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:
- The biologist studied the Entoprocta collected from the dock pilings.
- Entoprocta are often found in colonies attached to submerged surfaces.
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.
- A single entoproct is rarely more than a few millimeters tall.
Synonyms
- Kamptozoa: An alternative name for the same taxonomic group.
- Goose barnacles (informal, but inaccurate): While sometimes confused due to a similar sessile lifestyle, this is a common misidentification; true goose barnacles are crustaceans.
Related Terms
- Bryozoa: The phylum to which Entoprocta are sometimes considered related or subordinate.
- Ectoprocta: A related but distinct group of bryozoans where the anus lies outside the tentacular crown.
- Lophophore: The feeding structure common to entoprocts and related phyla.
