Which Are Protostomes. Mouth first) are a huge clade of animals that includes the ecdysozoans ( arthropods, nematodes, and friends), platyzoa ( flatworms and allies), and lophotrochozoa (molluscs, annelids, and allies). A protostome is a group of animals that includes invertebrates like arthropods (insects and crabs), molluscs (clams and snails), and worms of phylum annelida. Protostomes are primitive invertebrates while deuterostomes include echinoderms and chordates. This division helps in understanding relationships of different groups of animals.
