What are the 8 classes of phylum Mollusca?

The Phylum Mollusca consist of 8 classes: 1) the Monoplacophora discovered in 1977; 2) the worm-like Aplacophora or solenogasters of the deep sea; 3) the also worm-like Caudofoveata; 4) the Polyplacophora, or chitons; 5) the Pelecypoda or bivalves; 6) the Gastropoda or snails; 7) the Scaphopoda, or tusk shells; and 8) …

Where are Monoplacophora found?

deep sea
Monoplacophorans are found on both soft bottoms and hard substrates on the continental shelf and seamounts, generally in the very deep sea. However, some Paleozoic taxa are associated with relatively shallow water faunas (greater than 100 m), indicating that their relegation to the deep sea is a more recent phenomenon.

How many species of Monoplacophora are there?

At present, 11 species are known. Most live at great depths and all are marine. Monoplacophorans are small and have a single, caplike shell, giving them a limpet-like appearance.

What is the common name for Monoplacophora?

The monoplacophora, common name (deep-sea limpets) are a small, but ecologically important group of single-shelled molluscs.

What makes Monoplacophora unique?

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).
