Key Questions Answered

The pygmy three-toed sloth, scientifically named Bradypus pygmaeus, is the world's rarest sloth and is found exclusively on Isla Escudo de Veraguas, a tiny island off Panama's Caribbean coast.

The pygmy sloth is smaller than its mainland relative due to a process called island dwarfism, where animals evolve smaller bodies after developing in isolation on a restricted island environment.

The species faces threats from habitat loss, mangrove cutting, littering, and growing tourism pressure on its small island home.
