What are a worms appendages?

Worms, particularly earthworms, do not have traditional appendages like limbs; instead, they possess bristle-like structures called setae that help with locomotion and grip the soil. These setae are located on segments of their bodies and can be extended or retracted as needed. Some worms, like polychaetes, have fleshy, paddle-like appendages called parapodia that assist in movement and respiration. Overall, their adaptations are well-suited for a burrowing lifestyle rather than for traditional appendage functions.
