Biological surveys reveal unexpectedly high faunal diversity at Nankai Trough methane seeps

open access: yesEcosphere, Volume 16, Issue 11, November 2025.
Abstract Cold seeps are chemosynthesis‐based ecosystems powered by microbial primary production that support diverse and specialized faunal assemblages in the deep sea. Despite Nankai Trough in Japan being a geologically active margin hosting numerous seeps, much of the faunal diversity remains undocumented.

Notes on fauna associated with an opportunistic artificial reef near cold-water corals [PDF]

open access: yes, 2012
This short communication provides a sporadic insight on the importance of a hard three-dimensional structure for deepwater fish near CWC. Fish size and behaviour inside the structure and in the surrounding area are described.

Identification of the polyp stage of three leptomedusa species using DNA barcoding [PDF]

open access: yes, 2017
DNA sequence data of hydromedusae and hydroids collected in the fjords near Bergen, Norway, permitted to connect three leptomedusae to three thecate hydroids with hitherto unknown life cycles.

Advancing aquatic biodiversity assessments of invertebrates using eDNA metabarcoding: A systematic evaluation of primers for marine and freshwater communities

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2408-2430, October 2025.
Abstract Invertebrate richness and community composition are key indicators of aquatic ecosystem health. Compared with morphotaxonomy‐based survey methods, DNA metabarcoding is a highly efficient and scalable biomonitoring approach that has become increasingly used in invertebrate surveys.

Some thecate hydroids (Cnidaria: Hydrozoa) from off New Caledonia collected during KANACONO and KANADEEP expeditions of the French Tropical Deep-Sea Benthos Program

open access: yesEuropean Journal of Taxonomy, 2019
Thirty-six species of various thecate hydroids occur in two recent, deep-water collections from off New Caledonia. Of these, nine are new, namely Solenoscyphus subtilis Galea, sp. nov., Hincksella immersa Galea, sp.

Phylogenetics of Hydroidolina (Hydrozoa: Cnidaria) [PDF]

open access: yes, 2017
Hydroidolina is a group of hydrozoans that includes Anthoathecata, Leptothecata and Siphonophorae. Previous phylogenetic analyses show strong support for Hydroidolina monophyly, but the relationships between and within its subgroups remain uncertain.

Estructura poblacional del zooplancton gelatinoso en el mar ecuatoriano

open access: yesRevista Científica de Ciencias Naturales y Ambientales, 2019
El presente estudio analiza la composición y distribución del zooplancton gelatinoso en el mar ecuatoriano desde Julio 2017 hasta Abril 2018. Se dividió el perfil costero en dos zonas: la ZI abarcó la provincia de Esmeraldas hasta la parte norte de la ...
