First opened to paying visitors in 1847, the world famous London Zoo and Conservation Centre currently houses over 12,000 mammals, birds, reptiles, fish and insects, including a number of rare and endangered species. It is an embarrassment of riches including Gorilla Kingdom and the reptile house as well as enclosures for lions, spider monkeys, Komodo dragons and meerkats. The Penguin Beach exhibit features England's largest penguin pool. The tropical splendour of Butterfly Paradise surrounds visitors with beautiful species from across the globe, including Africa, Central and South America. See how these stunning creatures finally emerge in the Pupae and Breeding Room, and find out more about the importance of the plants within this section of the zoo. The Clore Rainforest Lookout is a new attraction, comprising a South American rainforest beneath a translucent roof, which creates the necessary humidity for the tamarins, birds and marmosets that live here. A children's area called Animal Adventure gives visitors the chance to learn more about red pandas, donkeys, Nubian goats, llamas, the red-legged seriema and other fascinating breeds. As well as enjoying the animals in their habitats, the zoo inspires youngsters to make a difference through its many conservation projects.
