15. Adaptations to Drought: Estivation
To survive prolonged dry spells, some amphibians undergo estivation, entering a dormant state where their metabolic rate drops dramatically. Cutaneous respiration is reduced to minimize water loss, helping them endure arid conditions. Species like the African bullfrog burrow into mud and remain inactive until moisture returns. This remarkable adaptation highlights the resilience and flexibility of amphibian respiratory systems in the face of environmental extremes. Learn more
