Life Of Animals In Zoo

Human beings were also displayed in cages during the 1931 Paris Colonial Exposition, and as late as 1958 in a "Congolese village" display at Expo '58 in Brussels.
Appearance and type
Zoo animals usually live in enclosures that attempt to replicate their natural habitats, for the benefit of the animals and the visitors. They may have special buildings for nocturnal animals, with dim white or red lighting used during the day, so the animals will be active when visitors are there, and brighter lights at night to help them sleep. Special climate conditions are created for animals living in radical environments, such as penguins. Special enclosures for birds, insects, reptiles, fish, and other aquatic life forms have also been developed. Some zoos have walk-through exhibits where visitors enter enclosures of non-aggressive species, such as lemurs, marmosets, birds, lizards, and turtles. Visitors are asked to keep to paths and avoid showing or eating foods that the animals might snatch.
