The Columbus Zoo and Aquarium this week released the first photos of gorilla born Sept. 29.

On Thursday the zoo released photos of the lowland gorilla Cassie and her baby. Patty Peters, vice president of community relations, said they are the first photos staff has been able to get as Cassie has been taking good care of the month-old baby. The staff is still unsure of the baby's sex.

The new baby is being kept off view from zoo visitors along with father Annaka and three other members of the gorilla group while Cassie adjusts to being a mother.

This is the first baby for Cassie and the third for Annaka. The match was recommended by the Association of Zoos and Aquariums' Species Survival Plan for lowland gorillas.

The zoo doesn't know when Cassie and her new baby will be moved to an area in the African Forest habitat where visitors can view them.

Cassie's baby is the 13th gorilla to be born at the Columbus Zoo and Aquarium.
