Pygmy marmoset


Pygmy marmoset (Cebuella pygmaea)

The smallest monkey and yet not the smallest primate?

Pygmy marmosets reach a head to barrel length of 12-15cm and a weight of 100-120g. Therfore, they are still larger than e.g. mouse lemurs which is the smallest primate but are not counted as real monkeys. A group of pygmy marmosets consists of a couple and their (even adult) offspring. To avoid inbreeding the dominant couple suppresses reproduction of the other group members by hormones and aromatic substances.
