The three-toed or three-fingered sloths are arboreal neotropical mammals. [2] They are the only members of the genus Bradypus (meaning "slow-footed") and the family Bradypodidae. The five living species of three-toed sloths are the brown-throated sloth, the maned sloth, the pale-throated sloth, the southern maned sloth, and the pygmy three-toed ...
The pygmy three-toed sloth is unique in that it is found exclusively in the red mangroves of Isla Escudo de Veraguas; the island has a small area of approximately 4.3 square kilometres (1.7 sq mi). A 2012 census of pygmy three-toed sloths estimated the total population at 79 – of which 70 occurred on mangroves and 9 in the surroundings.
The pale-throated three-toed sloth (Bradypus tridactylus), which inhabits tropical rainforests in northern South America. It is similar in appearance to, and often confused with, the brown-throated three-toed sloth, which has a much wider distribution. Genetic evidence indicates the two species diverged around six million years ago. [10]
The brown-throated sloth is of similar size and build to most other species of three-toed sloths, with both males and females being 42 to 80 cm (17 to 31 in) in total body length. The tail is relatively short, only 2.5 to 9 cm (1.0 to 3.5 in) long.
The Maned three-toed sloth is considered the most endangered of all of the sloth species and they are listed under the Vulnerable (VU) category according to the IUCN Red List. [2] Due to hunting and anthropogenic deforestation consistently occurring, the sloth species was reduced to about 7% of their original habit in the Atlantic Forest.

Three-toed sloths (Bradypus) Megatheriidae is suggested to have diverged from other sloth families during the Oligocene , around 30 million years ago. [ 24 ] The subfamily to which Megatherium belongs, Megatheriinae , first appeared in the Middle Miocene in Patagonia , at least 12 million years ago, represented by the genus Megathericulus . [ 25 ]
The pale-throated sloth (Bradypus tridactylus), occasionally known as the ai (/ ˈ ɑː i /), [4] is a species of three-toed sloth that inhabits tropical rainforests in northern South America. It is similar in appearance to, and often confused with, the brown-throated sloth, which has a much wider distribution. Genetic evidence has been ...
