Southern Muriqui Brachyteles arachnoides

The Muriqui or Woolly Spider Monkey is the largest New World primate and has recently been divided into two subspecies, the main difference between the two being the presence of a small thumb in the Northern variety. It may eventually be shown that they are seperate species.

Endemic to the Atlantic forests of Brazil, Muriquis are found in low lying areas from sea level to around 1,000m. Their long limbs and prehensile tails enable them to be particularly agile amongst the trees.

Muriquis, were once widespread throughout the Atlantic forests, but today only a handful of small populations survivein protected areas. Muriquis are not only threatened by habitat destruction and fragmentation but have also suffered from excessive hunting for food in the past.

The Northern Muriqui is classified as Critically Endangered by IUCN (See IUCN Red List of Threatened Species for more information on the classification of the Northern Muriqui).

The Southern Muriqui is classified as Endangered by IUCN (See IUCN Red List of Threatened Species for more information on the classification of the Southern Muriqui).
