Check in on the Saginaw Children's Zoo cotton-top tamarins anytime! Clementine, 11, and Gizmo, 7, are a mating pair of the critically endangered species that are native to Colombia. They were matched at the zoo in 2012 through a cooperative breeding program and bonded quickly. In February 2016, Clementine gave birth to a set of healthy twins, sisters Pax and Bean. The zoo lost Bean, but the tamarin family is holding up well. Cotton-top tamarins can live 10-15 years in the wild and 20 years in human care.
