Is a worm a mollusc

Answer 1

annelids-derived from the latin word annellus which means little ring the name refers to the ring-like appearance of annelids' body segments. The body of an annelid is divided into segments that are separated by septa (singular: Septum), which are internal walls between each segment. Most segments are similar to one another, although they may be modified to preform special functions. Some body segments may carry one or more pairs of eyes, several pairs of antennae, and other sense organs. Other segments may be specialized for functions such as respiration. In many annelids, bristles called setae (singular: Setae) are attached to each segment.
