The phylum Cycliophora includes tiny organisms that live in large numbers on the outsides of the mouthparts and appendages of lobsters. The feeding stage permanently attaches to the lobster and collects scraps of food from its host's feeding by capturing the scraps in a current created by a ring of cilia.
The feeding stage of cycliophorans is best described as ________.
A) autotrophic and captures food in a manner similar to gastropods
B) sessile and captures food in a manner similar to that of animals with lophophores
C) sessile and radially symmetric
