Pissinatti’s saki^[1], or Pissinatti’s bald-faced saki (Pithecia pissinattii), is a controversial species of saki monkey, a New World Monkey.

• Both sexes have pink to dark red faces, with older females’ faces tending towards black, and they also have black fur with a distinctive gray tinge.
• Male species have a distinctive orange frill; younger males are very gray, but older males are not as gray.
• Females have a lighter brown and grayer back.

• This species is named after Alcides Pissinatti, a Brazilian veterinarian who pioneered the breeding of endangered Brazilian primates.
• Pissinatti’s saki is native to Brazil and is found south of the Solimões river between the Madeira and Purús rivers.
• This species is believed to be threatened by deforestation and poaching, and its population is declining.
• Pissinatti’s sakis are very arboreal, rarely reaching the ground, and primarily use quadrupedal locomotion in the trees.
• These sakis often use vocalizations to communicate with their peers and to defend territorial boundaries.
