The Phylum Protozoa is further organized into finer groupings including:
- Class (5): Granuloreticulosea · Heliozoa · Labyrinthulea · Lobosa · Protozoa
- Species: ZipcodeZoo has pages for 30 species and subspecies in the Phylum Protozoa.
The Foraminifera ("hole bearers"), or forams for short, are a large phylum of amoeboid protists. They are among the most common marine plankton species. Forams have reticulating pseudopods, fine strands of cytoplasm that branch and merge to form a dynamic net. They typically produce a test, or shell, which can have either one or multiple chambers, some becoming quite elaborate in structure. These shells are made of calcium carbonate (CaCO3) or agglutinated sediment particles. About 275,000 species are recognized, both living and fossil. They are usually less than 1 mm in size, but some are much larger, the largest species reaching up to 20 cm. [more]
At least 19 species and subspecies belong to the Class Protozoa.
