You may be asking yourself: "What exactly is a worm atlas?" It is a fair question, and the answer is that a worm atlas is a database of the behavioral and structural anatomy of Caenorhabditis elegans, or a transparent roundworm. The website was created in conjunction with the Albert Einstein College of Medicine at Yeshiva University. Nematode neophytes may wish to read over the "What is C.elegans?" area and then continue their journey through the site. The "Handbook" area contains slides of the various roundworm types (such as male and embryos), complete with detailed images of their various body systems, such as alimentary, excretory, and muscle. Moving along, the "Resources" area includes the "Slidable Worm", which allows visitors to view slides that document the sections of the roundworm. Also, visitors can look over a glossary of terms, information about cell lineages, and short videos. The site also contains a "Worm Literature" area, which features key published studies on the structural and developmental anatomy of C. elegans.
