Descrição

VIII Expedição Científica do Departamento de Biologia – Ilha do Faial - 1993. The prey remains found around the dens of 6 octopus (Octopus vulgaris) were collected during the "Expedition Faial-93" (28 June to 3 July 1993) in "Reserva do Monte da Guia" by SCUBA diving (total of 4 dives). Based on this very preliminary work, the small crabs (Xantho spp.), bivalves (Limaria hians), and ormers (Haliotis tuberculata), seems to be the most important food items in the octopus feeding regime. Drill holes made by the octopus were observed on crab carapaces and chelipeds, but were not found on molluscan shells. The drill holes on the chelipeds or crabs are reported for the first time.
