Chacoan peccary

The Chacoan is the largest (by size) species of peccary, a beast that resembles a pig but hails from a different continent and cannot be domesticated. The Chacoan peccary was first described in 1930 based only on fossil records, and was believed to be extinct. Then in 1975, surprised researchers discovered one alive in the Chaco region of Paraguay. Today there are around 3,000 known individuals.
