Physical description

Adult Marbled Frogs reach about 4.5 centimetres (1.8 in) in length, sometimes larger. Toes are long and unwebbed. Grey to light brown on back with numerous prominent darker blotches. The belly is white. Males have a yellowish throat and numerous small sharp black spines on their backs. When disturbed their skin excretes large amounts of mucous.

Ecology and behaviour

The Marbled Frog tends to be solitary inhabiting thick ground vegetation and is more often heard than seen. Males often call from hidden sites, usually partly submerged beneath vegetation. Its call has been described as "a rapid series of uk uk uks". Eggs are laid in a floating foam nest under vegetation and are small and brown. Tadpoles reach 7 centimetres (2.8 in) in length.

The Marbled Frog inhabits waterholes and pools in open grassland and woodland.
