Abstract: | Summary Flagellated protists produce a diverse range of siliceous structures, such as internal and external skeletons, scales, spines, bristles, cell walls, cyst walls, and loricae. The different groups of silica-depositing flagellates, i.e., chrysophytes/synurophytes, choanoflagellates, dinoflagellates, ebriids, silicoflagellates, thaumatomastigids, and the genusPetasaria are reviewed. Brief mention is also given to those algal groups in which silicification is uncommon and rare (i.e., chlorophytes, euglenophytes, haptophytes/prymnesiophytes, xanthophytes/tribophytes), but in which silicified structures nevertheless occur in few flagellate genera. Special attention is given to aspects of morphology and development of the different siliceous structures as well as on aspects of systematics and taxonomy. |
