“…Both are caught by small-scale operators, and sold in local markets, although most of the catch is exported to Asia and Europe. Other benthic octopus such as Muusoctopus eicomar (Vega, 2009), Muusoctopus longibrachus (Ibáñez, Sepúlveda and Chong, 2006) and Graneledone boreopacifica are common as bycatch in the crustacean fisheries in Chile (Ibáñez et al, 2006(Ibáñez et al, , 2011(Ibáñez et al, , 2012(Ibáñez et al, , 2016. Artisanal fishers occasionally catch the smallsized octopus R. fontaniana, but despite the species does not represent a commercial resource (Osorio et al, 1979, Ibáñez et al, 2008, it constitutes an important aquaculture candidate in Chile as its small size ("baby octopus") is very attractive for Asian and European markets (Uriarte et al, 2011).…”

“…The finding of reciprocal monophyly and species delimitation analyses suggested that the subspecies G. taniwha taniwha and G. taniwha kubodera are different species. Both subspecies have similar morphological features, including suckers, gills, and wart counts (Ibáñez et al, 2012). O'Shea (1999) suggested that future descriptions of Graneledone species should provide more morphological detail (cartilaginous cluster distribution and composition, and arm sucker counts), and proposed that the only way to differentiate these two species is by the number of cartilaginous processes per cluster (i.e., G. taniwha taniwha 1-37 and G. taniwha kubodera 4-13).…”

Systematics and Phylogenetic Relationships of New Zealand Benthic Octopuses (Cephalopoda: Octopodoidea)

The systematics of the New Zealand octopods have only been reviewed twice in the last 100 years. In these revisions many species have been provisionally classified in the genus Octopus. Recent genetic studies have synonymized some New Zealand species with octopuses from other regions. The present study investigates the systematics and phylogeny of octopuses from New Zealand using eighty eight specimens, three mitochondrial genes (16S rRNA, cytochrome c oxidase subunit I, and cytochrome c oxidase subunit III) and one nuclear gene (Rhodopsin). Forty-four new octopod DNA sequences (belonging to 13 species) were included, adding to the 83 existing sequences from GenBank. All sequences were used to generate phylogenetic trees based on Maximum Likelihood (ML) and Bayesian inference (BI), with a data set composed by 97 species, including octopod sister groups and Vampyroteuthis infernalis as an outgroup. Gene tree and species delimitation analyses revealed a distinct genetic difference between two sympatric Graneledone subspecies, which we propose as valid species. Muusoctopus tangaroa is a sister species of M. thielei from Kerguelen; while Enteroctopus zealandicus forms a clade with E. megalocyathus from South America and E. dofleini from the North Pacific. Similarly, Octopus campbelli, O. huttoni, and O. mernoo form a monophyletic group with Robsonella fontaniana from South America, Scaeurgus unicirrhus from the Atlantic and O. pallidus from Australia. Pinnoctopus cordiformis is close to Grimpella thaumastocheir and several species of Octopus sensu lato as in previous phylogenetic studies. This study suggests that octopuses from New Zealand have different phylogenetic and biogeographic origins and represent independent radiations into this region.

“…Another ROV survey led to the first report of antipatharian black corals on the shelf break off La Higuera (∼29 • S, 70-107 m depth) (Gorny et al, 2018). Other methods of benthic studies in the area include studying species collected as bycatch from deep-water Patagonian Toothfish and crustacean fisheries (e.g., Ibáñez et al, 2006Ibáñez et al, , 2011Ibáñez et al, , 2012Ibáñez et al, , 2016Araya, 2013Araya, , 2016.…”

Species That Fly at a Higher Game: Patterns of Deep–Water Emergence Along the Chilean Coast, Including a Global Review of the Phenomenon

Deep-water emergence (DWE) is the phenomenon where marine species normally found at great depths (i.e., below 200 m), can be found locally occurring in significantly shallower depths (i.e., euphotic zone, usually shallower than 50 m). Although this phenomenon has been previously mentioned and deep-water emergent species have been described from the fjord regions of North America, Scandinavia, and New Zealand, local or global hypotheses to explain this phenomenon have rarely been tested. This publication includes the first literature review on DWE. Our knowledge of distribution patterns of Chilean marine invertebrates is still very scarce, especially from habitats below SCUBA diving depth. In our databases, we have been gathering occurrence data of more than 1000 invertebrate species along the Chilean coast, both from our research and from the literature. We also distributed a list of 50 common and easily in situ-identifiable species among biologically experienced sport divers along the Chilean coast and recorded their sighting reports. Among other findings, the analysis of the data revealed patterns from 28 species and six genera with similar longitudinal and bathymetric distribution along the entire Chilean coast: along the Chilean coast these species are typically restricted to deep water (>200 m) but only in some parts of Chilean Patagonia (>39°S–56°S), the same species are also common to locally abundant at diving depths (<30 m). We found 28 of these ‘deep’ species present in shallow-water of North Patagonia, 32 in Central Patagonia and 12 in South Patagonia. The species belong to the phyla Cnidaria (six species), Mollusca (four species), Arthropoda (two species) and Echinodermata (16 species). We ran several analyses comparing depth distribution between biogeographic regions (two-way ANOVA) and comparing abiotic parameters of shallow and deep sites to search for correlations of distribution with environmental variables (Generalized Linear Models). For the analyses, we used a total of 3328 presence points and 10635 absence points. The results of the statistical analysis of the parameters used, however, did not reveal conclusive results. We summarize cases from other fjord regions and discuss hypotheses of DWE from the literature for Chilean Patagonia.
