Unusual shallow inshore records of Cornish blackfish Schedophilus medusophagus (Stromateoidei: Centrolophidae) from Galician waters (NW Spain)
Three shallow inshore records of Cornish blackfish Schedophilus medusophagus from Galician Waters (NW Spain) are reported. S. medusophagus is a relatively rare mesopelagic species in the NE Atlantic. Adult specimens are mainly found in medium-depth waters (300-900 m). Their presence in shallower coa...
