Taxonomic revision and phylogeny of the Ophiocoma brevipes group (Echinodermata, Ophiuroidea) : with description of a new subgenus (Breviturma) and a new species [PDF]
, 2013 The taxonomy of the genus Ophiocoma was last revised by Devaney in 1970. Recent discoveries of new species and re-instatement of previously synonymized names suggest that we still do not fully understand the species limits in this genus.

An exon-capture system for the entire class Ophiuroidea [PDF]
Molecular Biology and Evolution, 2015 A BSTRACT We present an exon-capture system for an entire class of marine invertebrates, the Ophiuroidea, built upon a phylogenetically diverse transcriptome foundation. The system captures ~90 percent of the 1552 exon target, across all major lineages of the quarter-billion year old

Ophionereis reticulata (Echinodermata, Ophiuroidea) [PDF]
Iheringia. Série Zoologia, 2010 This study compared the arm regeneration frequencies in two different populations of Ophionereis reticulata (Say, 1825) in São Sebastião, Southeast Brazil and observed arm regeneration between age classes (juvenile and adults) and sexes (male and female). From the 1,170 individuals sampled, 1,089 (92.2%) showed signs of arm regeneration.

Sequencing and analysis of the gastrula transcriptome of the brittle star Ophiocoma wendtii [PDF]
, 2012 Background The gastrula stage represents the point in development at which the three primary germ layers diverge. At this point the gene regulatory networks that specify the germ layers are established and the genes that define the differentiated states ...

Mitochondrial genomes resolve phylogenetic conflicts and lineage-specific adaptive dynamics in Ophiuroidea: insights from deep-sea lineages [PDF]
Zoosystematics and EvolutionOphiuroidea, the most diverse class of echinoderms, occupy habitats ranging from coastal zones to deep sea, offering unique insights into evolutionary adaptation and biogeography. Despite their ecological prominence, the phylogenetic relationships within
