Answer:

answer

metameric segmentation The repetition of organs and tissues at intervals along the body of an animal, thus dividing the body into a linear series of similar parts or segments (metameres). Metameric segmentation is thought to have arisen as an adaptation to more efficient locomotion

Answer:

Metamerism is first seen in annelids in animal kingdom. Each segment usually con­tains appendages, muscles, nerves, blood vessels, excretory organs and a pair of coelomic sacs which are repeated in almost all segments. It is also seen in kinorhynchs, arthropods and most chordates.

features:-

1. Metamerism is always confined to the intermediate (trunk) segments except the anterior acron (head) and a poste­rior pygidium or telson.

2. Each metamere represents a mirror image of the other.

3. Segmental structures are interdepend­ent on each other.

4. They are integrated into a single func­tional unit.

5. All the segments of body work in co­ordination
