Pygmy Three-toed Sloth

Bradypus pygmaeus

Critically Endangered

At extremely high risk of imminent extinction in the wild.

Spotted something wrong?

The pygmy three-toed sloth is one of the most threatened mammals in the world and lives only on Isla Escudo de Veraguas, a Panamanian islet of little more than four square kilometres. It is a textbook case of insular dwarfism: it is around 40% smaller than the mainland three-toed sloth from which it separated some 9,000 years ago, when rising sea levels isolated the island. It feeds almost exclusively on red mangrove leaves, a resource very poor in energy.

Fun facts

  • conservaciónIt is critically endangered and confined to a single island off the coast of Panama, with a total population estimated at a few hundred.
  • It separated from its mainland relatives barely 9,000 years ago, when rising sea levels after the last glaciation cut off its islet: it is a very young species in evolutionary terms.
  • It swims well among the mangroves, and its fur harbours green algae that camouflage it among the foliage and give it a characteristic greenish tinge.
