Desert Spadefoot Frog

Notaden nichollsi is typically found sand dunes due to the water potential properties around the Southern Kimberly region of Western Australia, Northern Territory and into western Queensland.

Notaden nichollsi undergo aestivation in burrows near the dune crests after rainfall during periods of water shortages. These burrows serve as shelters where the frogs can seek refuge during periods of extreme heat or dryness, as well as provide a safe environment for reproduction and the development of tadpoles. Notaden nichollsi, like other non-burrowing frogs, relies on mechanisms to maintain water balance. One key aspect is the regulation of the hormone arginine vasotocin, which acts as the primary antidiuretic hormone for most frogs.
