 * Giribet (2015) – hypothetical phylogeny with red (unstable position), blue (stable position, but disagreement) and green (widely supported) clades. Red includes the mesozoan phyla and cycliophora (both within Spiralia) and Scalidophora. Specifies basal Ctenophores and order within Lophotrochozoa. Chaetognatha basal within Protostomia. Green includes Metazoa, Planulozoa, Xenacoelomorpha, Chordata, Protostomia, Ecdysozoa, Spiralia, Gnathifera, Rouphozoa, Platytrochozoan and Lophotrochozoa. Blue includes Parahoxozoa, Bilateria, Nephrozoa, Deuterostomia, Ambulacraria, Nematoida, Panarthropoda, and Lophophorata.
 * Giribet et al (2016) – consensus phylogeny with polytomies where there is uncertainty (two trichotomies at base of tree, scalidophora)
 * Giribet & Edgecombe (2020) – consensus phylogeny with polytomies where there is uncertainty (two trichotomies at base of tree, scalidophora), but updated to position Chaetognatha in or as sister to Gnathifera, to place mesozoan taxa and Cyliophora within Spiralia

Constants and changes:


 * The two basal trichotomies are retained in the consensus phylogeny, although the text recognises the clade Placozoa+Cnidaria as sister to Bilateria
 * Xenacoeloporpha unchanged except phlyla Acoela and Nemertodermatida combined into Phylum Acoelomorpha
 * Deuterostomia unchanged apart from use of Tunicata for the phylum name instead of Urochordata
 * Ecdysozoa unchanged
 * Spiralia expanded to include four phyla that were previously incertae sedis in Protostomia
 * Phylum Chaetognatha is now sister to Gnathifera (or possibly basal member of)
 * The Mesozoans, Orthonectida and Dicyemida (previously Rhombozoa), are now incertae sedia in Spiralia
 * Phylum Cycliophora now incertae sedis in Platytrochozoa (possible sister to Rouphozoa)
 * Rearrangement of Lophophorata to recognise Brachiozoa
