What is defense for a annelida?

Annelids, or segmented worms, have several defense mechanisms to protect themselves from predators. They can secrete mucus to create a slippery coating, making it difficult for predators to grip them. Some species also have the ability to burrow into the substrate for concealment. Additionally, certain annelids may possess bristles (setae) that can deter attackers or aid in escaping from danger.
