Geoffroy's marmoset is a small monkey with a white front part of the head and black tufts on the ears. It lives in trees in the forests of eastern Brazil and feeds on various foods.
Geoffroy's marmoset differs from related species with a bright white front part of the head and black ear tufts. It is important for the forest because it disperses plant seeds and eats many insects.
