Definition

Noun A taxonomic category (phylum) of aquatic invertebrate animals, also known as Ectoprocta, which is coextensive with or considered a subphylum of Bryozoa. These are small, colonial animals that live in interconnected units (zooids), typically within a secreted exoskeleton, and feed by filtering food particles from the water using a crown of tentacles called a lophophore.

Usage

The term is used in scientific classification (taxonomy) and zoology to refer to this specific group of animals. * Modern taxonomic studies often place the phylum Ectoprocta within the larger superphylum Lophotrochozoa. * The phylum Ectoprocta includes many species that form important structural components of marine habitats.

Advanced Usage

• The name "Ectoprocta" (from Greek , "outside," and , "anus") refers to the anatomical feature where the anus lies outside the ring of tentacles (lophophore). This distinguishes them from the Entoprocta, another phylum of similar-looking animals.

Variants and Related Words

• Ectoprocta (noun): The synonym for the phylum; often used interchangeably.
• Bryozoa (noun): The traditional, broader phylum name that includes Ectoprocta. In some classifications, Bryozoa and Ectoprocta are considered synonymous.
• Bryozoan (noun/adjective): A member of this phylum; relating to this phylum.
  • Example: A bryozoan colony was found on the submerged rock.
• Moss animal (noun): A common name for these organisms, referring to their plant-like, mossy appearance.

Synonyms

• Ectoprocta
• (In many classifications) Bryozoa

Related Phrases/Concepts

• Colonial organism: A key characteristic, as ectoprocts are not solitary animals but form colonies of many genetically identical individuals (zooids).
• Lophophore: The feeding structure common to this and related phyla.
• Zooid: The individual animal unit within the colony.
