The Crab-eating Frog is thought to be the most salt tolerant amphibians in the entire world. They are able to survive in brackish waters for extended periods of time and briefly survive swimming in salt water. With this species talent, they are able to feast upon crabs and other small crustaceans, hence their name. They are found along the shorelines, mangrove forests, and inland wetlands.
Reproduction for the frogs is pretty standard. They can breed year round but most activity is at the start of the wet season. At the start, the males will call for the females from a water body. Once the female arrives, the male will grasp her from behind in the amplexus positiion. Then, female will lay her eggs and the male will then fertilize them. Neither parent will provide any parental care for the offspring. The eggs will hatch into tadpoles that transform later into frogs.
The Crab-Eating Frog is listed by the International Union for the Conservation of Nature (IUCN) Red List as Least Concern of becoming Extinct. The frog has a wide range and is plentiful throughout it. They especially thrive in rice paddy fields. Potential threats to the survive of the frogs is the habitat destruction and over harvesting the frogs for food.
