Use the following information to answer the question.
The phylum Cycliophora was discovered in 1995. They are 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 via an adhesive disk and collects scraps of food from its host's feeding by capturing the scraps in a current created by a ring of cilia. The body is saclike and has a U-shaped intestine that brings the anus close to the mouth. Cycliophorans are coelomates, do not molt (though their host does), and their embryos undergo spiral cleavage.
Basing your inferences on information in the paragraph, to which clades should cycliophorans belong?
A) Eumetazoa and Bilateria
B) Eumetazoa and Lophotrochozoa
C) Deuterostomia and Ecdysozoa
D) Deuterostomia and Lophotrochozoa

Question

Quizplus · Accepted Answer

Cycliophorans are eumetazoans - multicellular organisms with true tissues - and bilaterians - animals with left and right symmetry. They are also classified as part of the Lophotrochozoa based on the presence of a feeding structure called a lophophore in some members of the phylum and their shared developmental characteristics, such as spiral cleavage.
