[1] This is essential because reindeer limbs are often kept much colder than core body temperature, a phenomenon known as regional ...
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature. [2]
Cold-blooded animals are often limited by external temperatures, which can affect their ability to hunt, escape predators, and carry out other essential activities. Homeothermy could have provided a selective advantage by allowing animals to be active for longer periods of time, increasing their chances of survival.
Reindeer live in the far northern regions of Europe, North America, and Asia.They enjoy colder climates like tundra and boreal forests. We can find them in northern countries, which include:
In addition to meat production, reindeer are also an extremely valuable resource for both summer and winter tourism, as they are one of the main attractions for foreign tourists.
