The Sacramento Zoo says three newborn baby lemurs are doing well.
Two Black and White Ruffed Lemurs were born two weeks ago. A rust-colored Mongoose Lemur was born Tuesday.
The zoo's Tonja Candelaria says the infants of each species have a different approach to growing up.
"The two Black and White Ruffed Lemur girls are thriving and they're growing at a wonderful rate. They're nesting out in an off-exhibit space just as they would in the wild. The Mongoose Lemur infant is hanging on tight to mom, which is exactly what it's supposed to be doing. It rides around her waist like a fanny pack."
Candelaria says both species are native to Madagascar and are critically endangered.
There are between 1,000 and 10,000 of each species remaining in the wild.
The zoo now has seven black and white lemurs and three Mongoose Lemurs.
