to the left side: Lophophorata, \ groups along the top and right side (Nemertini through Annelida) belong to the Trochozoa.\Trochozoa: These animals are all protostomes -- the mouth develops Before the anus- Many members are worm-like, 2 largest groups of trochozoans are the mollusca and Annelida (segmented worms). Lophophorata: This group includes the Phoronida and Entoprocta (both small groups) as well as the Bryozoa ("moss" animals) and Brachiopoda (brachiopods)
Sister groups are defined as groups of the same taxonomic rank resulting from the splitting of an ancestral lineage, Here you can see that Insects and Crustaceans are closer to each other than either are to myriapods (centipedes/millipedes) and chelicerates(Most members of the subphylum Chelicerata belong to the class Arachnida, containing the spiders, scorpions, ticks, and mites)
