A zoological garden, zoological park, or zoo is an institution where mainly wild and exotic animals are restricted within enclosures, bred and displayed to the public.

Most of today’s non-profit and serious zoological gardens display wild animals, not just for the amusement and the entertainment of their visitors, but primarily for conservation of endangered species, for education and biological research.
The concern of these institutions is to help save the diversity of life on Earth through applied conservation activities such as breeding endangered species.
The breeding of endangered species is coordinated by cooperative breeding programmes containing international studbooks and coordinators, who evaluate the roles of individual animals and institutions from a global or regional perspective..
