General Description


These giants stand up to 1.8 meters tall, with males weighing over a ton and females around 400 kilograms. Despite their size, these mammals are fast and can reach speeds of up to 65 kilometers per hour. Their thick brown fur sets them apart, as it grows abundantly around their face and head. Additionally, Bison have short horns, about 60 centimeters long, proportional to their bodies.

Diet and Habitat


These impressive animals thrive on a diet of plains grasses, herbs, shrubs, and twigs. Due to their unique digestive system, they must regurgitate and chew their food as part of the final stage before digestion. Besides, they spend most of their waking hours walking long distances to find food, relying heavily on water. Since bison can’t last long without water, they seek abundant bodies of water to satisfy their thirst.

Life Expectancy


The American bison have pregnancies that last around 9 months - like humans do! Adults take care of them during the first years of their lives until they reach adulthood at 3 years of age. However, their lifespan ranges between 12 and 20 years.

Did You Know?

Despite common confusion, bison and buffalo are different! American bison have a distinctive hump and fur, while Asian water buffalo have a softer coat and longer horns.
