Radiolaria

2013 Moorea Biocode cc-by-nc-sa-3.0

Radiolaria (Radiolarians) is a phylum of rhizarians. There are 2838 species of Radiolarians, in 862 genera and 161 families. This phylum has been around since the cambrian stage 4 age. It includes groups like Cadiidae. Dead Radiolarians form siliceous oozes. They are omnivores. They are passively mobile organisms.

Definition: Siliceous ooze is a marine sediment composed of the debris of plankton with silica shells, such as diatoms and radiolaria. This ooze is limited to areas with high biological productivity, such as the polar oceans, and upwelling zones near the equator. The least common type of sediment, it covers only 15% of the ocean floor. It accumulates at a slower rate than calcareous ooze: 0.2-1 cm / 1000 yr.
