Amphibians face the most severe extinction crisis of any vertebrate group, making zoo husbandry and captive assurance populations critically important, but their specific welfare needs require specialized knowledge often absent from general zoological collections.
Amphibian welfare in captivity depends critically on environmental precision. Unlike mammals, amphibians cannot regulate body temperature behaviorally without appropriate temperature gradients - enclosures without thermal gradients prevent normal physiological function. Humidity management affects skin health directly - amphibians breathe and absorb water through their skin. Metabolic bone disease from inadequate UV lighting and calcium supplementation causes skeletal deformities and pain. The welfare and conservation functions of amphibian keeping are closely aligned - well-managed captive populations that breed successfully provide both conservation insurance and evidence that welfare needs are being met.
