Taxonomy, biodiversity and biogeography of the brittle stars (Echinodermata: Ophiuroidea) of South Africa
The South African Ophiuroidea were last reviewed by Clark and Courtman-Stock in 1976. In the current investigation, the systematics of the group is thus revised in its entirety for the first time in 40 years. The data used originated from a number of sources. Existing data were sourced from i) …

Faunal biogeography, community structure, and genetic connectivity of North Atlantic seamounts
… utilized as a genetic "barcode" within the Class Ophiuroidea, through which 22 putative species were identified, including four target species (Asteroschema clavigera, Ophiocreas oedipus, Ophioplinthaca abyssalis, and Ophioplinthaca chelys) for subsequent population genetic studies. Analyses of …

Elucidating the evolution and diversity of the Southern Ocean ophiuroids with reference to present day ecosystem management
… of Southern Ocean<br/>brittle stars (Class Ophiuroidea), based on two exemplar species, Amphiura<br/>belgicae and Ophioplinthus gelida, both common across the Southern Ocean<br/>shelf regions, that have been sampled over several expeditions across a wide<br/>spatial scale. Mitochondrial DNA …

Post-larval development in deep-sea echinoderms
… echinoderms, belonging to three classes (Ophiuroidea, Asteroidea and Echinoidea), is described using scanning electron microscopy. The life history of Ophiocten gracilis is also examined as a case study for future research on post-larval organisms. The analysis of development in ophiuroids …
