Family : RANIDAE
Species : Lithobates catesbeiana
Size (snout to vent) : 17 cm

A native of the U.S.A. and southern Canada, this species has been freed into ponds and reservoirs in Singapore as a means of religious merit-making. This is potentially damaging to the amphibian diversity of Singapore's Central Catchment Area, as this large frog may well out-compete local species. 

Its size may reach 15 cm (snout-to-vent), and the colour is usually greenish-brown, with a green head. In females the tympanum (external ear drum) is of equal size to the eye, and in males much larger. The hind feet are well webbed.

They feed on crustaceans, worms and insects and will also take other amphibians, including their own kind. They are bred for food, as their hind legs are muscular and well suited as 'frogs-legs' for the local restaurant market.
