South America's considerable cervid diversity belies their relatively recent arrival. The presence of camelids in South America but not North America today is ironic, given that they have a 45-million-year-long history in the latter continent (where they originated), and only a 3-million-year history in the former. Family: Tayassuidae (peccaries)
Estimates, as of 2016, place their numbers around 1.5 to 2 million animals: 1,225,000–1,890,000 in Argentina, 270,000–299,000 in Chile, 3,000 in Peru, 150–200 in Bolivia and 20–100 in Paraguay. This is only 3–7% of the guanaco population before the arrival of the Spanish conquistadors in South America.
The fauna of South America consists of a huge variety of unique animals some of which evolved in relative isolation. The isolation of South America allowed for many separate animal lineages to evolve, creating a lot of originality when it comes to South American animal species. [ 1 ]

The fauna of the Andes, a mountain range in South America, is large and diverse. As well as a huge variety of flora , the Andes contain many different animal species. With almost 1,000 species, of which roughly 2/3 are endemic to the region, the Andes are the most important region in the world for amphibians . [ 2 ]
The original camelids of North America remained common until the quite recent geological past, but then disappeared, possibly as a result of hunting or habitat alterations by the earliest human settlers, and possibly as a result of changing environmental conditions after the last ice age, or a combination of these factors.
Furthermore, they also search for animal prey by turning over rocks on the ground or ripping open logs with their claws. [14] The South American coati was found to be a host of an intestinal acanthocephalan parasitic worm, Pachysentis lauroi. [15] Females typically live in large groups, called bands, consisting of 15 to 30 animals.
The first law addressing the capture and use of wild animals was contained in the Civil Code of 1888. [1] Chile has brought nearly 20% of its terrestrial area under conservation protection laws and 3.19% of its marine jurisdiction is also under protection. The first national park was created in 1925 following an earlier protected area created ...
