If you are a Mac computer user, you can view Slidable worm with the internet browsers; Netscape communicator 6.2 or Internet Explorer .

The preliminary table of SW images has been moved to here. Please note, however, this table will not be updated from now on and new images will only be added to the applet. It is also highly recommended that you read the directions about how to use the applet before viewing the Slidable Worm.

    01/03/2002:

  • This atlas concentrates first on features of the adult anatomy of the hermaphrodite nematode, followed by a concise description of key differences in the adult male anatomy. At a later date, we will also try to provide comprehensive coverage of the anatomy of the L1 larva, and where feasible, some features of embryonic development. All features are described from the species Caenorhabditis elegans, and concentrate on the wild type. In the future we look forward to illustrating key mutant phenotypes of this species, using a similar format. It remains difficult to provide extensive illustrations of these tissues within the scientific literature in journal articles, and we expect that this type of enhanced database should prove useful to many studies.This atlas is aimed to make nematode anatomy relatively simple and accessible to everyone. We welcome your inputs, comments, and submissions. Any submitted data will appear in WA with proper academic credit given to the original submitter.
  • It is highly recommended that the user guide is read before going through the other pages in this atlas, since the user guide will help you utilize the data herein optimally.
  • Wormatlas is being prepared in close collaboration with the Wormbase; throughout WA you will find links to relevant WB pages.
