Gnathifera (from the Greek gnáthos, “jaw”, and the Latin -fera, “bearing”) is a clade of generally small spiralians characterized by complex jaws made of chitin. It comprises the phyla Gnathostomulida, Rotifera and Micrognathozoa.[2] Chaetognatha has recently been recognised as closely related to the group, with it either being included within Gnathifera[2] or the broader group Chaetognathifera.[3]
Gnathiferans include some of the most abundant phyla. Rotifers are among the most diverse and abundant freshwater animals and chaetognaths are among the most abundant marine plankton.[4][5]
