context_page_description: A trochophore is a type of free-swimming planktonic marine larva with several bands of cilia.
  By moving their cilia rapidly, a water eddy is created. In this way they control the direction of their movement. Additionally, in this way they bring their food closer, in order to capture it more easily.

  D - early trochophore ;
