COMMENT. Etymologically, the word "gnathopoda" ("jaw-legged") fails to characterize the taxon: while in Onychophora and many Euarthropoda anteriormost pairs of limbs are specialized as jaws, in Tardigrada jaws are not limb derivatives; probably these or that limbs were specialized as jaws independently in various groups of Gnathopoda, and the common ancestor of Gnathopoda had no jaws homologous to limbs. In nomenclature, however, etymology is not a factor (see I.3.2). The name Gnathopoda Lankester 1877 is not a homonym of Gnathopodaria Pictet 1854 (originally "Gnathopodaires", in French); thus, the name Gnathopoda should be valid.
