Phylum Annelida
Next Generation Science Standards
The segmented body plan of an annelid worm with both circular and lengthwise muscles is the ideal structure for active burrowing.
Earthworms are important decomposers. Digging in the soil, earthworms both aerate and release nutrients into the soil.
Cross Cutting Concepts: Structure and Function
The body plan animation visualizes the complex annelid structures and how they function:
- A long skinny segmented body
- Circulatory and nervous system
- Circular and lengthwise muscles
- One way gut
- Setae (These are not discussed in the video, but they are clearly evident in several sequences)
