A tiny primate at the Columbus Zoo had an even tinier baby on June 9. Adult Pigmy Slow Lorises weigh one pound, so their babies weigh only a few ounces, but those little guys are ready to go! Loris babies are born fully-developed with open eyes, according to ZooBorns.

The Association of Zoos and Aquariums' Species Survival Plan played matchmaker to Gouda and Muenster, both first-time parents. The baby's gender is still unknown, but the tiny wonder is already climbing with mom (Gouda) in the zoo's nocturnal house.

These primates aren't monkeys; they belong to a group called prosimians, which includes lemurs, Lorises, aye-ayes, and tarsiers, according to the Duke Lemur Center. Slow Lorises may seem enchanting with their big, innocent eyes, but they produce a toxin from a scent gland on their elbow. If a Loris gets spooked, it will lick its elbow so the next animal it bites gets a dose of poison.

Pygmy Slow Lorises are native to Vietnam, Laos and Cambodia. During the Vietnam War, their habitat was devastated. They are listed as "vulnerable" by the International Union for Conservation of Nature.
