I took this picture in Chester Zoo during our visit last week. The Visayan warty pig or Sus cebifrons which is a critically endangered species of pig.
This pig may have been discovered just recently, but from all indications, they have been around for a very long time. At present, they are already being labelled as 'critically endangered'.
The Visayan warty pig can only be found on two of the Visayan Islands in the central Philippines, and as a result, faces unique challenges to their survival in the wild. The challenges include little room to escape from predators, 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.
Thanks to Veronica, I just remember that this is one of 6 kinds the native pigs they call baboy ramo or wild pig.
