A lophophore is primarily a feeding structure found in certain aquatic invertebrates, such as bryozoans and brachiopods. It consists of a crown of ciliated tentacles that encircle the mouth. The cilia create water currents that help to capture suspended food particles, such as plankton and detritus, from the water column, allowing the organism to filter feed efficiently. This adaptation is crucial for their survival, as it enables them to obtain nutrients from their environment effectively.

While sensory reception, structural support, and locomotion are important functions in various organisms, the primary function of a lophophore is to assist in feeding. In this case, the tentacles act not only as a means of gathering food but also play a role in respiration by facilitating gas exchange in some organisms.
