Uakari

The Uakari Has short back legs and smaller hands with long fingers For climbing trees which it does to escape predators and find food But The Amazon its natural habitat might not have as many trees in the future t=so it will have longer legs to go faster and larger hands to possibly fend off predators in groups. It also has a small jaw/mouth for the fruits and occasional insects it eats but with less trees there will be less fruit so a bigger jaw would help it eat more stuff. Also its orange-ish fur can blend in with trees but with no trees in its habitat a more brown fur will help it blend in with the dirt.
