Various factors affecting the depth distribution of Foraminifera and Radiolaria in the marine environment are described. We found that foraminiferan and radiolarian 2-tubulins share some of the unusual substitutions in the structurally essential and usually conserved domains. Their shells, often called tests, are chambered (forams add more chambers as they grow). description of the foraminifera Amoebae are defined based on pseudopodia type: those with thin, or filose, pseudopods, which may be reinforced by stiff microtubule proteins, are classified in the supergroup Rhizaria (e.g., foraminiferans and radiolarians), whereas those with lobose pseudopods, which are blunt and are not reinforced, are classified in the supergroup Amoebozoa. 2, p. 244. . cytoplasm.b.
