Red River Hogs

In a photo provided by the San Diego Zoo, two male red river hogs make their debut Monday, May 1, 2006, at the San Diego Zoos Wild Animal Park. The piglets and their parents can be seen in the Nairobi Village. The red river hog is found in Africa. It is named for its reddish brown fur, and the fact that it often wades through water. These pigs are active both day and night and are good swimmers, holding their tails above the water. They can also swim underwater, catching a breath every 15 seconds or so.
