The oceanic anglerfishes (Lophiiformes: Ceratioidei) are among the most diverse and ecologically distinctive groups of deep-sea fishes, exhibiting some of the most extreme morphological adaptations in the marine realm. Despite their remarkable biological traits, they remain among the most understudied vertebrates globally, primarily due to the logistical challenges associated with accessing their natural habitats. Here we report the diversity of oceanic anglerfishes collected during the AMAZOMIX scientific cruise, conducted in 2021 off northern Brazil, including the Amazon River plume, across depths ranging from the surface to approximately 1200 m. A total of 34 ceratioid specimens, representing six families and eight genera, were collected. Seven species were identified: Melanocetus johnsonii (Melanocetidae), Haplophryne mollis (Linophrynidae), Lophodolos acanthognathus, Oneirodes carlsbergi (Oneirodidae), Centrophryne spinulosa (Centrophrynidae), Gigantactis vanhoeffeni and Rhynchactis leptonema (Gigantactinidae). Haplophryne mollis, L. acanthognathus, C. spinulosa, and R. leptonema are reported for the first time in Brazilian waters. This study provides morphological and distributional remarks for all identified species and presents an updated checklist of deep-sea anglerfishes recorded in Brazilian waters.

The Arctic, once a climate victim, is now becoming a climate stressor. The melting ice has brought us closer to climate tipping points and, simultaneously, has made oil reserves in the Arctic more accessible. As a result, a clash has emerged between scientific warnings and climate change obstruction (CCO) discourses that prioritise economic ambitions over climate concerns. This study investigates whether, despite scientific warnings, Norway defends further oil extraction in the Arctic, thus aligning with CCO discourses by prioritising economic interests over climate urgency. Based on a qualitative inductive approach, we analyse four official White Papers from the Norwegian government, identify their discursive patterns and contrast them with CCO discourses found in the literature. We found that the Norwegian government exhibits an affinity with six CCO discourses: 1) Non-Transformative Discourse, 2) Responsibility Deflection Discourse, 3) Discourse of the Common Good, 4) Discourse of Higher Priorities or Loyalties, 5) The Legal Discourse, and 6) The Discourse of Good Intentions. We conclude that the Norwegian government has constructed a narrative where the recognition of climate urgency does not mean the renouncement of its long-term petroleum interests and further oil extraction in the Arctic. This narrative, named here as the “green oil” narrative, uses renewable energies to electrify the oil industry, thus presenting renewables as an ally of oil expansion rather than a step toward a fossil fuel phase-out. Overall, Norway’s current narrative fails to address oil dependency, defending and justifying oil extraction in the Arctic.
