The Growling Grass Frog is one of Australia’s largest frog species, with females reaching up to 100mm in size. In the past, these frogs inhabited a large area of south east Australia, however their range and population is in decline. They are still present in Victoria but are classified as endangered. ESSA is currently positioned just north of Ballarat where this species has become very scarce. They are generally olive to bright green in colour with spotting across their back. They have small teeth which are used for holding their prey prior to swallowing. Prey usually consists of lizards, snakes ad small fish. This species live in vegetation at the edges of still or slow flowing water where they take cover while waiting for their prey.
