Australian Red-claw Crayfish (Cherax quadricarinatus)
Tampines Quarry Lake, 10th September 2012

This exoskeleton of an Australian Red-claw Crayfish was found on the shore of Tampines Quarry Lake, an artificial lake that formed out of a disused sand quarry. Hence most of the larger aquatic fauna like fishes and decapod crustaceans are likely to have been introduced by humans. The presence of a crayfish exoskeleton suggests that there might be a population living in the lake, although I have yet to see a living specimen.
