Pheretima exhibits both external and internal segmentation.
External segmentation:
- The body of Pheretima is externally segmented into a series of ring-like structures called segments.
- Each segment is separated by grooves or constrictions, giving the appearance of a segmented body.
- This external segmentation is easily visible on the body surface of the earthworm.
Internal segmentation:
- Internally, each segment of Pheretima is further divided into compartments or chambers by transverse partitions called septa.
- These septa extend from the body wall towards the central axis of the earthworm.
- The internal segmentation allows for efficient movement and locomotion, as well as organ specialization within each segment.
Conclusion:
Pheretima exhibits both external and internal segmentation, which is an important characteristic of this organism. This segmentation plays a significant role in its locomotion, digestion, and overall body organization.
