remember the cane toad, the rabbits, foxes, goats, pigs, horses, camels etc etc. They were brought over and now look at them. Whay happens when people bring over exotic species for their own ammusement, get sick of them and dump them?
Not to mention cats and dogs. Although If you want to bring in a dog or cat from overseas it has to be quarantined for six months, registered and microchipped. Im sure if you went to all that trouble and expense you wouldnt just dump it, you would be bringing it in cos you really wanted it. If exotics were allowed under the same system and have to be registered and microchipped, it could work.
I heard the snakehandler who found it, owns the alligator.
