• Metamerism is the process of having a linear series of segmented bodies which are similar to each other.

• Metamerism type of body development can be seen in annelids one of which is earthworm, tubeworms etc.
• In the annelids such as earthworms, all the body segments work together but this kind of coordination does not happen in tapeworms.
