There are about 110 species of reptiles in Singapore. Most of them are small or rarely seen. But there are a few which are large or prominent. The largest reptiles which can be found in Singapore are the estuarine crocodile and the reticulated python. The ones most commonly seen in urban areas are the house geckos (typically called house lizard by the lay-person) and the non-native 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.
