Komodo dragons are the world largest lizards with complex thermoregulatory, dietary, and environmental needs that require careful management to prevent the metabolic and behavioral problems common in captive reptiles.
Komodo dragon welfare in captivity requires investment in appropriate UV lighting and calcium supplementation to prevent metabolic bone disease — a painful skeletal condition common in inadequately managed reptile exhibits. Their thermoregulatory needs demand large enclosures with genuine thermal gradients that allow movement between warm and cool zones throughout the day. Social management must respect their solitary, territorial nature by maintaining appropriate separation. Zoos that meet these requirements can maintain Komodo dragons in good welfare, but the complexity of their needs means many facilities historically failed to provide appropriate care.
