| An organism is considered metameric when its body is mostly formed of serially repeated anatomical units called metameres. |
|
| The term iteration is used to denote processes that result in both metameric segments and repeated ectodermal skeletal structures. |
|
| Notably, the oldest known Early Cambrian chordate Yunnanozoon had its metameric muscular units located dorsally of the notochord, although its body was laterally compressed. |
|
| The body divided into a distinct cephalon and metameric trunk. |
|
| Whilst the new paint was a good metameric match under natural light, it looked odd under a fluorescent light. |
