<h3>What is the anatomy of Earthworm?</h3>
- An earthworm is a terrestrial invertebrate and a member of the phylum Annelida.
- They have a tube-within-a-tube body structure, corresponding external and internal segmentation, and typically include setae on each segment.
- They can be found wherever the soil, water, and temperature permit.
- The body of an earthworm is composed of a digestive tube and a thick cylindrical muscular tube that forms the body.
- The body is divided into segments, and furrows on the surface of the body serve as markers for the segment boundaries.
- The top of the first segment, which encloses the mouth, is a lobe made of muscle and flesh.
