- the largest of the peccary species (Catagonus wagneri), the only living member of the genus Catagonus, found in the hot, dry Gran Chaco region of South America, differing from other peccaries with its longer tail, snout, and ears: first identified by fossils in the 1930s and believed to be extinct, it was found in the 1970s to be living and is now listed as an endangered species owing to habitat loss and herd fragmentation.
