Trilling Frog
Background
The Trilling Frog is easily confused with other burrowing frogs. This is not surprising as many of the Neobatrachus species look very similar. The Trilling Frog is characterised by a high and broad head. Its colour is mostly sandy-grey to brown with irregular dark and light markings. The frog may also have a stripe running down its back. The eyes are large and the tympanum (ear) is not visible. The limbs are short, the toes are cylindrical and extensively webbed while the fingers have no webbing.
