Abstract
Modifications to the mitochondria and flagellum of the Ophryotrocha spermatozoon render it immotile. The sperm may represent an evolutionary unstable intermediate between flagellate and aflagellate sperm types.
期刊介绍：
The European Journal of Cell Biology, a journal of experimental cell investigation, publishes reviews, original articles and short communications on the structure, function and macromolecular organization of cells and cell components. Contributions focusing on cellular dynamics, motility and differentiation, particularly if related to cellular biochemistry, molecular biology, immunology, neurobiology, and developmental biology are encouraged. Manuscripts describing significant technical advances are also welcome. In addition, papers dealing with biomedical issues of general interest to cell biologists will be published. Contributions addressing cell biological problems in prokaryotes and plants are also welcome.
