Wildlife photographer Marie-France Grenouillet captured this spectacular photo of a giraffe spitting dust out after eating soil in Ruaha National Park, Tanzania.
The act of eating soil, clay and dirt, called geophagy, is extremely common in mammals, especially in herbivores. Giraffes eat soil in order to take in minerals such as salt, copper, iron and zinc. The clay also acts as a medicine by binding fungal toxins, internal toxins, toxic chemicals, and bacteria.
