This site showcases my collection of New Zealand marine land and freshwater shells, of greater than ~10mm size.
These are mainly Mollusc shells, but Brachiopods, Barnacles, Urchins, and Tubeworms are also represented.
Basic information for each species is provided, and I endeavour to keep the species names up to date with the latest taxonomic developments.
The Image Pages contain thumbnails of over 1100 shell species and forms. Click on a thumbnail to see the specimen image, which includes the locality data for that specimen as well as its size. Some basic metrics such as geographical range, habitat, and maximum size are included with each species thumbnail.
The Species Page gives access to all the images via a text list. This is more bandwidth friendly than thumbnails.
The Filter Page lets you filter most of the shells by various criteria. Its purpose is to assist with shell identification.
On all pages, the search facility (Ctrl-F) can be used to locate a family, genus, or species by name.
