"The Smallest Anteater" (The Silky Anteater, Cyclopes didactylus dorsus)
This anteater is slow-moving and largely arboreal, much like their sloth cousins. However, they also have a partially prehensile tail, and eat, well, ants. Sometimes they also eat other insects that pass by them, but they don't produce chitinase, so they can't fully digest those bugs.
