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]
This is a list of the native wild mammal species recorded in South America. South America 's terrestrial mammals fall into three distinct groups: "old-timers", African immigrants and recent North American immigrants.
The species is also believed to be present in Amazonas department in Colombia, and it may be present in Amapá, Brazil, in north Bolivia [16] and in southern French Guiana. [7] In 2024, the South American tapir was observed in the state of Rio de Janeiro for the first time since 1914. According to Marcelo Cupello, a scientist from Rio de ...
The Tapir Specialist Group, a unit of the IUCN Species Survival Commission, strives to conserve biological diversity by stimulating, developing, and conducting practical programs to study, save, restore, and manage the four species of tapir and their remaining habitats in Central and South America and Southeast Asia.
South America had no placental predatory mammals until the Pleistocene, and xenarthran large-mammal faunas may have been vulnerable to many factors including a rise in numbers of mammalian predators, resource use by spreading North American herbivores with faster metabolisms and higher food requirements, and climate change.
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia.They are natively found in Australasia, Wallacea, and the Americas.One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen.
The South American lungfish's genome was more than twice as big. The world's four other lungfish species live in Africa, also with large genomes. Lungfish genomes are largely composed of ...
Meridiungulata might have originated in South America from a North American condylarth ancestor, [3] and they may be members of the clade Laurasiatheria, related to other ungulates, including artiodactyls and perissodactyls. [4] It has, however, been suggested the Meridiungulata are part of a different macro-group of placental mammals called ...
