ON THE OCCURRENCE OF PARABLENNIUS-SANGUINOLENTUS (PISCES, BLENNIIDAE)ON THE PORTUGUESE COAST

In this paper we report for the first time the occurrence of Parablenn ius sanguinolentus in mainland Portuguese waters. Since this species i s common in the Mediterranean and in the Bay of Biscay, there appears to be a distributional gap along the Portuguese coast. The present fin ding, together with recent data on the occurrence of several other ble nniids in the Atlantic coast of the Iberian Peninsula, formerly suppos ed to be Mediterranean endemics, stresses the urgent need for detailed zoogeographical investigations on the inshore fish fauna of south-wes t Europe.
