The muriquis, or woolly spider monkeys, are the genus Brachyteles. There are two species, the southern (B. arachnoides) and northern muriqui (B. hypoxanthus) muriquis. The name "muriqui" comes from a native Tupi word meaning 'largest monkey'.

The adult muriqui is 15-23 inches (38–58 cm) long and weighs from 10-20 pounds (4.5-9 kilos) They are colored from brown to black and the bottom of their tails have no fur near the end.
Muriquis live in groups from four to 43. They do not fight about their territory. They mostly eat leaves. They sometimes eat fruit and flowers in the rainy season, as well as bark, bamboo, ferns, nectar, pollen, and seeds.
