Caudofoveata is a small class of the phylum mollusca, also known as Chaetodermomorpha. The class is often combined with Solenogastres and termed Aplacophora. The class first emerged in the Silurian era. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...

Phyla Mollusca Arthropoda Annelida Protostomes (from the Greek: first the mouth) are a superphylum of animals in the taxonomic group bilateria, and include animals such as arthropods, mollusks, and nematodes. ...

Caudofoveata are small (1-30 mm), primitive deep sea molluscs. They are worm-like, lacking shells or distinct muscular feet; they instead have scales and calcareous spines for movement. They live by burrowing through soft sediment, and feed by lying vertically in the sediment with just the mouth-parts exposed and taking in passing organic detritus. During sexual reproduction, the female produces eggs which are fertilized and brooded, and then the larvae swim freely. To help compare different orders of magnitude this page lists lengths between 10-3 m and 10-2 m (1 mm and 1 cm). ... Sexual reproduction is a type of reproduction that results in increasing genetic diversity of the offspring. ...

The class has six families: Chaetodermatidae, Falcidentidae, Limifossoridae, Scutopidae, Metachaetodermatidae and Prochaetodermatidae. There are about 70 known species in these families.
