Over the summer we acquired a fish tank, and a co-worker of the Man had given us some snails. He had too many, and they're good for keeping the tank clean, so we were happy to take them. To me they were just brown snails, and other than the fact that they did keep reproducing and filling the tank with more tiny brown snails, I took little notice of them.
The United States Department of Agriculture however, is mighty interested in them. Yesterday morning the Man got a call from said co-worker, informing us that these snails, that he had originally bought on eBay, were now being confiscated by the government. They are some sort of ramshorn snail, and for some reason we aren't allowed to keep them. The Man bagged them up last night to go turn them over. The only info I've found seems to be that the USDA has issues with controlling their population in commercial fish ponds, though I'm not at all clear what that has to do with us.
The irony of having to turn over aquarium snails to the government isn't lost on me. Of all the illegal things I did in my previous life, possession of contraband slugs sure never made the list.
