The two branches are ecologically, morphologically and molecularly divergent (Bleidorn et al. Adults of Nectonema have dorsal and ventral double rows of swimming bristles, while those of Gordiida lack bristles (except for, in some species, Nematomorpha; Nematoda; Sinonim; Nematoidea Rudolphi, 1808; Nematozoa Zrzavý et al. This simple classification, however, although useful in certain circumstances, breaks down in many cases, such as ‘mesoparasitic’ copepods that are partially embedded in host tissues but still exposed to the external aquatic habitat (Boxshall and Halsey, 2004). The 19 genera within the phylum Nematomorpha contain approximately 350 species. , was discovered from Kenya, Africa, and appears to have solved the problem of being trapped without a mate by eliminating the need for males.
