Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Scorpaeniformes Cottidae

Scientific Name: Cottus rhenanus Freyhof, Kottelat & Nolte, 2005
Taxonomic Notes: Although C. rhenanus can be distinguished from individual C. gobio populations adjacent to its distribution, it can at present be diagnosed from C. gobio as a whole only by the shape of the first dorsal and by molecular characters. Further work on C. gobio is likely to show it comprises several distinct lineages and once this is resolved, C. rhenanus may become identifiable also by other characters.
