![South Africa - Two Adult Warthogs with Their Child](https://marybethclark.com/wp-content/uploads/2017/05/South-Africa-Two-Adult-Warthogs-with-child.png)
Sturdy and bristly, warthogs have a wide habitat tolerance living in moist and arid savannahs. They are the only pigs who can live for months without water. Their tusks are unusual: the upper set emerge from the snout forming a semi-circle, and the lower set have a sharp cutting edge for efficient foraging. Their tusks can grow up to 1 foot (30 cm) long, unfortunately making them susceptible to poaching.
