Thomas’s silky anteater

(Cyclopes thomasi)

other common names

Thomas’s pygmy anteater


Order: Pilosa
Family: Cyclopedidae


Until recently, it was thought that there was only a single species of silky anteaters. However, a 10-year long investigation by Miranda et al. (2018) provided evidence that there are actually seven species of Cyclopes.

No specific data are available on the size of Cyclopes thomasi, but assuming that it is similar in size to other silky anteaters, it would have a head-body length of around 20 cm, a tail of similar length, and it would weigh around 300 grams. The fur of its body is strikingly orange to reddish brown, while the legs and tail are grey. There is no dorsal stripe, and the ventral stripe is little developed and faint.


Cyclopes thomasi is distributed in western Brazil and east central Peru; it has been recorded in the western Amazon Basin, from Rio Juruá southwest to the Río Ucayali Region. Its eastern limits are unknown.


No data are available on the habitat and ecology of this arboreal species.
