Get ready for some cuteness overload. The San Diego Zoo recently released photos of its newest addition, a baby red ruffed lemur born a few weeks ago at the zoo, the first lemur birth at the zoo in more than a decade.

The baby boy, who has not yet been named, was born May 18. He weighs 6.6 ounces and is gaining weight at a rate of about 10 grams a day. So far the baby appears to be thriving, and his mom — a first-time mother named Morticia — is doing an excellent job caring for him. Zookeepers expect him to begin exploring outside of his nest, with his mother close by, within his first month.

Since 1965, more than 100 lemurs have been born in captivity at the San Diego Zoo, but for the last 13 years, the facility has experienced a baby drought.

In the wild, red ruffed lemurs are only found on the Masoala Peninsula in Madagascar, and in such limited numbers that the species is listed as Critically Endangered by the International Union for Conservation of Nature (IUCN).

"Needless to say, the San Diego Zoo primate team is excited to welcome this little one to the world," said Kristen Watkins, a primate keeper at the zoo on the facility's website.

The lemurs at the San Diego Zoo are currently not on view to the public while they await the construction of a new Africa Rocks attraction. The exhibit is expected to open in the summer of 2017. In the meantime, you can follow the zoo's Twitter profile for updates on this little guy and all of the other critters that call the San Diego Zoo home.
