The Green Crested Lizard (Bronchocela cristatella) is a lizard found in South East Asia.
It is bright green in colour, sometimes with a bluish tint in the head area. When threatened, it can turn brownish in colour. The male has a neck crest. It has a very long tail that makes up over 75 percent of its total length.
In Singapore, it is in decline due to competition with the introduced Changeable Lizard (Calotes versicolor).
This picture was taken at the mangroves of Sungei Buloh in August 2012. The tail was a bit too long to fit nicely in the composition.
