First Jurassic brittlestar from Neuquén Basin, Argentina [PDF]

open access: yesActa Palaeontologica Polonica, 2023
Articulated fossil ophiuroids from South America were reported for the Devonian, Cretaceous, Eocene, and Miocene. Here we report the first Jurassic record of an articulated ophiuroid from the Sierra Chacaicó Formation (early Pliensbachian– Sinemurian ...

A new Devonian asteroid-like ophiuroid from Spain [PDF]

open access: yesGeologica Acta, 2015
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.

New data on brittle stars (Echinodermata: Ophiuroidea) from the Persian Gulf and Oman Sea, Iran [PDF]

open access: yesIranian Journal of Animal Biosystematics, 2021
Brittle stars are one of the most diverse classes of echinoderms distributed worldwide in marine habitats. In this study, brittle stars were sampled by hand from the intertidal zone of the Persian Gulf's western part to the Oman Sea, from locations ...

Neurogenesis during Brittle Star Arm Regeneration Is Characterised by a Conserved Set of Key Developmental Genes

open access: yesBiology, 2022
Neural regeneration is very limited in humans but extremely efficient in echinoderms. The brittle star Amphiura filiformis can regenerate both components of its central nervous system as well as the peripheral system, and understanding the molecular ...

Carrion-Eating by Ophiuroids [PDF]

open access: yesNature, 1959
OPHIUTROIDS are known1,2 to eat a wide range of food, including phytoplankton, zooplankton, polychaetes and detritus; carrion-eating can now be added to the list, for it has recently been observed in this laboratory on the part of Ophiocomina nigra (Abild.), Ophiothrix fragilis(Abild.), Ophiura texturata Lam. and O. abilda Forbes.

A New Morphological Phylogeny of the Ophiuroidea (Echinodermata) Accords with Molecular Evidence and Renders Microfossils Accessible for Cladistics. [PDF]

open access: yesPLoS ONE, 2016
Ophiuroid systematics is currently in a state of upheaval, with recent molecular estimates fundamentally clashing with traditional, morphology-based classifications.

Ophiuroids (Echinodermata) of southern Chile and the Antarctic: taxonomy, biomass, diet and growth of dominant species

open access: yesScientia Marina, 1999
This study aims on a first comparison of the shallow water (< 550 m) ophiuroid fauna of the Magellan region and the high-Antarctic Weddell Sea. Five species are common to both the Magellan region (22 species) and the Weddell Sea (42 species).
