The pied tamarin (Saguinus bicolor), sometimes referred to as the Brazilian bare-faced tamarin, is a Critically Endangered primate species found in a restricted area of the Brazilian Amazon Rainforest. It was named the mascot of Manaus, Brazil in 2005. The species is endangered due to the increasing size of the city of Manaus which is encroaching on their native habitat. The pied tamarin's body measures 20.8–28.3 cm.; including the tail it measures 33.5–42.0 cm. The tamarin has a brown lower body and a fluffy white upper body. Their face is black and hairless, the reason for its nickname: the Brazilian bare-faced tamarin. The pied tamarin does not have nails, but instead has claws that they adapted in order to quickly scale trees in order to retrieve food or escape predators. These nails also allow the tamarin to dig into tree bark and extract sap which they then eat. Males weigh 428 grams (n = 4). Its life expectancy is approximately 10 years in the wild.
