Smallest species of sloth

With a head and body length of around 48–53 centimetres (18.8–20.8 inches) – the tail adds an extra 4–6 centimetres (1.5–2.4 inches) – the pygmy three-toed sloth (Bradypus pygmaeus) is the smallest member of the sloth family. This critically endangered species is found in mangroves on a single island off the coast of Panama: Isla Escudo de Veraguas.

An adult pygmy three-toed sloth weighs in the region of 2.5–3.5 kilograms (5 pounds 8 ounces–7 pounds 11 ounces).

With an estimated population of less than 300 left in the wild, the pygmy three-toed sloth is also the rarest sloth.
