Xenambulacraria is a proposed clade of animals with bilateral symmetry as an embryo, consisting of the Xenacoelomorpha (i.e., Xenoturbella and acoelomorphs) and the Ambulacraria (i.e., echinoderms and hemichordates).[1]
They can be sister to the Nephrozoa (sans Ambulacraria), the Protostomes and Chordates. Xenambulacraria could also be sister to the Chordates[1][2][3]
- Other members of the Xenambulacraria
-
Various Acoelomorpha (nemertodermatids). -
Various Hemichordata (enteropneusts).
