The warthog (Phacochoerus africanus) is well distributed throughout Sub-Saharan and Central Africa and is apparently the only pig which has adapted for grazing in savanna habitats. During the dry season the warthog relies more on underground rhizomes, bulbs and tubers. This pig is also unique in that it grazes while resting on the callouses of its carpel joints (wrists). They collect as small matriarchal social groupings. While bachelor males tend to gather together, the older males are usually solitary.

Refractive Index is a term used to describe the effect of a lens causing light to bend, based on the velocity of light in a vacuum to its velocity in a specific medium (such as glass). This determines the amount of light reflected and the angle of the internal reflection.
