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.

Any idea what species this is? Spotted at Sengkang Riverside Park.

This is an American Bullfrog (Lithobates catesbeianus), presumably released by people.

Kranji, 27th June 2011

This medium-sized frog was found on the KTM railway tracks that run through Kranji.

Based on the size and the patterns on the skin that remains on the legs, I suspect that it might be a subadult American Bullfrog (Lithobates catesbeianus).

Another possible alternative is that this was a large Crab-eating Frog (Fejervarya cancrivora).

Neo Tiew Road, 20th December 2008

When I first encountered this bullfrog, it was still very much alive, and sitting by the road just outside Khai Seng Trading & Fish Farm. No prizes for guessing where it had just escaped from.

After some time, the bullfrog attempted to cross the road, and after a few near misses, it was finally struck by a passing car. A horrible end, even for an unwelcome, potentially invasive species.
