Linnaeus's two-toed sloth (Choloepus didactylus), also known as the southern two-toed sloth, unau, or Linne's two-toed sloth is a species of sloth from South America, found in Venezuela, the Guyanas, Colombia, Ecuador, Peru, and Brazil north of the Amazon River.

The aardvark (Orycteropus afer) is a medium-sized, burrowing, nocturnal mammal native to Africa. Unlike other insectivores, it has a long pig-like snout, which is used to sniff out food. It roams over most of the southern two-thirds of the African continent, avoiding areas that are mainly rocky. A nocturnal feeders, aardvarks subsist on ants and termites, which they will dig out of their hills using its sharp claws and powerful legs. Aardvarks also dig to create burrows in which to live and rear their young.

The Chinese pangolin (Manis pentadactyla) is a pangolin found in northern India, Nepal, Bhutan, Bangladesh, Myanmar, northern Indochina, through most of Taiwan, and southern China.

The Brazilian three-banded armadillo (Tolypeutes tricinctus) is an armadillo species endemic to Brazil, where it is known as tatu-bola (lit. ball armadillo). It is one of only two species of armadillo (the other is the southern three-banded armadillo) that can roll into a ball.
