The first deep-sea corals documented around Okinawa’s Minamidaito and Kitadaito Islands include Callogorgia cf. korema, Pleurocorallium inutile and Acanthopathes undulata. The findings extend known species distributions and highlight the need to protect these deep-sea habitats from anthropogenic impacts.

This short report provides the first observations of deep-sea corals belonging to the class Octocorallia and order Antipatharia surveyed during the KM24-03 Leg 2 cruise in the waters around Minamidaito and Kitadaito Islands in Okinawa, Japan between approximately 200 and 1,000 m.

A study of Bornean corallanid isopods identified four Argathona species, including three new species. The findings expand known diversity, reveal novel associations with four elasmobranch hosts, and transfer Alcirona grandis to Argathona, highlighting poorly documented isopod biodiversity in the Coral Triangle.

A study of the Arctic crustacean Amathillopsis spinigera expands its known range to 11–3182 m and documents its first HAUSGARTEN records after 25 years of sampling. Integrative taxonomy, ROV observations and genetic data provide new insights into its ecology and circumarctic distribution.

Museum specimens from South Africa enabled the redescription of Gnathia spongicola and discovery of two new species, G. brevicula and G. lancifera. The study increases known Gnathiidae diversity in the Temperate Southern Africa marine realm to 11 species.

A major revision of the Indo-Pacific gastropod genus Turridrupa recognises 30 species, including 15 new species. Morphological and genetic analyses support the species classifications, highlighting substantial previously overlooked diversity in tropical Indo-Pacific habitats.

An integrative study of Typhlamia from the Aleutian region reveals distinct lineages and suggests the genus may be polyphyletic. Findings highlight the Aleutian Trench as both a potential biogeographic barrier and an important hotspot for previously undocumented deep-sea diversity.

A comprehensive review of deep-water polynoid worms around Australia identifies 21 species across 12 genera, including nine new species. Morphological and molecular analyses clarify their taxonomy and evolutionary relationships, providing the first extensive account of Australia’s deep-water Polynoidae.

A comprehensive study of Southwestern Atlantic Marginellidae identifies nine living species, including six new species and a new genus, Pustinella. Combining morphology and geometric morphometrics, it reveals distinct shelf and deep-sea communities extending to 2,457 m depth.
