What are Trochophore larvae?
Trochophore, also called trochosphere, small, translucent, free-swimming larva characteristic of marine annelids and most groups of mollusks. Trochophores are spherical or pear-shaped and are girdled by a ring of cilia (minute hairlike structures), the prototroch, that enables them to swim.Click to see full answer.

Herein, what Phylums have Trochophore larvae?Trochophores exist as a larval form within the trochozoan clade, which include the entoprocts, molluscs, annelids, echiurans, sipunculans and nemerteans. Together, these phyla make up part of the Lophotrochozoa; it is possible that trochophore larvae were present in the life cycle of the group’s common ancestor.Secondly, do arthropods have Trochophore larvae? Until very recently, the Arthropoda (insects & crustaceans) were considered possible close relatives of the Annelida, based on the fact that both groups are segmented, but no arthropod has a trochophore larva and no molecular studies support a close relationship. Regarding this, do annelids have Trochophore larvae? Annelids are bilaterally symmetrical and do not shed their body covering. Those characteristics and features of development puts them in the Lophotrochozoan lineage, with molluscs being their most closely related phyla. For example, most have trochophore larvae.What is a free swimming larval stage called a Trochophore?Mollusks are soft-bodied animals that usually have an internal or external shell. Many aquatic mollusks have a free-swimming larval stage called trochophore.
