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.

Twinkle twinkle brittle star: the draft genome of Ophioderma brevispinum (Echinodermata: Ophiuroidea) as a resource for regeneration research

BMC Genomics, 2022
Echinoderms are established models in experimental and developmental biology, however genomic resources are still lacking for many species. Here, we present the draft genome of Ophioderma brevispinum, an emerging model organism in the field of ...
