On a recent shelling trip to South Padre Island we found several hundred
Angel Wing valves (Cyrtopleura costata Linne, 1758) on the beach.
Surprisingly, almost all of them (90-95%) were the left valve. I seem to
recall reading an article or study which was conducted on this type of
phenomenon but of course cannot remember where I saw it. Can anyone out
there in Conch-land point me to the article or better yet have an
explanation.
Thanks,
