| • | Acetabularia are giant (0.5 to 10cm long) unicellular and uninucleate marine green algae, with a characteristic umbrella-like shape. They are most famous from the experiments of Joachim Hammerling in 1953, where by transplanting parts of A. mediterranea and A. crenulata he showed that the genetic information of eukaryotes is contained in the nucleus. Species such as A. acetabulum are still used as model organisms for research on nucleus/cytoplasm relationships, cytoskeletal organisation and circadian rhythms.
There are about 30 species of Acetabularia (see: http://www.algaebase.org/), including:
