Gladys Porter Zoo is a zoological and botanical park located in Brownsville, Texas.
The zoo officially opened on September 3rd 1971, and currently averages
375,000 visitors annually. Situated on 31 acres (13 ha), the zoo houses
about 400 animal species (including 47 endangered species) and over 250 tropical and neo-tropical species and subspecies. It is the first zoo to have successfully bred the vulnerable Jentink's Duiker. Arriving from Omaha's Henry Doorly Zoo in July 1970, Katanga and Lamydoc were the first gorillas to be imported to Gladys Porter Zoo. They were the parents of the first ever baby gorilla, Bruno, a hand reared male born on September 1st 1972.
The area dedicated to gorillas at Gladys Porter Zoo has two outdoor enclosures. One of them (considerably larger and where the family group is exhibited) has the structure of an island surrounded by a water moat all around it. Trees and climbing structures are provided on both them. The backstage area where the night bedrooms are located at is off-exhibit.
