3 shells I need identified
I recently went on a marine biology trip and for our homework we need to make scrapbook pages, and one of my pages i have to identify three shells i found in the Bahamas.  They were all found in the Exhumas in the Bahamas.  I have two gastropods and one bivalve.  The pictures arent so great which will make precise identificiation tough, but really all i need is a rough identification.  I would really appreciate any help with these.  I havent been able to find anything on the internet to help me identify them.

Univalve

3 shells I need identified
Hello,

Your first shell is Strombus costatus, the so-called "milk conch".

The bivalve appears to be Laevicardium laevigatum, the "common egg cockle".

The third shell appears to be a Cerithium, but I can't see enough detail to be certain of the species. Cerithium eburneum, the "ivory cerith", would be my best guess, though it doesn't look quite right to me. How large is the shell?  Cerithium eburneum usually doesn't excede 30 mm in length. If this is a bigger shell, I'd be interested in knowing - and possibly in a better picture?
