  • The species’ tail is non-prehensile and relies on the strength of its arms and legs to transport itself from one branch to another.
  • The equatorial Saki is sexually dimorphic.
  • It is sometimes confused with the monk saki, but the equatorial Saki’s reddish throat and chest set it apart from others.
