No Way Out

Residents gaze in wonder at a 4.5-foot (1.4-meter) Nile monitor lizard captured near their homes in Cape Coral, Florida. Imported from Africa as pets, they can grow to more than seven feet (2.1 meters) long—way too big and feisty for the average owner to handle. "They're horrible pets," says Todd Campbell, the University of Tampa ecology professor who trapped this lizard. "They have a high propensity toward being aggressive and untameable." As a result many are released into the wild, where they breed and prey on native birds, small terrestrial mammals, and other reptiles.
