not predicted to be flooded, the clutches of large eggs result in the most success, whereas variable egg sizes are produced in the clutch when the parents cannot determine the condition of the offspring's environment. The tadpoles can adapt to specific conditions in the environment such as low water depth. The speed up in metamorphosis and larval period can result in reduced survival, decreased size, and decreased ability in jumping. Decreased size and jumping ability result in decreased fitness. Decreased jumping performance may lead to increased susceptibility to predators and decreased ability in catching prey. Additionally, decreased size influences male mating success and strategies, decreases ability to catch and consume prey, and decreased aerobic performance. For females, low water depth can increase maternal fitness as larger ova are produced however less ova are produced which can impact fitness as well. The mating, and thus the laying of eggs, occurs in seeps that are shallow and temporary and often dry up before tadpoles metamorphose (roughly 4–7 weeks). This results in unique adaptations, such as the development of Crinia Georgiana tadpoles in eggs that are very large relative to those of other species. This allows them to mature earlier and cope with unpredictable climates. Within the species, tadpoles with larger eggs are more likely to survive to the stage of metamorphosis. Females that lay smaller eggs also lay more of them; it is logical that since smaller eggs have a decreased chance of survival, a female would produce more to increase the chances of regenerating the species. Egg size and number of eggs laid varies unpredictably from female to female, so it is unclear why some lay large eggs while others lay small ones, but more of them. Tadpole survival It has been determined that although tadpoles with limited foodstuff (i.e., a smaller egg) have a higher rate of mortality, those that do survive can still complete metamorphosis at the same rate as those that have plentiful food. In addition, if water levels drop, tadpoles can speed up development so as not to remain in such a fragile state while water, a critical resource, is limited. This indicates that the quacking frog has developed adaptations that allow for its survival in the dry climate of Western Australia.
