The Neotropic realm consists of South America together with Central America, the Caribbean and southern Florida. The realm consists all different climate zones; tropical forests, the highlands of the Andes, and the South American plains, extending to Antarctica.
While the llama (Lama glama) is the domestic form of the guanaco, the alpaca (Vicugna pacos) is the domestic form of the Vicuña (Vicugna vicugna). These are closely related to camels, and were the only large livestock animals in pre-Columbian America.
The jaguar (Panthera onca) is the largest big cat in the Americas and is the third largest in the world after the tiger and lion.
The cougar (Puma concolor), also known as the mountain lion, puma, panther, or catamount, is widespread across the Americas.
New World monkeys (Platyrrhini) are the monkeys of Central and South America; most of them living in the Amazonas. Some of them are very small; the Pygmy marmoset (Cebuella pygmaea) weighs only 100 grams as an adult. They form a distinct group from the Old World monkeys of Asia, Europe and Africa; Old World monkeys are more closely related to humans than to New World monkeys.
