Family Myobatrachidae, Genus Limnodynastes
The name Limnodynastes literally means "Lord of the Marsh". All spawn in water, constructing white foamy floating rafts which contain the eggs. All are solidly-built and powerful jumpers and swimmers.
The genus is represented in Victoria by five species, ranging from the 40mm-long Spotted Marsh Frog to the Great Bullfrog at up to 100mm. A number of lifestyles are exhibited ranging from burrowers in semi-arid zones to almost fully aquatic.
The Victorian members of this genus are characterised by having a horizontal pupil, an indistinct or hidden tympanum (ear), smooth belly and usually at least vestigial webbing on the toes.
