Abstract	Litter is known to negatively affect numerous marine organisms, but the extent of such impacts is not well known for several groups, including cephalopods. Considering the ecological, behavioral and economic importance of these animals, we reviewed the types of interactions between cephalopods and litter in the scientific literature, to evaluate impacts and knowledge gaps. We found 30 papers, which included records of microplastic ingestion and the transfer of synthetic microfibers along the food web. The largest number of records involved litter use as shelter, and the common octopus was the most frequent species. At first sight, litter use as shelter could appear to be a potential positive effect, but it is necessary to clarify the implications of this choice and its long-term consequences. Regarding ingestion and trophic transfer, further research is needed to elucidate its occurrence and impacts on cephalopods and their predators, including humans.

Abstract	Seamounts and oceanic currents are important oceanographic features that influence genetic diversity of a species along its distribution, acting both as barriers or pathways for species dispersal. There are two important seamount chains in the Tropical Western Atlantic (TWA): the Fernando de Noronha Chain in northeastern Brazil and the Vitória-Trindade Chain in southeastern Brazil. This region is influenced by the North and South branches of the Southern Equatorial Current (SEC), which flow from the east to west. In order to evaluate how these oceanographic characteristics influence the genetic diversity and population structure of O. insularis along its broad distribution area, we analyzed specimens from sampling sites of the Brazilian coast and oceanic islands, Ascension and Saint Helena archipelago, Mexican Caribbean, and San Blas, Panama. The analyses performed using fragments of 659 bp of the mitochondrial gene (cox1) showed the occurrence of four distinct populations: one from Caribbean to Fernando de Noronha archipelago (Central-North), another from east coast of Brazil to Trindade archipelago (South), and the others restricted to Ascension and Saint Helena, and São Pedro and São Paulo archipelagos, respectively. Both the seamounts and ocean currents contributed to the genetic structure observed along O. insularis distribution. The bifurcation of the SEC seems to separate Center-North and South populations, while the gene flow within oceanic islands and the coast in each population is explained by the existence of seamounts. Since O. insularis has a broad distribution (mainly the Center-North population) divided into four genetically distinct fisheries, the species fishery needs to be managed accordingly, which might depend on the international policies agreements.

Abstract	Benthic octopuses have been widely documented in artificial shelters for decades, and this use is apparently increasing. Despite any possible positive effects, the use of litter as shelter could have negative implications. In this work, we aimed to elucidate the interactions of octopuses with marine litter, identifying types of interactions and affected species and regions. To achieve this, we obtained 261 underwater images from 'citizen science' records, and identified 8 genera and 24 species of benthic octopuses interacting with litter. Glass objects were present in 41.6% of interactions, and plastic in 24.7%. Asia presented the highest number of images, and most records were from 2018 to 2021. Citizen science provided important evidence on octopus/marine litter interactions, highlighting its value and the need for more investigations on the subject. This information is fundamental to help prevent and mitigate the impacts of litter on octopuses, and identify knowledge gaps that require attention.

Abstract	Octopus insularis, despite being widely fished from Brazil to Mexico, has only recently been described as a different species from the sympatric Octopus vulgaris complex in the tropical Atlantic, where its occurrence is determined by different environmental factors. Using a 10‐year time series from Brazil, we modeled how topographic aspects and oceanographic variables affected the landings of O. insularis. For that we used a locally weighted scatterplot smoothing (LOESS) technique and residual autocovariate‐boosted regression trees (RAC‐BRTs). In addition to the octopus landing per unit effort (LPUE) being driven by the seafloor structure, we also observed that it was directly related to the temperature and inversely related to chlorophyll. Higher LPUEs were observed in warmer years. Although the relationship between LPUE and chlorophyll or temperature has not yet been explained under laboratorial conditions, the higher catches observed at higher temperatures may be both a result of the local fishing dynamics and a warning toward the possibility of future niche expansion, due to climate change. If the latter is confirmed, octopus fisheries in parts of the South Atlantic would need to adapt to a smaller, and thus cheaper, body‐sized species.

Abstract	The tropical Octopus insularis is a shallow-water species widely distributed in the western Atlantic. Recent studies of niche models have identified suitable habitats for its settlement also on the east coast of the Atlantic. Considering the pelagic larval period and the high tolerance of this species to environmental variations, this study aimed to analyze the possibility of O. insularis occurrence in the West Atlantic (São Tomé Island) through molecular analyses, dispersion, and niche models. The molecular analyses were performed using fragments of 481 bp of the mitochondrial gene (cox1) from three muscle samples collected in São Tomé Island. The O. insularis long-range connectivity between South America and Western Africa was analyzed using a Lagrangian particle tracking model. Additionally, O. insularis records across its entire known distribution were applied to run the ecological niche model (ENM) using the Maxent algorithm. The Bayesian phylogenetic reconstruction showed that two of the three octopus sequences from São Tomé island (Central-Western Africa) belong to a monophyletic and well-supported O. insularis clade. The third octopus sample revealed a new species related to the clade with the Octopus vulgaris species complex. The dispersal models pointed out that passive particles could potentially reach the seamounts region at Africa coast via oceanic currents (mainly the North Equatorial Countercurrent) from São Pedro and São Paulo archipelago (Central-Western Region of the Atlantic) in a period of ∼30–60 days. This suggests that São Pedro and São Paulo archipelago could act as a potential source of paralarvae to Western Africa, although we hypothesize that this connection was more common during the Pleistocene, when sea level was around 120 m lower. In addition to the already known areas of O. insularis occurrence, the ENM pointed suitable habitats to the octopus settlement from Guinea-Bissau down to Equatorial Guinea and Gabon, and African Islands, such as São Tomé and Príncipe. The new record of O. insularis in Africa raises important questions regarding regional fisheries management. Considering that O. insularis is highly tolerant to environmental variations and very adapted to warm shallow waters, there is a possibility that octopus fisheries stocks on the African coast have a mixed composition (O. vulgaris, O. insularis, and Octopus sp.) and therefore the fisheries must follow management measures suitable for each species. In addition, further studies should be carried out in order to characterize and describe the potential new octopus species found only in São Tomé Island according to our genetic survey.

Abstract	The uplift of the Isthmus of Panama (IP) created a land bridge between Central and South America and caused the separation of the Western Atlantic and Eastern Pacific oceans, resulting in profound changes in the environmental and oceanographic conditions. To evaluate how these changes have influenced speciation processes in octopods, fragments of two mitochondrial (Cytochrome oxidase subunit I, COI and 16S rDNA) and two nuclear (Rhodopsin and Elongation Factor-1α, EF-1α) genes were amplified from samples from the Atlantic and Pacific oceans. One biogeographical and four fossil calibration priors were used within a relaxed Bayesian phylogenetic analysis framework to estimate divergence times among cladogenic events. Reconstruction of the ancestral states in phylogenies was used to infer historical biogeography of the lineages and species dispersal routes. The results revealed three well-supported clades of transisthmian octopus sister species pair/complex (TSSP/TSSC) and two additional clades showing a low probability of species diversification, having been influenced by the IP. Divergence times estimated in the present study revealed that octopod TSSP/TSSC from the Atlantic and Pacific diverged between the Middle Miocene and Early Pliocene (mean range = 5-18 Ma). Given that oceanographic changes caused by the uplift of the IP were so strong as to affect the global climate, we suggest that octopod TSSP/TSSC diverged because of these physical and environmental barriers, even before the complete uplift of the IP 3 Ma, proposed by the Late Pliocene model. The results obtained in this phylogenetic reconstruction also indicate that the octopus species pairs in each ocean share a recent common ancestor from the Pacific Ocean.

Abstract	In 2019 an oil spill spread over more than 4000 km of the Brazilian coastline. Monitoring programs that allow for the evaluation of potential impacts on communities and ecosystems and their recovery through time are needed and rely on baseline information previous to the oil spill. Here we compiled qualitative and quantitative data available from 8 studies on fish and benthic species from different habitats of Rio Grande do Norte (RN) from 2007 to 2018. We assessed the number of species from different locations and compiled information on conservation status and human use. We mapped the study areas and habitats and overlapped them with those affected by the oil spill. The RN state has a high diversity of fish (175 species) and benthic species (285 species), of which more than half of fish (52%) and 2% of benthic species are threatened and 72,8% of fish and 7,9% of benthic species are of commercial interest. Information of most habitats is still poorly known (i.e.majority ofthe available data are from unique and punctual sampling), which may weaken future evaluations of the real impact of the oil spill. Nonetheless, it is possible to design reliable monitoring based on our dataset, persistent contamination and future loss of diversity.
