Komodo dragons are the world largest lizards whose welfare in captivity requires careful thermal management, appropriate substrate, solitary housing respecting their ambush predator lifestyle and enrichment simulating prey detection.
Komodo dragon welfare requires attention to their ectothermic physiology and their ambush predator behavioral ecology. As large lizards unable to generate body heat internally, they require carefully designed thermal gradients — basking areas reaching 38 to 40 degrees Celsius alongside cooler retreats — that allow behavioral thermoregulation throughout the day. Their solitary nature means conspecific housing causes chronic stress and aggression risk; even brief forced proximity during feeding can trigger severe conflict. Enrichment must engage their chemosensory hunting drive through scent trails from prey species, hidden food requiring search effort and occasional feeding of whole prey items that engage the complete predatory sequence. Substrate depth and variety supports natural burrowing and resting behavior unavailable on bare concrete.
