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 BilateriaB) Eumetazoa and LophotrochozoaC) Deuterostomia and EcdysozoaD) Deuterostomia and Lophotrochozoa

Answer 1

Answer:

The answer is letter B. Eumetazoa and Lophotrochozoa

Explanation:

Eumetazoa and Lophotrochozoa

Because the phylum Cycliophora neither helps or harms its lobster host.
