On June 18, tamarin mama, Annie, gave birth to healthy twins, one boy and one girl.
The twins are three to four inches in length and weigh 162 grams (girl) and 168 grams (boy).
The family is doing great, with dad, Mazzanti, and sisters, Sophia and Emilia, all pitching in to care for the babies, in a perfect display of characteristic tamarin behavior.
Youngest sister, Corky, is keeping her eye on everyone while she waits for her new playmates to grow a little bigger.
Check out our live Tam Cam to see how the babies are settling in.
