During the breeding season, the spiky tuft of hair on the head of male Visayan warty pigs grows into a mane that can be as long as 9 inches (23 cm). When they feel threatened, they will raise their mane, which makes them appear larger and more imposing. This behavior is a form of intimidation that is meant to deter potential predators.
Despite being discovered in 1997, relatively little is known about Visayan warty pigs and their behavior in the wild
Wild pigs all have straight tails; only domestic pigs have curly ones.
Pigs do not sweat and therefore need to cool off in mud wallows and water.
Captive Visayan warty pigs are very curious and playful and like to wallow in mud.
For some, the pig represents fortune, happiness, honesty and virility.
Pigs have a strong sense of smell and a disk of cartilage at the tip of their snouts for extra strength and flexibility when rooting.
There are several stories of pigs who have saved human lives, such as Pru who pulled her owner from a muddy bog and Priscilla who saved a little boy from drowning.
Visayan warty pigs appear to play a major role in dispersing the seeds of some species of plants.
