Life History, Abundance, Activity, and Special Behaviors
Little is known about the biology of this species, however it is likely to be similar to that of L. aurea (Gillespie et al. 1995). Males call from Aug. to Apr. (Hero et al. 1991). The species breeds in permanent ponds or swamps, usually with extensive areas of sedges and rushes from which adults call (Gillespie et al. 1995). About 1698 eggs are laid in a loose clump (Hero et al. 1991, Hero & Warrell unpublished). Tadpoles are free swimming and develop over summer and autumn (Gillespie et al. 1995). Metamorphosis takes place between late summer and autumn, although tadpoles may overwinter and metamorphose the following season (Gillespie et al. 1995). Feeding
Adults are opportunistic predators, preying on other frogs and are also known to be cannibalistic (Hero et al. 1991; Gillespie et al. 1995).Invasive species
Litoria raniformis is usually found in association with dams, ponds and marshes, either amongst sedges and other semi-aquatic vegetation, or sheltering under logs and rocks (Gillespie et al. 1995). The species appears to be associated with permanent waterbodies though it is unclear whether, like L. aurea, the species also utilises ephemeral pools (Mahony 1999). The species occurs both in woodland and areas of improved pasture (Gillespie et al. 1995).
