The ability of conservation biologists to ascertain the extinction risk of a species to these threats requires data o n changes in distribution\, abundance\, life history\, and ecology. The Int ernational Union for the Conservation of Nature (IUCN) uses these data to a ppraise the threat status for a species. However\, many species remain data deficient (DD) or unassessed. Here\, I use 14 morphological traits related to locomotor function\, habitat\, and feeding to predict the threat status of over 400 species of lizards in the infraorder Iguania. I used an artifi cial neural network (ANN) approach to generate a classification function ba sed on the morphological traits of species with an assigned IUCN threat sta tus. The network approach identified a model with a classification accuracy of 87.4%. Moreover\, the ANN model predicted >18% of DD/not assessed speci es were at risk of extinction. The predicted assessments were supported by other sources of threat status\, for example\, Convention on International Trade in Endangered Species appendices. Because of the functional link betw een morphology\, performance\, and ecology\, an ecomorphological approach m ay be a useful tool for rapid assessment of DD or poorly known species.
