First records of two decapod crustaceans, the caramote prawn Penaeus kerathurus and the blue crab Callinectes sapidus from Galician waters (NE Atlantic)

摘要

Two unusual crustacean decapods are reported for the first time from the coasts of Galicia (NW Spain). A specimen of caramote prawn Penaeus kerathurus (Penaeidae) was caught in the Ria de Arousa in 2014 and a specimen of blue crab Callinectes sapidus (Portunidae) was caught in the Ria de Vigo in 2015, the first one being a native species whereas the second is an exotic one. A tropicalization process due to ocean warming could favour the arrival of warm water species to temperate latitudes as well as the establishment of introduced species.
