Triglopus xenostethus is a small marine fish from the Cottidae family. It lives on the bottom of cold northern seas and has large eyes and spines on its body.
Triglopus xenostethus differs from other gurnards with its special belly structure and large number of spines. It is important for marine nature as a predator of small invertebrates and food for larger fish.
Immature form that undergoes metamorphosis before adulthood.
