Phylum Annelida

Segmented Worms

Segmented worms are a complex group of animals related to earthworms, possessing segmented bodies, complete digestive tract, complex nervous system, and bristle-like setae used for locomotion. They may either be active or sedentary, free-living or tube-dwelling, with a variety of feeding methods.

Setae are sharp, deliver painful wounds and difficult to remove. Don't touch!
