Sepiolinae (mollusca, cephalopoda) de la ría de Vigo

That work is the first one done on the Sepiolinae of an estuarine system, and a contribution to the knowledge of this subfamily in the Atlantic Ocean, where it is litle weil known. Only 30 specimens of Sepiola atlantica and 2 of Sepiola lingulata wete captured in the ria of Vigo after 3 years of sampling. ln this time 316 trawls all round the ria, and more than 500 fishing operations with a special gear to sample in shallow waters have been carried out. A redescription of the most eminent characteristics for the identification of S. atlantica are done. The morphological variability of the hectocotylus of males and of the bursa copulatrix of females that has been found is interpreted as normal modifications of a general pattern of the species. No races has been considered. Some aspects on the biology of that species, very few known, are exposed. The cite of S. ligulata confirm that the species can not be more considered as endemic of the Mediterranean sea.
