Frequency of sublethal injury in a deepwater ophiuroid, Ophiacantha bidentata, an important component of western Atlantic Lophelia reef communities [PDF]

, 2007
The occurrence and relative abundance of tissue (arm) regeneration in the ophiuroid, Ophiacantha bidentata (Retzius), was examined in individuals collected primarily among colonies of the deep-water coral Lophelia pertusa off the southeastern United ...

Brittle stars from the British Oxford Clay: unexpected ophiuroid diversity on Jurassic sublittoral mud bottoms

, 2017
Three new ophiuran species, Enakomusium whymanae n. sp., Aspidophiura? seren n. sp., and Ophiotitanos smithi n. sp., and an unnamed specimen assignable to the genus Dermocoma are described from the Callovian to Oxfordian Oxford Clay Formation of Great ...

A remarkable example of a Late Jurassic shallow-water ophiuroid assemblage from the Swiss Jura Mountains

, 2013
Although much effort has been put into attempts to unravel the Mesozoic ophiuroid fossil record, surprisingly little attention has been paid to the geological history of family-level compositions of brittle star assemblages.

A new Devonian asteroid-like ophiuroid from Spain

, 2021
A Lochkovian (Early Devonian) ophiuroid (Echinodermata), Ophiocantabria elegans n. gen. and sp., is based on a single small, well-preserved specimen collected from a shale-rich horizon of the Furada Formation, Asturias, Spain.

Maintain the light, long-term seasonal monitoring of luminous capabilities in the brittle star Amphiura filiformis

Scientific Reports
The European brittle star Amphiura filiformis emits blue light, via a Renilla-like luciferase, which depends on the dietary acquisition of coelenterazine.

Evo‐devo in the ophiuroid family Ophiocomidae

Invertebrate Biology
AbstractThe Ophiuroidea, the most diverse echinoderm class, exhibits an array of life history patterns and larval forms, the evolution of which is poorly understood. With a robust phylogeny available for the major family, the Ophiocomidae, we undertook an assessment of the evolution of development in these ophiuroids.

Two new steroidal glycoside sulfates, longicaudoside-A and B, from the Mediterranean ophiuroid Ophioderma longicaudum

, 1986
Longicaudoside-A (I) and -B (II), 2 new steroid glycoside sulfates, were isolated from O. longicaudum by HPLC, and their structures were elucidated by a combination of 1H- and 13C-NMR, fast-atom bombardment mass spectroscopy, and chem. degrdn. These are
