In a report from The Week online, these African snails that found their way to the U.S. are capable of eating hundreds of plants, laying up to 1200 eggs, living up to 9 years, and EATING YOUR HOUSE!!!
I'm not kidding about the house thing. Stucco is a good source of calcium for their shells and they are perfectly capable of eating the stuff! And because of their size and hard shells, they can also puncture your car's tires if you run over one of them!
Here's a 30 second video that was created to inform movie goers.
So far they're only in Florida, and with the climate, that's most likely where they will stay. Environmental workers are catching around 1,000 of these slimy creatures every week, and hoping to stop the takeover of these snails.
