Dublin Zoo manages the EEP for the golden lion tamarin and the Moluccan cockatoo. Golden lion tamarin groups exhibit cooperative rearing of the infants. The mating system of the golden lion tamarin is largely monogamous. These predatory attacks occur at the golden lion tamarin sleeping sites. Predators of the cotton-top tamarin include snakes, ocelots, tayras, and most notably, hawks. The golden lion tamarin is the largest of the callitrichines.

"S. oedipus" has the common names "cotton-top tamarin" and "cotton-headed tamarin" in English. The face of the black tamarin is generally hairless.
