The main viewing of the zoo's eight western lowland gorillas.
The Gorilla World exhibit opened in 1978 as the first naturalistic gorilla habitat in the United States. The exhibit is complete with waterfalls, large trees, and ways on how guests can help save gorillas. The Cincinnati Zoo currently has had the most gorilla births than any other zoo in the country with 48, the last being in 2006. In 1996, six gorillas were born, the most in one year. The first test tube gorilla, Timu, was born at the zoo as-well in in 1995. Due to many breeding efforts, the zoo was named the "Sexiest Zoo in America", by Newsweek. Currently eight gorillas reside at the zoo.
