    What does a sipunculan worm look like?
    Sipunculans have a body wall similar to that of annelids but without segmentation. When threatened, they can retract their body into a shape resembling a peanut kernel - a behaviour that has given rise to the name "peanut worm". When this introvert is in the body cavity it is like the finger of a glove tucked in the wrong way around.

    How do sipunculans reproduce?
    Food particles are gathered with the tentacles and then either the entire introvert is withdrawn into the trunk and the food particles eaten, or cilia on the tentacles transfer the particles along tracts into the mouth. Sipunculans reproduce asexually and sexually, although asexual reproduction is uncommon. Fertilization takes placein the water.

    How do sipunculans differ from annelids?
    Their bodies are divided into an unsegmented trunk and a narrower, retractable section near the head, called the " introvert " or proboscis. Sipunculans have a body wall similar to that of annelids but without segmentation.
