The giant banjo frog, giant pobblebonk frog, giant bullfrog, or great bullfrog (Limnodynastes interioris) is a species of frog, endemic to Australia, in the family Limnodynastidae. Fry was the first to recognise the species of Giant Banjo Frog (Limnodynastes interioris) as a distinct subspecies of Banjo Frog (Genus: Limnodynastes), differing from the similar Southern or Eastern Banjo Frogs (Limnodynastes dumerili) which occupied most of eastern Australia. Description The Giant Banjo frog grows to an average length of between 7–9 cm. The skin on its back is mostly brown with irregular black markings and a bumpy texture while its underside is pale to bright yellow and smooth. Along the sides of the body, the colouring ranges from red-brown to fawn with black and grey flecks with a black stripe from its snout down to its sides. The iris is a dark specked gold and the pupil is horizontal. Front feet are unwebbed and back feet are semi-webbed with a large, shovel-shaped metatarsal tubercle on the under-surface of each foot. The toes are strong, without discs and are predominantly for burrowing beneath the surface of soil. The eggs appear pigmented and are spawned within a large foam mass situated within flooded burrows and surrounded by vegetation. The tadpoles are quite large in comparison to other Banjo Frog species, growing up to 9.5 cm in length, and are dark brown, or black in colour with gold clusters and dark grey fins. Taxonomy Fry was the first to recognise the species of Giant Banjo Frog (Limnodynastes interioris) as a distinct subspecies of Banjo Frog (Genus: Limnodynastes), differing from the similar Southern or Eastern Banjo Frogs (Limnodynastes dumerili) which occupied most of eastern Australia (see Scientific classification for full taxonomy). Ecology Distribution The Giant Banjo Frog is endemic to Australia and inhabits the arid region of central New South Wales and northern Victoria. It is largely restricted to Murray-Darling Basin and the floodplains of the Murray River. The area of occurrence of the Giant Banjo Frog covers an area of approximately 214,800 km2 (see Distribution map). Population The Giant Banjo frog has a large and stable population with a conservation status of least concern. However, their habitat is threatened by habitat loss due to hydrological modifications of the Murray-Darling Basin which significantly disrupts inland floodplain frog communities. Despite a general negative impact of introduced species on inland frog communities, the presence of Common Carp (Cyprinus
