- Monoplacophora - Wikipedia
Monoplacophora ˌmɒnoʊpləˈkɒfərə , meaning "bearing one plate", is a polyphyletic class of molluscs with a cap-like shell, inhabiting deep sea environments
- Monoplacophora | INFORMATION | Animal Diversity Web
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
- Monoplacophoran | Primitive, Shell-bearing, Marine | Britannica
Monoplacophorans are unusual because of the combination of primitive characteristics that they possess In addition to the single, cap-shaped shell, they have paired multiple organs, reflecting at least partial segmentation (metamerism)
- Monoplacophora - an overview | ScienceDirect Topics
There are currently seven classes of mollusc recognized (Aplacophora, Monoplacophora, Polyplacophora, Bivalvia, Gastropoda, Scaphopoda, Cephalopoda) and nearly all species within these taxa reproduce sexually, a process that requires males to produce spermatozoa
- The Monoplacophora - University of California Museum of . . .
Once known only from Paleozoic fossils, living monoplacophorans were discovered in 1952 in one of the most important discoveries in modern biology Since that first recent species (Neopilina galathaea) was discovered, around 20 other species have been identified
- Class Monoplacophora (Deep-sea Limpets) - Earth Life
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
- Monoplacophorans and the Origin and Relationships of Mollusks
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
