Tim Jessop, from the San Diego Zoo, started the first demographic study on the Komodo Dragon population living on the four islands of Komodo National Park. The biggest individuals Ė males mostly Ė are lassoed by the team. Carefully avoiding the powerful tail the workers tape the animalís claws and the mouth to avoid their deadly bite. The animals are fitted with an electronic chip, an identification card stuck under their thick hind leg skin. Then they are weighed and measured to track precise documentation of the population dynamics. After four years in the field Jessop estimates the total population up to 3,500 individuals.
