The black tamarin (Saguinus niger) occurs in all states of Brazil, including large urban centers due to population growth. Considering that the practice of medicine and surgery on wild animals has become more prevalent in veterinary medicine, this work describes the aortic arch of S. niger with the goal of aiding emergency surgeries. Four animals were studied. Three individuals had an aortic arch like the arch described for domesticated animals, including the presence of a left subclavian artery and brachiocephalic artery. In one individual, the arrangement of the collateral branches of the aortic arch followed the pattern found in humans, including the presence of a brachiocephalic artery, left common carotid artery, and left subclavian artery. Regardless of the initial configuration of the aortic arch of the black tamarin, the right subclavian, right vertebral, right internal thoracic, right costocervical and right superficial cervical arteries arose, sequentially, from the brachiocephalic artery. The branches formed by the left subclavian artery correlated with the right antimer.
