The blou wildebeest is found on short grasslands of both southern and eastern Africa. They are known for their large pair of curved horns which grow close together at the base, but then curve outward, inward and slightly backward. This antelopes' common name "blue wildebeest" refers to its silvery-blue coat. However, it is also known as a "gnu", an alternative name given to the buck by the Khokhoi people.
