Critically Endangered
Northern muriqui
Brachyteles hypoxanthus
Northern muriqui is a New World monkey in the family Atelidae (order Primates) — Brachyteles hypoxanthus, recorded as Critically Endangered and tied to Brazil.
Appearance
Northern muriquis can be individually recognized by their natural markings and facial features, such as fur color and patterning, ear shape, and face shape and pigmentation. Their diets, travel patterns and reproductive cycles are seasonally determined.
Although southern muriqui exhibit sexual dimorphism in canine length, northern muriqui show none.
Range and habitat
This species is endemic to the Atlantic Forest region of Brazilian states of Rio de Janeiro, Espírito Santo, Minas Gerais and Bahia.

Diet and breeding
This affect how groups of B. Hypoxanthus travel as they forage for food, as bigger family groups need to travel further to attain adequate food sources. The muriqui also utilize vertical niches when foraging, as they can access all levels of forest, from the floor to the canopy.
Muriqui group home ranges overlap, so unrelated groups of muriqui will avoid each other by traveling to or foraging for food by using these niche levels. Females will on average be ready to mate at the age of nine, wherein they can copulate with several partners in order to conceive, even so, some males can be shown preferential treatment by females.
In crisis
The northern muriqui is a critically endangered species, counts put the living population under 1,000 mature individuals in the wild. B. Hypoxanthus is one of the world's most critically endangered primates, according to the IUCN Red List of Threatened Species. It is threatened by hunting and (in common with most other primates of the region) destruction and fragmentation of its Atlantic Forest habitat.
Among the scattered populations of northern muriqui, only one population, located in Caratinga, was determined in 2006 to be viable for the rest of the century. The estimated wild population of northern muriquis was raised from about 500 to 1000 individuals in 2005, due to new discoveries and research in other forests.
