The coastal octopus at Saint Paul and Amsterdam Islands is Octopus vulgaris Cuvier 1797, and the range of the species is expanded to include the oceanic islands of the central southern Indian Ocean.

Taxonomic affiliation of parasites and trophic ecology in the sampling area suggest that N. couchii is the intermediate host for B. balenae, and it is suggested that the whales Balaenoptera physalus and B. acutorostrata are its definitive hosts.
Nyctiphanes couchii as intermediate host for Rhadinorhynchus sp. (Acanthocephala, Echinorhynchidae) from NW Iberian Peninsula waters.

The morphological and phylogenetic analyses suggested that the status of Rhadinorhynchus pristis should be re-examined and the presence of these cystacanths in different mesozooplankton communities throughout the study suggests that the recruitment of parasites may be affected by the oceanography.

The hypothesis that multiple O vulgaris‐like species are currently being incorrectly treated under a single species name, O. vulgaris, is supported.
Life strategies of cephalopod paralarvae in a coastal upwelling system (NW Iberian Peninsula): insights from zooplankton community and spatio‐temporal analyses

The early life stages of cephalopods - octopods, squids, sepiolids and ommastrephids -, are uncommon in zooplankton samples and little is known about their life strategies. Accordingly, cephalopod…

New insights into the morphology, reproduction and distribution of the large-tuberculate octopus Graneledone macrotyla from the Patagonian slope

The simultaneous occurrence of oocyte cohorts at different oogenic stages suggests that the large-tuberculate octopus Graneledone macrotyla is a multiple spawner.
Macroparasites of allis shad (Alosa alosa) and twaite shad (Alosa fallax) of the Western Iberian Peninsula Rivers: ecological, phylogenetic and zoonotic insights

The results provide information about host migration behaviour and transmission pathways through diet during the marine trophic phase of the shad’s life cycle and their roles as paratenic or final hosts and transporters of parasites between seawater and freshwater environments.

Genetic results support the presence of Octopus americanus Monfort, 1802 (formerly known as O. vulgaris type II) along the Yucatan continental shelf, a new octopod extending from the north of Argentina to the northwest coast of the USA.
