ID of shells found on east coast of UAE / Oman

[dave r]

Hi there, I am presuming these are all Red Sea specimens? I will give it my best shot!
#1 Bulla ampulla, Ampoule Bubble Shell
#2 Oliva bulbosa, Bulbous Olive
#3 Callista species, possibly C. multiradiata
#4 Paphia textile, Textile Venus
#5 Possibly a Circe species?
#6 Murex species, probably M.forskoehlii
#7 Looks like Polynices didyma, the Bladder Moon Snail
Just a word on photography to make identification easier, if you photograph both 'sides' of the shells (dorsal and apertural) it can make identification much easier as the aperture often holds the diagnostic features. Likewise the clams, sometimes the 'inside' of the shell can define which species it is. A lot of the bivalves are pretty much indistinguishable from the outside, you can't even get the family with out looking at the hinge teeth etc.
That is a nice selection of shells you have there, all in pristine condition. If you have any of those Olive shells or Murex to spare I would gladly swap them for something.
Cheers,
Dave
