Amphibians such as frogs and toads are cold-blooded animals that metamorphose from a juvenile water-breathing form, to an adult air-breathing form. Amphibians are superficially similar to reptiles. Reptiles such as snakes, lizards, crocodiles are air-breathing whose skin is usually covered in scales.

Amphibian (5) - Malayan Giant Frog (Limnonectes blythii)
This is a juvenile Malayan Giant Frog, about 4 cm in length. An adult frog would not have the mottled botches on its whole body except the young. Adult looks quite different from young as it appears dull light green skin without mott. It could grow into a 17.5 cm giant frog!

Reptile (6) - Many-lined Sun Skink
Reptile (5) - Changeable Lizard
This widespread Asian native can easily be found in parks and gardens. Its colour ranges from brownish-buff to greyish, and in the breeding season the throat of the male becomes red and black.

Reptile (4) - Green Crested Lizard (GCL)
The GCL, in my opinion, is the most photogenic lizard in Singapore. The body colour is bright green, sometimes with a bluish tinge on the head. Its range is in decline possibly due to competition from the more common Changeable Lizard (Calcotes Versicolor). I was lucky to have seen them on a few occasions mostly at Venus Drive (5 times), Pulau Ubin and recently at Margaret Drive.

When threatened, its body can turn into brown colour as seen in the image below:

They are usually very skittish to human but on a lucky day, they may allow you to get some close-up shots.
Reptile (3) - Elegant Bronzeback (Dendrelaphis Formosus)
A common forest snake. Similar to OWS, its body is long and extremely slender. It has large eye which is at least half the diameter of the thinkness of the head. I have seen it at Venus Drive, Bukit Timah Bicycle Trail and Wild Wild West at end corporation road.

Reptile (2) - Malaysian Brown Snake (Xenelaphis Hexagonotus)
Reptile (1) - Oriental Whip Snake (Ahaetulla Prasina)
The OWS has a long and slender body which feed on lizards and small birds. It is inoffensive and only mildly venomous. A very photogenic snake. I have seen it at Segar Road bushes, Singapore Botanical Gardens, some bushes near Ngee Ann Polytechnic bus-stop, Macritechi Reservior Trail and the most recent one at Margaret Drive macro site.

Amphibian (2) - American Bull Frog (Rana Catesbeiana)
The American Bull Frog is a native of the U.S. and southern Canada. This species has been freed into ponds and reserviors in Singapore. It is the largest frog species in Singapore. This was spotted at a pond in Ang Mo Kio West Town Garden. My first encounter with such a huge frog, about 5 inches long. It was reported that there has been a noticable increse in the no. of this species in our reserviors. It can also be found in Singapore Botanical Gardens.
The male has ear drum bigger than the size of its eyes while the female is about the same size of its eyes. They are fred for food as their hind legs are muscular and well suited as 'frog-legs' for the local restaurant market.
