Cows have evolved a variety of adaptations that help them survive, including the ability to sweat, regulate body temperature and digest foliage that would be undigestible for many mammals. The modern cow's digestive system is sometimes said to be its most unique and important adaptation.Continue Reading
Cows spend much of their time chewing and digesting food. The entire digestive process can take 70-100 hours. This long process is the result of a set of adaptations that makes it possible for cows to eat a variety of foraged plants and leaves.
Cows have four-chambered stomachs that allow them to complete a repeated process of chewing and partially digesting tough and fibrous foliage. Cows also have adapted impressive processes to manage and regulate body temperature, from things like sweating and panting to adjusting behavior by seeking shady, cooler areas in hot weather. These adaptations have helped make cows hardy animals.Learn more about Barnyard Mammals
Bison are adapted for migratory grazing by having low-slung heads, muscular limbs and necks, digestive systems that are able to extract nutrients from fibrous vegetation, hard hooves for rapid travel and woolly coats for insulating against cold prairie nights. They also tend to eat during the coolest parts of the day, early morning and evening, to avoid overheating under the prairie sun.Full Answer >
Llamas live in high altitude places, such as the Andean Mountains, and have adapted a high hemoglobin content in their bloodstream. Instead of circular, their red blood cells are oval shaped, which helps them to survive in environments where there is little oxygen.Full Answer >
