Sulfated Polyhydroxysteroids from the Antartic Ophiuroid Gorgonocephalus Chilensis [PDF]
Molecules, 2000 Five disulfated steroids and a mixture of monosulfated steroids were isolated from the ethanolic extract of the antarctic ophiuroid Gorgonocephalus chilensis. The structures were determined by 1H-NMR, 13C-NMR and FABMS.

A new brittle star from the early Carboniferous of Poland and its implications on Paleozoic modern-type ophiuroid systematics [PDF]
Acta Palaeontologica Polonica, 2015 The fossil record of Paleozoic ophiuroids includes a number of forms which share striking similarities with modern relatives in terms of skeletal morphology.

A Silurian ophiuroid with soft‐tissue preservation [PDF]
Papers in Palaeontology, 2021 AbstractMost Palaeozoic brittle stars lack the fused arm ossicles (vertebrae) that facilitate the remarkable mode of walking that characterizes living forms. Here we describe a stem ophiuroid from the Herefordshire Lagerstätte (Silurian, Wenlock Series), which is exceptional in preserving the body cavity uncompacted and the long tube feet.

DNA Barcoding of Cold-Water Coral-Associated Ophiuroid Fauna from the North Atlantic
Diversity, 2022 In this study we focus on the ophiuroid species associated with cold-water corals south of Iceland. The specimens were sampled with the ROV Phoca (GEOMAR) in three different areas, during the recent expedition MSM75 connected to the IceAGE_RR (Icelandic ...

Availability and occurrence of coelenterazine in a Swedish fjord to maintain Amphiura filiformis bioluminescence [PDF]
Scientific ReportsThe bioluminescent European brittle star Amphiura filiformis produces blue light at the arm-spine level thanks to a biochemical reaction involving coelenterazine as substrate and a Renilla-like luciferase as an enzyme.

Chromosome-level genome assembly and single-cell analysis unveil molecular mechanisms of arm regeneration in the ophiuroid Ophiura sarsii vadicola [PDF]
Genome BiologyBackground Ophiuroids, belonging to Ophiuroidea in Echinodermata, possess remarkable regenerative capacities in their arms, relying on cellular recruitment and de-differentiation.

Contrasting cryptofaunal responses to seabird nutrient inputs illuminate coral reef productivity pathways [PDF]
Ecology, Volume 107, Issue 7, July 2026.Abstract Nutrients moving across ecosystems can propagate through food webs via distinct trophic pathways. Their integration into food webs is often mediated by small, abundant taxa that channel subsidies from primary producers to higher trophic levels.

Unveiling ophiuroid biodiversity across North Atlantic habitats via an integrative perspective [PDF]
Scientific ReportsThe depths of the North Atlantic Ocean host a species-rich fauna providing heterogeneous habitats from thermal vent fields to cold-water coral reefs. With the increasing threat of destruction of deep-sea habitats due to human impacts, such as demersal ...

The complete mitochondrial genome of a deep sea ophiuroid of the genus Amphiura (Ophiuroidea: Amphiuridae) [PDF]
Mitochondrial DNA. Part B. Resources, 2019 Amphiura is a widely distributed genus of Ophiuroidea from various environment, play an important role in evolution. Here, we reported a complete mitochondrial genome of Amphiura sp. which was collected from a deep sea seamount in the West Pacific.
