This new Web site from the Center for C. elegans Anatomy is still under construction, but many site features are currently active. Although the Handbook of Worm Anatomy is not completed, there are some extremely detailed images that can be accessed through the Handbook link. The site is a repository for a variety of worm resources including abbreviations, scientific protocol, and a link to the Wormbase database of gene mapping and sequencing information. One feature that is under construction is a database of worm anatomy, which will likely add a great deal to the appeal of this site once it is completed.
