· Chitons (Polyplacophora)
· Tusk Shells (Scaphopods)
· Cephalopods (Nautilus)
· Aplachophora & Monoplacophora

· Land Shells

To take full advantage of the Web site's functionality your screen resolution should ideally be set at 800 X 600 or greater. Screen resolutions set at 640 X 480 will suffer from the annoying horizontal scroll bar. is a graphics-intensive site, so it may take a bit longer for pages to load if your modem connection is slower than 56k. Many of the images and pages open in separate pop-up windows. If your browser has a plug-in that prevents automatic window popups, you will have to turn this function off to see the enlarged shell images. does not employ any automatic advertising window popups anywhere on this site. You will not be fighting advertisements that seem to spawn multiple windows when closed. So turning off your popup window prevention software will not affect your browsing experience on this site.

Clicking on the shell image thumbnails will open an enlarged image in a separate resizeable window with an auto-close feature. This means that you can close the window by clicking on the background of the page below the window, as well as by clicking the "Close Window" link below the image at the bottom of the window. You can also use the standard browser functions to close the window. Each new opened image window will replace the previous window. Only one window can be opened at one time. This prevents an accumulation of opened pages which can slow the performance of your computer.

The multimedia slide presentations will load relatively quickly during off-peak hours using a 56k modem. No matter how fast the processing speed of your computer, it will take much longer to load the images if there is a lot of simultaneous traffic on a slide presentation. The larger programs of 15 or more slides may take as long as 4 to 5 minutes to load during peak periods. You can monitor the loading status from the status bar at the bottom of the slide show window. You do not have to wait until the entire slide presentation loads to start viewing the program. The slides are viewable as each one loads up. Just click on the NEXT button to advance through the slides.
