Komodo dragons are apex predators with specialised environmental needs that present significant challenges for welfare in zoological collections.
Komodo dragon welfare in captivity involves meeting requirements quite different from those of mammalian zoo species. As ectotherms, temperature regulation is not merely about comfort but about physiological function — digestion, immune response, activity levels, and healing all depend on access to appropriate thermal gradients. UVB light is essential for vitamin D synthesis and calcium metabolism; deficiency causes metabolic bone disease, a painful condition causing progressive skeletal deformation. The difficulty of veterinary examination due to venomous bite risk means that welfare problems can go undetected until advanced. Zoos with well-designed Komodo dragon exhibits — providing large basking areas, temperature gradients, hiding zones, and appropriate diet — demonstrate that good welfare is achievable with investment in appropriate infrastructure.
