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]

Unfortunately, the bulk of sloth species that once roamed the earth -- some of which grew to be the size of elephants -- cannot say the same. Long ago, there Sloths were once as large as elephants
The species was discovered by John Edward Gray in 1850, but his assertions were later dismissed, with taxonomists agreeing that the specimen, that Gray described was a B. torquatus, but the new study proves that B. critinus does indeed exist. [1] The B. crinitus separated from B. torquatus in the north by more than 4 million years of evolution. [3]
