Varying slightly from one subclass to another, the skeletons of radiolarians are generally organized around spicules, or spines, which are sharp, dense outcroppings from the main skeletal mass. Formed from the fusion of many of these spines is the outermost skeleton, the cortical shell . Start studying Chapter 21.4 Foraminifera and Radiolarians.

During their life cycle, radiolarians absorb silicon compounds from their aquatic environment and secrete well-defined geometric networks that comprise a skeleton commonly known as a test. Radiolarians in the Sea of Okhotsk and their ecological implication for paleoenvironmental reconstructions A. Abelmann , A. Nimmergut We identiﬁed seven radiolarian species and groups related to speciﬁc water-mass characteristics, depth habitats, and productivity regimes.

The nucleus of many radiolarians exhibits a high level of ploidy (more than 1,000 haploid chromosome sets). As a result, there is a large amount of DNA. Radiolarians reproduce by division.

Usually composed of silica, the test is elaborately perforated in a variety of patterns, forming a series either of latticelike plates or of loose needle-shaped spicules. 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.

A characteristic feature of the group is the capsule, a central mass of cytoplasm bearing one or more nuclei, food reserves, and metabolic organelles.
