Accepted Answer

Lophotrochozoa is a major grouping (superphylum) of protostome animals, including Annelida, Mollusca, Nemertea, and Platyhelminthes among others. Arthropoda, which includes insects, arachnids, and crustaceans, is not considered part of the Lophotrochozoa but is instead classified under another superphylum, Ecdysozoa, characterized by animals that molt their exoskeletons.
