Lulu, a 46-year-old western lowland gorilla, died at the Columbus Zoo and Aquarium this week.

The gorilla, who suffered from arthritis, had a seizure on Jan. 22, a news release from the zoo said.

"The frequency and severity of the seizures progressed and on Monday, Jan. 24, while being sedated in preparation for an MRI she stopped breathing and could not be resuscitated," the release said.

An autopsy is being performed.

Lulu was born in Africa and at age 2 was brought to the Central Park Zoo in 1966. In 1984, Lulu came to the Columbus zoo, where she had three babies.

Lulu was also a member of the zoo's gorilla surrogacy program and mothered two infants.

"When she came to the Columbus Zoo our first impression of Lulu was she was one tough lady," animal care and conservation vice president Dusty Lombardi said in the release, "but it wasn't long before she showed us her sweet maternal side. She was also fun-loving and enjoyed playing hide and seek with her keepers."

Zoo staff invite the public to share memories of Lulu on the Columbus Zoo Facebook page.
