- Earthworms are classic examples of metameric animals.
- The metameric organization of the lobster's body is evident in its repeated appendages.
- In biology class, we studied the metameric segmentation of certain invertebrates.

Variants and Related Words
- Metamere (noun): An individual body segment or unit in a metameric animal.
- Each metamere in an earthworm contains a set of repeated organs.
- Metamerism (noun): The state or condition of being metameric; segmentation.
- The principle of metamerism is fundamental to understanding annelid anatomy.
Synonyms
- Segmented: Divided into segments.
- Modular: Composed of standardized units or sections (used more generally in biology and design).
Notes on Meaning
- The term is primarily used in zoology and biology. It is a technical, scientific descriptor and is not commonly used in everyday language.
