Composition and distribution of Munnopsidae (Crustacea, Isopoda, Asellota), collected during the KuramBio expedition 2012 from the Kuril–Kamchatka Trench area
The abyssal macrobenthos of the Kuril–Kamchatka Trench (KKT) area was sampled for the first time using a fine-meshed camera-epibenthic sledge (C-EBS) during the German–Russian KuramBio expedition 2012 (RV Sonne, 223 cruise). Crustaceans of the order Isopoda were one of the dominant macrobenthic taxa...
