extreme heat during the day. Some predators are nocturnal because their prey is active at night.Continue Reading
Small burrowing mammals, such as mice, stay underground during the hottest part of the day. This allows them to avoid burning their feet on the hot sand or rock and to avoid the harsh sunlight. When they leave their burrows at dusk, they attract predators, such as snakes. Most desert reptiles, such as rattlesnakes, are crepuscular, which means they are active at dawn and dusk. This allows them to hunt the rodents that become active at night. Some of these reptiles do not always avoid the sun because they need the heat to help regulate their body temperatures. However, during the day, they are generally sluggish and prefer to bask on rocks rather than hunt or travel.
The majority of desert birds are nocturnal. Owls come out at night to hunt nocturnal rodents and reptiles. Some birds are active throughout the day but hunt mostly at night and try to avoid the sun during the day. Amphibians, such as toads, burrow into the sand during the day, going deep enough to find coolness. They hunt insects that come out after dark.Learn more about Zoology
According to the Smithsonian National Zoological Park, warm-blooded animals regulate their body heat internally, while the body temperature of cold-blooded animals depends on the temperature of their surroundings. Mammals are warm-blooded, while reptiles, insects and arachnids are not. Amphibians and fish also require external heat sources in order to live.Full Answer >
"Warm-blooded" is used to describe animals that generate their own heat. Warm-blooded creatures are often called ectotherms. Mammals and birds are warm-blooded; reptiles and amphibians are cold-blooded.Full Answer >
Nocturnal animals are active during the night, and diurnal animals are active during the day. In addition, both sorts of animals are adapted to the differing light levels and challenges of the different parts of the day that they are awake.Full Answer >
Lizards survive in the desert because they have many adaptations as reptiles that help them to avoid the extreme heat during the day, the extreme cold during the night and keep moist despite the dry weather. The first of all of these adaptations was the adaptation that took the lizard from a swimming lung fish in the Paleozoic era to an earth-crawling lizard today.Full Answer >
