First nocturnal zoo
Singapore Night Safari
Singapore ()

Opened to the public on 3 May 1994, Singapore Night Safari is the world's first zoo that opens exclusively at night. The site occupies around 35 hectares (86 acres) of secondary rainforest in Singapore and is home to around 900 animals representing more than 100 species that are most active during twilight and night.

Crepuscular and nocturnal species found at the zoo include Asian elephants, Malayan tapirs, bats, deer, pangolins, tarsiers and fishing cats. The animals are made visible thanks to artificial moonlight, which although brighter than natural moonlight is still dim enough not to disturb them from their night-time activity.

The concept behind the night-only zoo originated with Dr Ong Swee Law, who previously was chairman at the nearby Singapore Zoo.
