There's no end to the danger of nature. The latest star on the scene is the Nile monitor lizard, a deadly, carnivorous monster that grows to 7 feet long. It likes alligator eggs, cats, and--reportedly--dachshunds. Native to Africa, like the pythons now battling for dominance with the alligators, they were let go by owners no longer able to deal with the beast. Said a biology professor from Tampa University, "One thing we do know: These are not little lizards eating bugs." Now, the little lizards we have hundreds of in the back yard (along with the possum family), but no carnivorous monsters, yet. The Everglades, however, is becoming a sort of Jurassic Park and, since most canals connect to it one way or another, it won't be long before they make an appearance in our own back yard. Look out, possums.
