Slow-down sloths, unscrupulous bats hanging upside down on your head, monkeys will never greet you, crocodiles and tigers will stare at their prey under the bridge you pass, kangaroos will swim with you. This feeling is what Singapore Zoo, one of the top ten zoos in the world, brings to visitors. Animals here are seldom caged or railed, and people can live comfortably and leisurely in this rainforest. People can get in touch with animals they like and live in harmony with them without any distance.
