The 22-year-old animal's deteriorating health — kidney failure, arthritis and extreme weakness from muscle atrophy — led zoo officials to conduct the euthanasia procedure, according to a Honolulu Hale news release.

Born in October 1985 at an animal facility in Quebec, Canada, Apollo arrived at the Honolulu Zoo on April 17, 1986.

His pride consisted of two female lions. His genetic line was well-represented in the captive population and he never sired any offspring.

Lions live about 15 years in the wild. However, they can live well into their 20s in captivity because of the availability of medical treatment and a healthy diet.

"Apollo thrilled many visitors, as well as residents in the neighborhood, by declaring his territory with mighty roars every morning and evening. He'll be missed by everyone, but most of all by the zookeepers who cared for him throughout the years," zoo director Ken Redman said in the release.

Redman said the zoo will being searching for a young male lion to transfer to Honolulu.
