London Zoo is the oldest among all public zoos in the world. It was founded on April 27, 1828. This zoo is not the largest in size, but has a large collection of animals, with 700 species and more than 16,000 individuals. Interestingly, the first zoo was designed exclusively for research Zoological Society of London and was closed to the public. However, the expanding collection of rare species, many of which had not yet been widely known, led the founders to open the zoo to see in 1847.Among the first inhabitants of the zoo were such rare species as the Arabian oryx, kudu antelope, orangutans and even extinct today Quagga and marsupial wolves. Initially, all pets zoo kept indoors. It was believed that raw climate is unfavorable for the inhabitants of London hot countries. In 1902, Secretary of the Zoological Society of London, Peter Mitchell held a large-scale reorganization, due to which many of the animals are living in open-air cages. This did not harm them, but also contributed to the prosperity of many species. Since then, the London Zoo is constantly modernizing the exposition and business premises. Modern London Zoo — one of the world centers for the breeding of endangered species.Now London Zoo includes the main exhibition, which features large mammals and birds, a pavilion for parrots and tropical birds, terrarium, aquarium and insectarium.
