The bald uakari^[1] is an Amazon primate with special traits: it has a glossy red bald face, a short tail, and reddish fur. This monkey is highly specialized and is mainly found in palm habitats.

• The species are most easily recognized by its bald head and red face, from which it takes its name.
• Some people compare them to babies and older people because of their baldness; it is undeniable that these species are of outstanding beauty.
• Another notable feature that characterizes the bald uakaris is their prominent short tail, only about 52 cm long.
• They do not use their tails to move between trees; they depend on their legs, arms, and long hairy toes and fingers. Their fur coats are long and cover their entire bodies.

• The conspicuous crimson color is caused by blood flow under the skin, specifically, a thinner epidermis with a higher concentration of capillaries on the face.
• A 2016 study found that the bald uakari has a highly polymorphic color vision. Researchers believe this helps them when foraging when they need to be able to tell the colors of food against a background of leaves.
• Females tend to reach sexual maturity at three years of age before males become sexually mature at six.
• The species is an herbivore but is so dependent on fruit for food that some might more accurately classify the species as a frugivore.
• The troop is significant, often up to 100 monkeys, but more commonly around 30. The largest troop divides into small groups for feeding, with each sub-group containing up to 10 monkeys.
