Zoo Komodo Dragons: Biology, Captive Requirements and Conservation Value

Komodo dragons are the world's largest lizards and require specialised captive environments. Meeting their thermal, spatial and dietary needs is essential for welfare.

Key Facts

Komodo dragons can reach 3 metres in length and weigh up to 70 kg.
They are ectotherms requiring precise thermal gradients ranging from 30 to 40 degrees Celsius.
In the wild they roam large territories and may travel several kilometres per day.
Their diet consists of large prey items including deer and pigs, consumed in infrequent large meals.
Captive Komodos often develop obesity due to overfeeding and insufficient exercise opportunity.
The IUCN lists them as Endangered following recent reassessment due to climate and habitat threats.

Welfare Considerations

Komodo dragon welfare in captivity centres on thermal management, space adequacy and appropriate feeding regimes. Inadequate basking temperatures impair digestion and immune function. Small enclosures prevent natural ranging behaviour and contribute to stereotypies and obesity. Best practice involves large naturalistic enclosures with varied substrate, multiple basking spots at different temperatures, infrequent large prey items rather than frequent small meals, and environmental complexity including climbing and burrowing opportunities. Conservation value is maximised through coordinated international breeding programmes.
