Description
Definition Water parcels in which larvae of various worm taxa aggregate and are the dominant form of zooplankton. Many worm larvae are difficult to identify. The initial larval stage of annelids (the rounded, ciliated trochophore stage) is very similar to the trochophore stage of larval mollusks. Annelid larvae will continue growth by adding segments, however, and become more worm-like.
