The Goeldi's monkey is an excellent long jumper that can leap several meters from branch to branch. Interestingly, its distribution area overlaps with other marmoset species in dense forest areas, but it is always far away from other groups of Goeldi's monkeys. This makes the search for a sexual partner difficult and the risk of inbreeding high. This is probably why not only the highest-ranking female reproduces, as is usual with marmosets.
The Goeldi's monkey was only scientifically described in 1904 and named after the Swiss zoologist Emil August Goeldi.
