Monkeys and Other Mammals
Visitors to the park do have to take certain precautions. Bring a hat, mosquito repellent, and most importantly, do not feed the monkeys or eat in their presence. These primates can be bold and aggressive, unlike the other mammalian inhabitants of the nature reserve, including a variety of bats, tree shrews, mice, squirrels and deer.
Snakes
If you're the snake enthusiast, this is the place for you. However, these elusive creatures are mainly nocturnal and some are also extremely dangerous. Many, such as the sunbeam snake, are harmless and beautiful. Others have a reputation for suffocation or deadly poison, including a number of species of pythons, pit vipers and cobras. Water-dwelling snakes such as sea snakes and coral snakes also inhabit the reserve.
Other Reptiles
This tropical island and rain forest climate is home to a large number of other reptiles, including turtles, lizards and crocodiles. The variety of turtles includes marine, soft shell, and both Asian and American terrapins. The different types of lizards include geckos, skinks, and dragon and monitor lizards. The lone crocodile that lives in the preserve is the estuarine crocodile, a saltwater species.
Frogs and Toads
Animals such as frogs that enjoy the lush foliage and wet environments abound in Bukit Timah. Notable species include the Malaysian horned frog and the red and white spotted tree frog. The frogs of the preserve live in the trees and water, and several toads that prefer burrowing or dry land also call the preserve home. Not all of the species are exotic. The common American bull frog also calls this lush Singaporean jungle home.
