There is no need to be a busy bee today; it is the perfect moment to be slothful. Happy International Sloth Day! Perhaps don't get too comfortable doing nothing; the ovation is for our furry friends. The messy hairstyle and friendly face of this pygmy three-toed sloth in today's image might make you want to join the branch party, but these animals are not at all easy to find. Also known as the monk sloth or dwarf sloth, the species is endemic exclusively to a small island off the Caribbean coast of Panama, Isla Escudo de Veraguas. This species is significantly smaller than other kinds of sloths. They are about 50 centimetres in length and weigh between 2.5 to 3.5 kilograms. Sadly, the pygmy three-toed sloth is classified as critically endangered on the International Union for Conservation of Nature's list.
