21. Spadefoot Toad
Spadefoot toads are remarkable amphibians known for their ability to survive prolonged periods of drought through a behavior called estivation. During these dry spells, they burrow deep into the soil, significantly reducing their metabolic rate to conserve energy and water. This dormancy can last for several months, with some species remaining underground for up to nine months. (kenstoreylab.com)
When rainfall occurs, spadefoot toads emerge to breed in temporary pools formed by the water. Their rapid development allows them to complete their life cycle before these ephemeral habitats dry up. (myodfw.com)
These adaptations enable spadefoot toads to thrive in environments where other amphibians might not survive, showcasing their resilience and specialized survival strategies. For more information, see Smithsonian National Zoo.
