The silky anteater, or pygmy anteater, (Cyclopes didactylus) is a species of anteaters from Central and South America, the only living species in the genus Cyclopes and the family Cyclopedidae. A single extinct cyclopedid genus, Palaeomyrmidon, known from the Miocene of Argentina, may be ancestral to the living species.
Silky anteaters are the smallest living anteaters, and have proportionately shorter faces and larger crania than other species. Adults have a total length ranging from 36 to 45 cm (14 to 18 in), including a tail 17 to 24 cm (6.7 to 9.4 in) long, and weigh from 175 to 400 g (6.2 to 14.1 oz). They have dense and soft fur, which ranges from grey to yellowish in colour, with a silvery sheen. Many subspecies have darker, often brownish, streaks, and paler underparts or limbs. The eyes are black, and the soles of the feet are red.
The scientific name translates roughly as "two-toed circle-foot", and refers to the presence of two claws on the fore feet, and their ability to almost encircle a branch to which the animal is clinging. The claws are present on the second and third toes, with the latter being much the larger. The fourth toe is very small, and lacks a claw, while the other two toes are vestigial or absent, and are not visible externally. The hind feet have four toes of equal length, each with long claws, and a vestigial hallux that is not externally visible. The ribs are broad and flat, overlapping to form an internal armoured casing that protects the chest.
They have partially prehensile tails.
Silky anteaters are found from Oaxaca and southern Veracruz in Mexico, through Central America (except El Salvador), and south to Ecuador, and northern Peru, Bolivia, and Brazil. A smaller, isolated population is also found in the northern Atlantic Forest of eastern Brazil, and there are also silky anteaters on the island of Trinidad. They inhabit a range of different forest types, including semideciduous, tropical evergreen, and mangrove forests, from sea level to 1,500 m (4,900 ft).
