The zoo was founded in 1968 by Sheikh Zayed bin Sultan Al Nahyan, the late Ruler of Abu Dhabi and President of the United Arab Emirates, out of concern for the land's wildlife, particularly ungulates such as the Arabian oryx. The zoo features a big cat house. Lions, cougars, jaguars, and black and spotted leopards are found here. In addition to this, it also has a reptile house, monkey compounds, aquarium, and aviary. From February 2010 until July 2010, the Al Ain Zoo hosted the "Dinosaur Trail", a small section which includes around 15 to 20 mechanical dinosaurs with sensors such as Tyrannosaurus rex, as well as information about the dinosaur such as when they lived, which parts of the world they would have been found, and their height and diet, for example. There is a bird show featuring predatory birds and night birds that lasts 30 minutes starting at 7 pm. The dinosaur trail is open until 8 pm. Wheelchairs are available on request. To walk aroundthe zoo and see all the animals, besides the Dinosaur Trail, would take approximately 2 hours. The zoo also has a "train" with open carriages. It does not enter the "yellow" section which hosts the African lion, Bengal tiger, chimpanzee, puma, saltwater crocodile, panther, Nile crocodile, and leopard. The zoo is home to over 4,000 animals, with at least 30% of its 180 species considered endangered. Conservation efforts have been strengthened by partnerships with San Diego Zoo. This park near the base of Jebel Hafeet is where visitors can see a large animal collection in enclosures that closely resemble their natural habitats. There are plenty of green public spaces for picnics and also playgrounds, a cafeteria and a train tour of the wildlife area. Giraffe feeding, camel riding and 'Elezba' petting zoo are the latest interactive activities. Visitors can enjoy feeding the giraffe treats such as carrots or lettuce five times daily in a special area. Designed in the style of a local farm, the 'Elezba' petting zoo lets families feed and play with sheep, goats, camels, llamas, chicken and ducks, enjoy camel riding or picnic in a designated area. A fun-filled, outdoor learning scheme designed to inspire children with a love for biodiversity, this garden beauty of plants. The garden features a rolling hill, mixed-use play areas, picnic spots, a flower garden and native plant garden with species indigenous to the UAE, a recycling garden and a vegetable, fruit and herb garden. With spectacular African Baobab trees framing the area, the towering trunks offer a genuine horticulture lesson in how specific plants can adapt to dry soil conditions. As of April 2019, the zoo is preparing to expand with work on its perimeters going on at the moment in order to build new sites such as the conservation and breeding centre, African Safari, World Desert Zoo, and the Sheikh Zayed Desert Learning Centre.
