Pecten Palace
(Sponsored by Schooner Specimen Shells)
      Ultimately, this site aspires to be an " Online iconography" of the living Pectinidae and Propeamussiidae.   Of all the molluscs, the Pecten family is one of the most colorful and variable: many of its 300 or so species are extravagantly variable  in color, pattern and often sculpture - local populations of the more variable species such as  Aequipecten opercularis Linne, 1758.. and  Chlamys flexuosus Poli, 1795  often contain scores of distict variations, enabling one to assemble positively outrageous seres of specimens with no two being closely similar to each other.   If anyone out there in the wonderful world of Virtual Conchology wishes to contribute photos of species or forms not currently represented here, or exeptional images of any member of these two allied families, i would invite you to send them to me (Ross Mayhew) and i will promptly pop them onto the site - with proper credit of course! 
     Note:  Pectinidae taxonomy is notoriously "fluid":   almost any species at any time, is likely to have its genus changed, accordinging to a wide variety of schema new old and revised.    Therefore,  it naturally a bit difficult for a novice such as myself to keep up - and one is almost tempted to wonder what the point of doing so would be in any case.  That said, if you see any outdated generic assignments in the species represented thus far, please inform me and i will attempt to stay on top of things.
