Warthogs are very vocal wild pigs that live in family groups called sounders. They communicate with each other through grunts, squeals, growls and squeaks. Males are easily recognized with two pairs of tusks protruding from their snouts. These tusks are rarely used, however, as warthogs are not territorial and only fight over females for a very short time during breeding season.
Come meet Walter the warthog in the nursery. Soon he will be taking his trainers for walks through Africa.
