Description
The Striped Burrowing Frog or Cyclorana alboguttata is a species of Burrowing Frog known for its ability to bury itself in the mud for years without access to food or water. This ability is due to the heightened function of its Mitochondria, giving researchers hope for vital information regarding energy-dependent diseases such as Obesity and Mitochondrial Disease[1]
The Striped Burrowing Frog ranges in color with its dorsal ranging from olive, green or brown accompanied by darker markings. There are 1 to 3 pale yellow to yellow-green stripes down the middle of its back and along its sides. There is a black stripe from the base of its snout to its rear running across both eyes. The thighs range from light to dark brown to black with white spots and some brown specks along its chest and throat, both of which are white. Adult females grow to 85 mm in length and adult males grow to 70mm long. [3]
Habitat
The species is found along the East coast of Australia spanning from Sydney into the Northern Territory. [2] They can be found in woodlands and grassy regions around temporary pools or other sources of water. While they prefer ample rainfall and access to water, they are often found in dry or arid regions due to their ability to bury themselves in mud and enter a state of torpor while buried in the soil, further discussed under the 'Behavior' section.

Burrowing
Burrowing Frogs are known for their ability to bury themselves in moist soil during conditions of ample rainfall and remain there for extended periods of time without harm while the soil around them dries, only to emerge again when the conditions are wet enough. They use their back legs to dig a whole in the soil where they will remain from months to years at a time. They can store up to 50% of their body weight in water in their bladders. This will supply them with moisture while they are underground. Before they begin their state of torpor they release a shield of dead skin cells to act as a barrier to limit water loss.[4] During the state of torpor, their body does not require food because it decreases its metabolism, allowing the frog to maximize its energy supply without completely depleting its resources. [5]
Reproduction The species breeds during spring and summer peaking in the months of January and February. Males call to females up to 3 months before breeding season and don't stop until 1 month after peak mating season. Females lay eggs along the edges of bodies of water and the male attaches themself to the back of the female and fertilizes the eggs externally after the female lays them. [6]
