common marmoset
(Callithrix jacchus)


Atlantic coastal forests of north-eastern Brazil.

biological characteristics

Marmosets have long limbs and tail for climbing, and specially-designed teeth for extracting gum from trees. They have an opposable thumb that aids them, as they are branch runners and springers. They are hand-over-hand climbers, and use their tail for support and balance. Marmosets vocalise in a very high-pitched squeaky call as well as chirps and clicks.

conservation status

Listed as Least Concern (IUCN red data list).


  • They defend their home ranges by marking them out with a substance from their scent glands on their chests. When threatened, males will turn and show their genitalia.
