| | Zoo - Wikipedia, the free encyclopedia |
 | | The oldest still existing zoo, the Vienna Zoo in Austria, evolved from such an aristocratic menagerie founded in 1752 by the Habsburg monarchy and changed its face as well as its mission throughout the centuries. |
 | | Many zoos now have special buildings for nocturnal animals, with dim red lighting during the day, so the animals will be active when visitors are there, and bright lights at night to ensure that they sleep. |
 | | Many zoos have walk-through exhibits, where visitors enter enclosures of non-aggressive species, like lemurs, marmosets, birds, lizards, turtles etc. Visitors are normally asked to keep to paths, and animals are not tame. |
