How long does the tadpole stage last for most frog species?

For most species of frogs and toads, the tadpole stage typically lasts from one to three months.12

While this is the general duration, the length of the larval stage can vary significantly based on environmental conditions and species-specific adaptations. For example, some species, such as the spadefoot toad, may complete their development in as little as two weeks to survive in temporary pools. Conversely, other species, such as the bullfrog in northern regions, may require up to three years to undergo metamorphosis.21
