The first gorilla ever born in captivity celebrated her 56th birthday on Saturday.
The Columbus Zoo and Aquarium treated Colo and the other gorillas to a special cake. She also received her favorite treat, tomatoes.
Colo was born at the zoo in 1956. Assistant African Forest curator Audra Meinelt said the primate is the oldest gorilla at any zoo.
"We are just lucky she is doing so well. The median life expectancy for a gorilla is 37.4 years, and she's made it 56. She's in extremely good health and we're just very fortunate here," Meinelt said.
The zoo included visitors in the celebration by offering cake to the human guests and inviting them to sing "Happy Birthday."
Meinelt said Colo is a mother of three, as well as a grandmother, great-grandmother, and great-great-grandmother with more than 24 descendants.
