underwater butterflies

it strikes me that these may be the prettiest clam shells i have ever seen. now, i didn’t grow up by an ocean. so you guys, collectively, will have to tell me whether i am right or wrong.  do clamshells get prettier than this? we can have that argument whenever you’d like. whether clams get tastier than mediterranean palourdes, however . . . there you have a lot more convincing to do.
