Protista is a collection of single-celled eukaryotic organisms and simple multicellular forms some animal-like … Radiolarians are unicellular protists that build external, glassy skeletons (tests) of silica. Their intricate tests come in various shapes and often have delicate spikes and projections that help increase buoyancy. Most radiolarians live as single cells, but some form long colonies up to 1 meter long. The Radiolaria, also called Radiozoa, are protozoa of diameter 0.1–0.2 mm that produce intricate mineral skeletons, typically with a central capsule dividing the cell into the inner and outer portions of endoplasm and ectoplasm. The elaborate mineral skeleton is usually made of silica. They are found as zooplankton throughout the global ocean.

Radiolarians Marine planktonic unicellular eukaryotes Present in all oceans at all depths Most species occur solitarily ranging in size between 30 - 300 microm Their diversity and abundance in a geographical region is related to variables such as temperature, salinity, productivity, and availability of nutrients. Unicellular organisms consist of both prokaryotic (bacteria, archaea) and eukaryotic (Protozoa, unicellular algae, unicellular fungi,) cell type microorganisms. The life span of unicellular organisms is short as compared to the multicellular organisms due to the high workload. A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of multiple cells.

Radiolarians are unicellular predatory protists encased in elaborate globular shells, typically between 0.1 and 0.2 millimetres in size, usually made of silica and pierced with holes.

Radiolarians are unicellular predatory protists encased in elaborate globular shells, typically between 0.1 and 0.2 millimetres in size, usually made of silica and pierced with holes. Their name comes from the Latin for "radius". Two major subclassifications of Rhizaria include Forams and Radiolarians.

Radiolarians, which are mostly spherically A second subtype of Rhizaria, the radiolarians, exhibit intricate exteriors of glassy silica with radial or bilateral symmetry (Figure 15). Red algae are common in Foraminifera are tiny single-celled, shell-covered organisms, usually between a millimeter When radiolarians die, their shells sink to the bottom of the ocean.
