Description
I can not believe that such a beautiful geometry in nature can be only a coincidence.
he Phaeodarea are a group of amoeboid Cercozoa . They are traditionally considered radiolarians ,[1] but in molecular trees do not appear to be close relatives of the other groups, and are instead placed among the Cercozoa .[2] They are distinguished by the structure of their central capsule and by the presence of a phaeodium, an aggregate of waste particles within the cell.
The term "Radiozoa" has been used to refer to radiolaria when Phaeodarea is explicitly excluded.[3]
Phaeodarea produce hollow skeletons composed of amorphous silica and organic material, which rarely fossilize. The endoplasm is divided by a cape with three openings, of which one gives rise to feeding pseudopods , and the others let through bundles of microtubules that support the axopods . Unlike true radiolarians, there are no cross-bridges between them. They also lack symbiotic algae , generally living below the photic zone , and do not produce any strontium sulphate .
