Polar-bears and walruses are two examples of animals that have adapted to extreme cold temperatures. There are others - arctic fox, various species of penguins, etc.
Camels are an example of adaptation to extreme (desert) heat - though in Siberia, they also have to adapt to cold.
Animals or plants that have adapted to temperate climates have certain behavior patterns. Plants and animals in a desert for instance have adapted to use of low volumes of water and extreme heat.
animals that live there like the camel are adapted to the lack of water and extreme heat other animals found there are snakes
Evolution. Over hundreds of years animals will change to adapt to there surroundings.
The average temperature for wild animals varies depending on the species and their habitat. Many mammals have body temperatures close to 37°C (98.6°F), similar to humans. However, animals in extreme environments may have adapted to tolerate much higher or lower temperatures.
People and animals in tropical climates have adapted by having smaller body sizes to dissipate heat more effectively, possessing sweat glands for cooling, and developing behaviors such as seeking shade during the hottest parts of the day. Animals have also adapted by having specialized mechanisms, such as fur or feathers that help regulate body temperature, and by changing their activity patterns to avoid extreme heat.
Most animals migrate to warmer climates once the cold weather begins. Some animals have adapted to life in the taiga by hibernating when temperatures drop. Other animals have adapted to the extreme cold temperatures by producing a layer of insulating feathers or fur to protect them from the cold.
Desert animals have adapted to the desert climate with their tough, scaly skin that prevents water loss and protects them from extreme heat in the day & freezing temperatures at night.
The cells that are in thermophiles need extreme heat to multiply, they have adapted by changing their body temperature and now survive best in hot climates.
A desert ecosystem typically features sparse vegetation, sandy or rocky terrain, and extreme temperature fluctuations. Plants and animals in deserts are adapted to survive with minimal water availability and high temperatures. Common desert animals include reptiles, insects, and rodents that are active during cooler periods of the day.
Wildlife is scarce in the innuitions, but the ones that have adapted to the extreme cold temperattures are moutain goats, arctic owls, arctic foxes and arctic hares.
The Southern Ocean is liquid under its frozen top, and these animals are adapted to the extreme cold, some with versions of anti-freeze in their systems.
Cacti and other succulents are adapted to a hot, dry climate.
