I have a bunch of animal parts... mostly aquatic, and most of which I found myself. Today my parents gave me some awesome ocean artifacts they bought... a Fire Oyster shell, a Channeled Whelk shell, a Chambered Nautilus shell, and a Tiger Shark tooth inside a keychain. And it got me thinking... where do they come from? I'm hoping they were found empty on a seashore or on the ocean floor because I hate animals being killed for souveneirs. So what's the verdict?
