been known to consume the larvae of Heliothis moths, a cotton plant pest, as well as mites. The knife-footed frog is adapted to living in environments where water availability is seasonal. To prevent desiccation, it burrows underground and forms a cocoon while undergoing aestivation, a period of dormancy. When threatened, the knife-footed frog utilises defence mechanisms to avoid harm. These consist of inflating the body then raising its rear slightly. If the threat continues, it elevates its entire body on all fours before rocking back and forth towards the source of the threat. The knife-footed frog emits a defensive call that is higher in pitch that of larger hylid species such as Cyclorana australis and Cyclorana novaehollandiae. Reproduction Breeding takes place opportunistically after heavy rains usually from September to April. After this heavy rain, males take up position on the edges of semi-permanent waterbodies and emit a call that is a high-pitched stead moan which ends in an upward inflection. The call lasts around 1 second and is repeated, with males answering each other in chorus. Calls from males occur one after the other, with a slight difference in pitch. Breeding events usually only last for one to two days. Like other species within the Hylidae family, the knife-footed frog breeds in pectoral amplexus, where the male grasps the female by the armpits from behind in order to fertilise her eggs. The spawn of the knife-footed frog has not been described but they are likely to be similar to other Cyclorana species with eggs being laid in large clumps floating or submerged in open water of creeks, ponds, drainage ditches and clay pans. The tadpoles of the knife-footed frog grow up to 65 mm in length. Eyes have golden irises and are situated at the sides of the head. Body colour is dull grey to light sandy gold to silver white with darker colour underneath the abdomen in clear or tannin-coloured waters. The entire body colour is pale gold or silver in muddy or opaque waters. Dorsal and ventral fins begin about a third of the way down the body and are mostly clear or milky in opacity. Tadpoles feed throughout the water column, voraciously consuming dead insects and other tadpoles. Where oxygen levels are low, knife-footed frog tadpoles can be seen taking air from the surface frequently and congregating in groups. Growth is rapid, like other Cyclorana species, with
