Another freebee

Every once in a while you hear on the news that some undiscovered species has been found some where in the world that excites the scientific community. If you like that type of adventure, buy a saltwater aquarium. If you have the patients to sit and stare at a tank, you'll find yourself eventually saying "oh my God, what the heck is that!" This guy is really hard to see but I'm guessing it's some sort of limpet. It has a pseudo shell and it's has a body and antennae like a snail, and I assure you, I got it for free somewhere.
