Nephrozoa is a proposed major clade of bilaterian animals. It includes all bilaterians other than Xenacoelomorpha. It contrasts with the Xenambulacraria hypothesis, which instead posits that Xenocoelomorpha is most closely related to Ambulacraria. [1] [2] [3] [4] [5] Which hypothesis is correct is controversial. Authors supporting the Xenambulacraria hypothesis have suggested that the genetic evidence used to support Nephrozoa may be due to systematic error. [1]

Below is a proposed phylogenetic tree of Nephrozoa:
