The Blepharisma is a common ciliate found in most any pond. Is a Paramecium Harmful to Humans? Termites. Stentor was a herald of the Greek forces during the Trojan War. Radiolaria are holoplanktonic protozoa and form part of the zooplankton, they are non-motile (except when flagella-bearing reproductive swarmers are produced) but contain buoyancy enhancing structures; they may be solitary or colonial. Plus, these single-cell organisms carry thousands of copies of its genome in its busy-body; human cells carry two feeble copies. Included in this number are many ectosymbiotic and endosymbiotic species, as .
