The story of the discovery and study of the Monoplacophora (or Tryblidia) and how they have contributed to our understanding of the evolution of the Mollusca highlights the importance of integrating data from the fossil record with the study of living forms. The shell ranges from 3 mm to 37 mm in diameter depending on species. Class Monoplacophora: include very primitive mollusks. Familia Neopilinidae Knight & Yochelson, 1958. The radula can be used for complex tasks, from grazing on marine algae or drilling a hole in another animal's shell. From scientific name Monoplacophora + -an. A summary of reports of abyssal and hadal Monoplacophora and Polyplacophora (Mollusca). The exterior layer of the shell does not contain defined prisms.
