The Daily Species #17:
Chacoan Peccary (Catagonus wagneri)
The Chacoan peccary or Tagua is a species of peccary found in the Gran Chaco of Paraguay, Bolivia and Argentina. It is the largest of the three living species of peccary, but only about 3000 exist in the world. It is believed to be the closest living relative to the extinct genus Platygonus.
The Chacoan Peccary has the unusual distinction of having been first described in 1930 based on fossils and was originally thought to be an extinct species. In 1975 the animal was discovered to still be alive in the Chaco region of Paraguay. The species was well known to the native people, but it took a while for scientists to rediscover its existence. It is known locally as the Tagua.
