Five species of the shell-morphologically defined genus Granuliterebra Oyama, 1961, together with the shell-morphologically allied taxon Duplicaria tricincta (E. A. Smith, 1877), are revised and the species are compared to a new species from Australia described herein.

An integrative study of deep-sea Typhlotanaidae revealed extensive morphological convergence and hidden genetic diversity. Three new genera and four species are described from Pacific localities, highlighting complex evolutionary relationships and possible trans-Pacific connections among geographically distant deep-sea populations.

A new species of Hastula is described from South Korea, with general shell-morphological features fitting the Hastula strigilata-complex, and is mainly compared with congeners from southern Japan and Indonesia

A coordinated survey of five methane seeps in Japan’s Nankai Trough documented 80 macro- and megafaunal species, over five times previous records. The findings reveal exceptional, depth-segregated biodiversity and provide crucial baselines for conservation amid growing methane hydrate exploitation.

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.

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.
