Freshwater Molluscan Shells / site information


The germ for this site was planted in the early 1990's, when I found there was no general book on freshwater mollusks.   I knew if anyone was aware of one, or future potential for its existance, it would be Dr. R. Tucker Abbott (now deceased), the well-known authority and popularizer of malacology.   After a few calls to directory assistance, I was in touch, and asked him if he knew of anything in the works.  He told me "no" but that it sounded like a worthwhile project, and that maybe I should do it.   I said I'd think about it, but didn't feel it was too realistic -- I lacked connections, means, and the will to engage in travel to collections that might be in other parts of the world.   To satisfy my curiosity, I acquired a few non-local freshwater specimens from mail-order dealers.   The web was growing rapidly and there were several early items about freshwater mussels.   In 1999 a friend was building a site to sell mineral specimens, and I realized it could be done by anyone, so why not me.  I bought a scanner and liked the results immediately.  

Since the first few pages, I have tried to incorporate new pictures and information as I can.   There are no ambitions toward making the site comprehensive. The goal is to create an overview stressing the variety of freshwater species and their relationships, to include the more common, important, widespread or interesting ones, and hopefully to allow a user to identify specimens to family level anywhere in the world.

Site structure: Prior to October, 2008, the site spanned several subdomains under "members.aol.com." AOL permitted several per account, each with a 2 megabyte online storage allotment without advertisements. "Mkohl1,""mkohl2," "savetheclams," etc. were subdomains created under this system. At that time the site was copied and uploaded to the servers maintained by 1and1.com. Copying from the online version using Internet Explorer simplified the image directory structure and made far fewer alterations necessary.

Site usage: This site is frequently used by students researching homework assignments.  Weekends, and the summer and winter school breaks in North America are reflected by lows in the statistics, accessable [here], or through the link at the bottom of the home page.  Many of the searches below also suggest this use.

"How do fresh water snails change shells" and other searches: The statistics also indicate search arguments or "strings" entered into search engines that returned the site URL.  The compilation below was initiated soon after the site was inaugerated January 1, 2000.  Almost all are included but for some variations in capitalization and plurals (first usage recorded).  Some are informative, for instance "tbt imposex" is a very real environmental problem caused by tributyl tin anti-fouling compounds. Note the number of searches for photos, images and diagrams.  People want to see it.  Clearly, some found what they wanted here.  Others may have found it only through the links, if at all.  Many were looking for information beyond or outside the scope of this site.  In some cases, for example, care and cleaning of specimens, and anatomical diagrams, they suggest additional pages are needed.

By the way, they don't.
