Zoo Reptile Thermoregulation and UV Welfare

Reptile welfare is fundamentally tied to thermal gradients and UV-B light provision. Inadequate thermoregulation opportunity causes immunosuppression, metabolic bone disease and chronic stress.

Key Facts

Reptiles require thermal gradients to regulate body temperature behaviourally
UV-B light is essential for Vitamin D synthesis and calcium metabolism in most reptiles
Inadequate UV-B causes metabolic bone disease - a widespread welfare problem in captive reptiles
Appropriate hide provision allows thermoregulation and security simultaneously

Welfare Considerations

Reptile welfare requires thermal gradients spanning preferred active temperature to cooler retreat zones, appropriate UV-B lighting matched to species requirements, and hide provision. Welfare assessment of reptile exhibits should include temperature verification, not just visual inspection.

What You Can Do

Ask zoos about their reptile UV-B lighting schedules and thermal gradient provision
