Lesser bushbabies are small, woolly primates with long tails and oversized, naked ears. Different species are sometimes indistinguishable even when compared side by side.[4] Additionally, there is often notable variation in coloration and body size even within species and populations.[5] Their coat varies across body regions as well as between species, typically ranging from black, brown, and grey to white, with many showing a greenish, reddish, and orangeish tint to the sides and limbs. Some species have a nasal strip while others have distinct dark rings around the eyes.[4]
