Entoprocta
Definition
- Noun:
- A taxonomic class or group of small, aquatic, mostly marine invertebrates: "Entoprocta" refers to a phylum or class of minute, sessile animals that are filter feeders, often superficially resembling mosses or hydroids. They are characterized by having a U-shaped gut and a crown of tentacles (lophophore) surrounding both the mouth and the anus.
Usage Examples
- Noun:

Advanced Usage
- Taxonomic Context: In some classifications, "Entoprocta" is considered a class within the phylum Bryozoa, while in others it is treated as a separate phylum.
- The phylogenetic relationship between Entoprocta and Ectoprocta is a subject of ongoing research.
Variants and Related Words
- Entoproct (n): An individual animal belonging to the Entoprocta.
