Certain subspecies of caribou — the more scientific name of North American reindeer — in Canada trek over 3.000 miles annually from north to south. These hardy animals have some of the longest ...
The bacteria and protozoans in the stomach of a reindeer break down lichen compounds into sugars that the animals use for sustenance. Reindeer need a lot of food to survive a long winter.
Reindeer also travel, feed, and rest together in the wild, sometimes forming super-herds of up to 500,000 animals. Tundra reindeer migrate between forest and tundra in these massive groups in an ...
The mountain reindeer has several physiological adaptations to cope with different environmental temperatures. Reindeer have hemoglobin that allows for high oxygen unloading even at very cold temperatures. [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.

Reindeer herders on the Seward Peninsula have experienced significant losses to their herds from animals (such as wolves) following the wild caribou during their migrations. [citation needed] Reindeer meat is popular in the Scandinavian countries. Reindeer meatballs are sold canned. Sautéed reindeer is the best-known dish in Sápmi.
While deer species aren’t known for their seasonal migrations, they are famous for their big appetites. Deer love food and will go to great lengths to eat their preferred meals. Reindeer, in ...
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.
