You don't belong here

The other day I was watching Animal Planet and this show, can't remember the name of it, came on about these three guys that go out and catch reptiles that are not suppose to be where they are. About ten minuets into the show I realized that they were in Florida, not too far from Fort Myers. There was this one lizard they were trying to catch that was hard to find and lived in trees. The one the caught had this plastic tube thing around its neck. They ended up not being able to find a place for it to live so they had to kill it. One of the guys took the lizard back to its house to study it. He cut it open and looked in the stomach to see it had been eating. He found some bugs and other random half digested things. He then opened up one that did not had something restricting its air way and found ten alligator eggs. That was the problem with these lizards, they were not native to Florida and are depleting the population of those animals that are native. That was the job of the three guys.
