Visayan warty pig : ウィキペディア英語版 | Visayan warty pig
The Visayan warty pig (''Sus cebifrons'') is a critically endangered species in the pig genus (''Sus''). The Visayan warty pig is endemic to two of the Visayan Islands in the central Philippines, and is threatened by habitat loss, food shortages, and hunting – these are the leading causes of the Visayan warty pig's status as critically endangered. Due to the small numbers of remaining Visayan warty pigs in the wild, little is known of their behaviors or characteristics outside of captivity. == 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.
