2. Rhizaria is one of the five supergroups of protists, made up mostly by unicellular eukaryotes They exist in a great variety of physical forms, but most of them are amoeboids that have pseudopods supported by microtubules Pseudopodia are thread like extensions protruding from all parts of the cell that are used in mobilization and capturing prey Most but not all rhizaria have a complex outer shell and a mitochondria Rhizaria were discovered in 2002 by Cavalier-Smith

3. Rhizaria is made up of three main eukaryotic groups: chlorarachniophytes, forams, and radiolarians Chlorarachniophytes and forams have a closer common ancestor than radiolarians Forams are amoeboids with reticulose pseudopods Radiolarians are amoeboids with axopods Chlorarachniophytes are a form of cercozoa, a group of amoebae and flagellates with filose pseudopods

4. A species of rhizaria known as Naegleria fowleri is a very dangerous form of amoeba found in the Southern United States It thrives in warm fresh water of lakes, rivers, hot springs, and soil It is a brain-eating parasite that is inhaled through the nose and travels into the brain Most active in the summer, it was responsible for the deaths of three Americans in the south east

5. Scientists are attempting to genetically reprogram amoeba to attack and consume harmful bacteria in soil to benefit crops Since they naturally eat bacteria for food source, scientists believe that they can alter them to target certain harmful strains and use them for many agricultural and medical applications
