Mixed herds of zebra and wildebeest fording a waterway durng the Great Migration, Lake Ndutu, Serengeti, Tanzania.
These two species are often found together. Several explanations for this exist including; Wildebeest graze predominantly on short grass. Zebra, on the other hand, have long front teeth designed to shear long grass. In this way, zebra act as lawnmowers preparing the ground for the wildebeest. Also, zebra have better memories and are able to recall last year's migration routes, remembering hazardous places and areas of safety. On the other hand, wildebeest are natural water diviners. They need to drink at least every other day and have evolved a well-developed sense of smell that allows them to detect water even when the savannah seems dry so they can lead the zebra to water.
