There are about 110 species of

changeable lizard. The changeable lizard has pushed the local green crested lizard
into forested areas.

In gardens and parks, one can often see

common sun skinks, the introduced red-eared sliders
and flying lizards.

Water monitors are common in rivers and mangrove. Another monitor that can be found in Singapore is the clouded monitor, which is a forest species. It is smaller than the Malayan water monitor, has slit nostrils and is paler in colour. In 2008, the Dumeril's monitor was rediscovered in the Central Catchment Nature Reserve.[3]

Equatorial spitting cobras can still be found in desolated urban areas of Singapore. The bigger king cobra is much rarer. The banded krait sometimes show up as road kills. There are also 2 coral snake and 9 sea snake species.
