A trochophore (or trocophore) is a type of larva with several bands of cilia. By moving their cilia rapidly water eddy is created. In this way they control the direction of their movement. Additionally, in this way they attract their food in order to capture it more easily. Trochophores are found in the trochozoan phyla, which include the entoprocts, mollusks, annelids, echiurans, and sipunculans. Together, these make up part of the Lophotrochozoa; it is possible that trochophore larvae were present in the life cycle of the group's common ancestor. Trochophore larvae are often planktotrophic; that is, they feed on plankton. Image File history File links This is a lossless scalable vector image. ...

Trochophore - Wikipedia, the free encyclopedia (75 words)
A trochophore (or trocophore) is a type of larva with several bands of cilia.
They are found in certain mollusks, annelids, and a few other phyla.
Together, these make up part of the Lophotrochozoa; it appears trochophore larvae were present in the life cycle of the group's common ancestor.
