It only enters the water for breeding when nocturnal temperatures are at their yearly maximums and within 2–3 days of rain. [6] The tadpoles hatch from eggs after 2 days and metamorphose within 2 weeks. Froglets hide in cracks and shade and live off stored tissue in their tails until they can start feeding as adults.
They can grow up to 2 inches in length. They can be found in the areas with sand or gravel in soils near temporary bodies of water.

If the water temperature rises above 32 °C (90 °F), developmental abnormalities occur, and if it falls below 15 °C (59 °F), normal development ceases. [18] Newly hatched tadpoles show a preference for living in shallow water on fine gravel bottoms. American bullfrog tadpoles have also "showed a preference for habitats containing structure."
