Acantharea - Wikipedia
The Acantharea are a small group of radiolarian protozoa. Like other radiolarians, it comprises large marine cells with axopods and cytoplasm differentiated into a clear inner layer (endoplasm) and a vacuolated outer layer (ectoplasm), separated by a capsular membrane. Here the axopods are fixed in number and supported by microtubules arising from unspecified sites in the cell, and the mitochondria have tubular cristae. Reproduction is by formation of spores, which may be flagellate, that develop into mononucleate amoebae. Adults usually have many nuclei. [eng] |
