The Zoo, which opened to the public in 1847, covers 36 acres. It's home to more than 760 animal species, many of which are endangered – your entry fee contributes to ZSL London Zoo's conservation projects across the globe.
A paradise pad for the pygmy hippos complete with heated pools and landscaped gardens has become the home of 17 year old Thug and his 19 year old girlfriend Nicky. They have joined the giraffes, zebras and hunting dogs in the zoo’s Into Africa exhibit. In 2013, the zoo opened Tiger Territory, a £3.6m Indonesian-inspired habitat designed to meet all the sensory needs of its inhabitants, including newest zoo arrivals Jae Jae and Melati, a pair of Sumatran tigers. It joined other recent highlights such as 'Gorilla Kingdom', where you can get surprisingly close to the zoo's colony of Western Lowland gorillas, and the penguin habitat, where you can enjoy feeding time for the colony of Macaroni and Humboldt penguins. 'Rainforest Life' recreates a tropical forest, in which are hiding Red Titi monkeys, marmosets, tamarins and sloths. It leads down to 'Night Life', filled with nocturnal creatures including scorpions and the slender loris (a tiny sad-eyed primate). The Zoo's butterflies are housed in a giant caterpillar-shaped walk-through haven. Visitors to Butterfly Paradise can spot more than 30 different species including delicate glasswing butterflies and giant atlas moths.
The lemurs were treated to a habitat makeover earlier this year, and their new sun-filled pad is a walk-through exhibit, allowing humans to get up close and personal. The boisterous troop is made up of 16 handsome bachelors. See if you can spot the black and white ruffled odd-one-out against the 15 ring-tailed look-alikes. Also new for 2015 (opening May 23) is In with the Spiders, a walk-through exhibit which sees visitors coming eye-to-eyes with the eight-legged creatures.
Across the site, regular events include 'animals in action' displays, feeding sessions, keeper talks and the glorious sight of birds in flight on the display lawn. There are also plenty of cafés and picnic spots, and the zoo offers educational and craft activities, as well as an ongoing programme of exhibitions exploring science and conservation.
