Kner's goby
Pomatoschistus knerii, Kner's goby, is a species of goby native to the western basin of the Mediterranean Sea and the Adriatic Sea.  This species occurs in areas with soft substrates near to rocks or beds of seagrass. The specific name most likely honours the Austrian ichthyologist Rudolf Kner (1810-1869), who was a friend of the author Franz Steindachner.
