Komodo dragons are the world's largest lizards — apex predators with complex thermoregulatory and spatial needs. Keeping them in captivity requires precise management of temperature, space, and isolation to avoid stress and aggression.
Komodo dragons in zoos face welfare challenges arising from their size, thermoregulatory complexity, and solitary nature. Enclosures that are too small prevent natural locomotion and foraging exploration, leading to repetitive pacing and abnormal behaviour. Insufficient thermal gradients prevent proper digestion and immune function. Housing multiple animals together — sometimes done for visitor interest — generates continuous stress and dominance conflict. Best-practice facilities provide large enclosures with multiple thermal zones, deep substrate for digging, and strict single-animal management. Feeding whole prey items and providing olfactory enrichment (scent trails, novel objects) helps sustain appropriate behavioural engagement.
