There are two adorable new creatures to see at the Prospect Park Zoo: A set of Geoffroy's marmoset twins, born last November, are now on display! (And way more viral than the last animals they acquired.)

The twins were born to Gordon, a 2-year-old male, and Xing, a 3-year-old female, who came to the zoo last year. The Wildlife Conservation Society said that this is the first set of Geoffroy’s marmosets, which are native to the Atlantic rainforest in eastern Brazil, born there.

You can see the whole family at the Animal in Our Lives building.
