| Abstract |
The gobiid fish Gobius gasteveni, hitherto known only from 39 specimens found in the English Channel, at Madeira and the Canaries, was found in fairly good numbers on the north-western Spanish coast. This first record for the continental European fauna allows us to recognize and describe for the first time the normal and defensive live coloration, as well as the diet of this species. The general coloration is orange-brown, pale or dark depending on mood, with 6 to 9 darker blotches along the lateral mid line. The high colour contrast in the defensive mood shows a conspicuous white terminal fringe of the dorsal fins, and also sparse light-blue spots on the membrane. The diet is based mainly on crustacea, with a high percentage of the decapod Pisidia longicornis, and polychaetes. |
