Xenacoelomorpha

basal bilaterian clade of small and very simple animals

Xenacoelomorpha is a proposed grouping of the xenoturbellids and acoelomorph flatworms, suggested by molecular data.[2] It may be a member of the deuterostomes, [3] and may be even more basal in the Bilateria.

Xenacoelomorpha
Xenoturbella japonica, a xenacoelomorph member (xenoturbellids)
Proporus sp., another xenacoelomorph member (acoelomorphs)
