In the current account we report on the species of marine heterobranchs collected during the coastal monitoring mission “GAMPA Graciosa 2014” (20–26 July 2014). Sampling was carried out by SCUBA diving down to 30 m depth on 10 sampling locations. Animals were collected by hand after direct observation, and later in the laboratory separated by morpho-species, photographed, databased, and preserved after relaxation in 96% ethanol. Fourteen species were collected, of which 13 represent new records for the fauna of Graciosa Island (~93%), highlighting the need for additional sampling efforts across the whole Archipelago.
