Rotiferan Hox genes give new insights into the evolution of metazoan bodyplans [PDF]
, 2017 The phylum Rotifera consists of minuscule, nonsegmented animals with a unique body plan and an unresolved phylogenetic position. The presence of pharyngeal articulated jaws supports an inclusion in Gnathifera nested in the Spiralia.
