Visayan Warty Pig - Subspecies

Subspecies

• Cebu warty pig (Sus cebifrons cebifrons) (believed to be extinct)

• Negros warty pig (Sus cebifrons negrinus). There are two separate remaining populations of S. c. negrinus – on the islands of Negros and Panay, respectively. Both populations have been physically and genetically isolated since the last ice age (c. 12,000 yrs). The current conservation program for S. c. negrinus includes successful breeding programs at the Rotterdam Zoo for pigs of Negros origin, and at the San Diego Zoo for pigs of Panay origin.

Although it is believed that S. cebifrons can now only be found in Negros and Panay, some studies report of the possibility that a small population exists on the island of Masbate.
