Hee Hee! Cypraea turdus may have nothing to do with excrement, turds, or doo-doo - but Cypraea stercoraria actually does! The Latin noun stercus and the prefix stercor- refer to excrement, as does the english adjective stercoraceous. Apparently that's what Linnaeus thought this cowrie looked like! And Linnaeus was not one to hold back when he thought a species resembled something, be it a part of the human anatomy, or even a pile of dung. :-) Paul M.
