Question
Chapter 15, Problem 7RQ
Summary Introduction
To determine: The orientation of the valves of brachiopod in terms of the dorso-ventral axis.
Introduction: In ectoprocts, the ciliary water currents carry food particles between the gaping valves and over the feeding organ called a lophophore. The tentacles trap the food particles and the ciliated grooves carry the particles along the arm of the lophophore to their mouth.
