A scarred octopus
Deep-sea octopuses (Graneledone boreopacifica) sometimes lurk among the basalt cliffs formed by underwater eruptions at the summit of Axial Seamount (off the coast of Oregon) like this scarred individual seen during the 2022 OOI Regional Cabled Array Operations and Maintenance expedition.
