 The green iguana is present as an invasive species on some of the islands of Fiji, where it is known as the American iguana.They pose a threat to the native iguanas through the potential spread of disease and to humans by spreading salmonella.They were initially brought to Qamea in 2000 by an American who wanted them to eat the numerous insects on the island, although they are primarily vegetarian.They are now on the islands of Laucala, Matagi and Taveuni.
