Reptiles are ectotherms that require precise temperature gradients for thermoregulation, digestion, and immune function — needs frequently unmet in captivity.
The pet reptile trade involves enormous mortality at every stage from wild capture to importation to captive keeping. Even well-intentioned keepers often underestimate the complex needs of reptiles. Providing appropriate thermal gradients, UV lighting, humidity, and diet are essential for reptile welfare and often require significant investment.
