The Columbus Zoo & Aquarium welcomed a new bonobo Dec. 28.

As staff members arrived to work Tuesday morning, they discovered the anticipated birth of a baby bonobo had occurred, according to a news release from the zoo.

The baby, whose sex currently is unknown, is the 12th bonobo born at the zoo since 1990, when the zoo received the smallest species of great apes.

Bonobo "Ana Neema" carried the baby for 8 1/2 months, and the baby is her third. The baby and mother are being kept out of view to allow for bonding.
