Please help me identify these shells I found in Marco Island, Florida. The grey and white shell is about 1cm across. In the second attachment, I am trying to identify the two bivalves at the bottom of the photo on the left and right of the spiny jewel box.
Hi,
for me a little bit difficult to tell...... . Should be family Turbinidae, I think, Genus Astraea. Might be near to Astraea tecta. There are some subspecies with the spines/ribs sometimes more expressed, sometimes less. But it's just a guess...... :-\.
Kind regards: wolf
I would love to help but I can't see any photos, sorry.
