2. What is the related topics?Protistology, Paleontology, Paleoceanography, Climate Science, Marine Biology, Biomineralization
3. What are Rhizaria and why are they called tiny ocean explorers?Rhizaria are single‑cell organisms that live in the ocean. They have tiny, beautiful shells that help them float and move around. Because they travel through water, we think of them as little ocean explorers.
4. How do Rhizaria make their shells and what are they made of?Rhizaria build elaborate shells called tests. Some make them from silica, like glass, while others use calcium carbonate, like shells of sea creatures. These shells are strong and help protect the cells.

Eukaryotes: Organisms whose cells contain a nucleus and other membrane-bound organelles.
Phylogenetics: The study of evolutionary relationships among biological entities, often based on genetic data.
Paleoceanography: The study of the history of oceans using geological, chemical, and biological evidence.
Bioindicators: Organisms used to monitor the health and condition of an environment.
