Monoplacophora / ˌmɒnoʊpləˈkɒfərə /, meaning "bearing one plate", is a polyphyletic superclass of molluscs with a cap-like shell, inhabiting deep sea environments. Extant representatives were not recognized as such until 1952; previously they were known only from the fossil record, and were thought to have become extinct 375 million years ago. [2]
Class Monoplacophora (Deep-sea Limpets) - Earth Life
Aug 1, 2020 · The monoplacophora, common name (deep-sea limpets) are a small, but ecologically important group of single-shelled molluscs. Photogenically they are a sister group to the Aplacophora. The length of the shell in adults ranges from 3mm to 35mm. They are also know by the name Tryblidia.
ADW: Monoplacophora: INFORMATION
Monoplacophorans are small and have a single, caplike shell, giving them a limpet-like appearance. A number of their organs (nephridia, heart, etc.) are repeated serially, making them resemble metamerically-arranged species such as annelids and arthropods.
Monoplacophorans and the Origin and Relationships of Mollusks
Apr 15, 2009 · 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.
Monoplacophoran | Primitive, Shell-bearing, Marine | Britannica
monoplacophoran, (class Tryblidia), any of a group of primitive marine mollusks characterized by a single, cap-shaped shell and bilateral symmetry. The term Tryblidia is preferred over Monoplacophoran and Galeroconcha, because both latter terms are taken to include several fossil groups of uncertain relationships.
