After dinner, we went with S to the Night Safari! This is one of Singapore's signature tourist attractions. We saw a night show, road a train around to see the nocturnal animals active at night, and also could walk around to some of the close animals. The whole place was designed like a forest and it was hard to find fences marking that the animals were caged. It was truly amazing but hard to take photos of.Unlike traditional nocturnal houses, which reverse the day-night cycle of animals so they will be active by day, the Night Safari is an entire open-air zoo set in a humid tropical forest that is only open at night. It is divided into eight geographical zones, which can be explored either on foot via three walking trails, or by tram. The animals of the Night Safari, ranging from Indian rhinoceros to tarsiers, are made visible by lighting that resembles moonlight. Although it is brighter than full moonlight by a few orders of magnitude, it is dim enough not to disturb nocturnal and crepuscular animals' behaviour. London based lighting designer Simon Corder created the lighting for Night Safari. Exhibits in the safari come from South America and other parts of Asia. The naturalistic enclosures simulate the animals' native habitat. Animals are separated from visitors with natural barriers, rather than caged, similar to the Singapore Zoo's open concept. Instead of vertical prison-like cages, cattle grids were laid all over the park to prevent hoofed animals from moving one habitat to another. These are grille-like metal sheets with gaps wide enough for animals' legs to go through. Moats were designed to look like streams and rivers to enable fishing cats and servals to be put on show in open areas, and hot wires were designed to look like twigs to keep animals away from the boundaries of their enclosures.
