there are several other species we have found, we were lucky , when my wife
and i 1st moved to S. FL they had just replenised the beach at hallandale,
we spent weeks in the surfline with stainers , we plunged the strainers into
the marl where the waves crashed then washed out the sand , in almost every
scoop there would be something new. i didn't mention many species as frankly
i've forgot them all. thanks for your time , mark and peta bethke
