ctene
Definition
- Noun:
- A locomotor organ consisting of a row of strong cilia whose bases are fused: A specialized biological structure used for movement, found in certain marine animals like comb jellies (ctenophores). It is composed of a series of powerful, hair-like projections (cilia) that are joined at their base to form a comb-like plate.
Usage Examples

Advanced Usage
- "Ctene row": Refers to a line or series of these comb plates along the body of a ctenophore.
- The animal's iridescence is caused by light diffracting through its eight ctene rows.

- Ciliary (adj): Relating to or involving cilia.
Synonyms

- Swimming plate: Another descriptive term highlighting its locomotor function.
Related Phrases
- "Beat of a ctene": Refers to the coordinated, wave-like motion of the cilia within the organ.
