International Day for Biological Diversity

On this day when we honor all the world"s species and their interdependence, the Burchell"s zebra and the cattle egret give us a great example of commensalism, a type of symbiosis in which one species gets a benefit without helping or hurting the other species: As the zebra grazes in the grass, it stirs up insects for the egret to eat.
