they have special bodyparts to let them store heat like human.
Animals don't store heat, metabolism creates heat and fur or feathers (or clothing) just insulates the body to reduce heat loss.
Cold Blooded animals, they can't create body heat so they need to find it somewhere else. If warm blooded animals get to the point that their in a climate they are not suited for, they must conserve their body heat. But technically ALL animals conserve body heat.
snakes and crocodiles can control there body heat by going in the sun snakes and crocodiles can control there body heat by going in the sun
animals
Muscle movement produces the most body heat.
Endotherms or homeotherms are animals that can produce their own body heat through internal processes such as metabolism. They are able to regulate their body temperature independently of the external environment.
yes some animals do as far as i know. they use the fat in their bodies to produce body heat. e.g. horses use their own body heat to keep themselves warm.
They have adaptions to live there. Some have big ears to release alot of heat like the fennic fox. Some can store water easily in their body that lasts for months like the tortoise can store water under it's shell. Alot of animals dig deep burrows to escape the heat. Alot of the animals are nocturnal.
altitude
Animals usually store excess energy in fat cells as fats.
warm animals Mammals
Rats can not regulate their body heat. Most mammals can regulate their body heat when their blood is high enough.
The name that is given to animals that cannot make their own body heat is called a warm blood animal.
