What specialized dietary behavior, involving the consumption of soil or clay, is observed in Western Gorillas, and what is the proposed reason for this practice?
Geophagy, believed to provide essential minerals and salts or neutralize plant toxins
Western Gorillas engage in a behavior known as geophagy, which involves the intentional consumption of soil or clay. This practice is particularly noted among herbivores whose primary diet consists of fibrous vegetation like leaves and stems, which can sometimes be deficient in crucial nutrients. The prevailing scientific belief is that ingesting soil helps supplement the diet with essential minerals and salts that are lacking in the vegetation. Furthermore, the clay components may play a role in binding to or neutralizing certain toxins present in some of the plants they consume, providing a form of natural detoxification that aids in their digestion of tough, fibrous material.
