... ( Lithelius sp., Rhizosphaera trigonacantha and Arachnosphaera hexasphaera ) were stained and emitted green fluorescent light. Staining of the skeleton was probably the result of skeletal thickening growth, whereas staining of the pseudopodia may indicate that siliceous matter is assimilated within...

... they control silica secretion with pH regulation ( Coradin and Lopez 2003 ). Using PDMPO, an acidophoric fluorescent compound, Ogane (2009) demonstrated that similar silica deposition vesicles also exist in extant radiolarian species such as Rhizosphaera trigonacantha and Spirocyrtis scalaris . Seawater...
