American Bullfrog (Rana (Aquarana) catesbeiana)
Tampines Quarry, 11th September 2016
Two juvenile American Bullfrogs were found along the shore of the lake in Tampines Quarry. They were alive when first spotted, but had died by the time they were seen again an hour later. The other individual was featured in an earlier instalment of Daily Decay.
Young, newly metamorphosed American Bullfrogs are widely sold in aquarium shops in Singapore as live food for large predatory fishes, although it's possible that these juveniles are also purchased to be used as bait for anglers, or are deliberately released by well-meaning people who do not understand the ecological harm that can result from releasing potentially invasive species.
