Pygmy Three-toed Sloth

Bradypus pygmaeus

Also known as Monk Sloth, Dwarf Sloth

Inhabiting the dense red mangrove canopy of a single island off the coast of Panama, pygmy three-toed sloths move with remarkable deliberation through the branches. Symbiotic green algae growing within specialized grooves on their fur provides built-in camouflage while nourishing a unique community of resident insects. Their extraordinarily slow metabolism relies on digesting tough foliage, keeping these quiet arboreal mammals tethered to their fragile island ecosystem.
