Conchylinet v.2.9 - 2014-04-16
3203003 visits since Jan. 2007.
This tool has been built essentially to ease and accelerate the identification of a shell from the species recorded in the Conchylinet database.
It adds the shell general shapes to the filtering features of the specie plates
| Group | Shape | Description | Example |
|---|---|---|---|
| Univalve not coiled |  | Category 1 Univalve shell Shell not coiled | limpets |
| Univalve coiled |  | Category 2 Univalve shell Coiled shell Aperture small: aperture height lower than one third of the shell total height | screw shells |
 | Category 3 Univalve shell coiled shell Aperture medium: aperture height between one and two third of the shell total height | periwinkles | |
 | Category 4 Univalve shell coiled shell Aperture large: aperture height higher than two third of the total shell height | cones, cowries | |
| Bivalve |  | Category 5 Bivalve shell shell round to ovate fine to strong concentric sculptures | tellins, clams |
 | Category 6 Bivalve shell shell ovate to tapezoidal, solid fine to strong radial sculptures | cockles, scallops | |
 | Category 7 Bivalve shell shell elongated and light faint or no sculptures | mussels | |
 | Category 8 Bivalve shell shell of various forms raw or spiny sculptures | oysters, box shells | |
| Others |  | Category 9 other shell shape and shell-free mollusk | tusk shells, seaslugs |
When clicking on a main shape, the related sub-shapes will be displayed.
You have to choose and click one of these sub-shapes to filter the plates accordingly.
To deactivate the shape filtering, just click the RESET button on the right.
Note that if the shape you selected does not match any species already filtered by the specie filter, the result will be nothing!
Notes: the number of shapes has been limited to avoid too much complexity for the novice collector trying to identify his shells.
Moreover, the specie shapes have been set arbitrarily, you may not agree with some choices done to a specie.
Feel free to send comment about it and propose more relevant shapes drawings.
