Identifying cryptic species and juveniles in the Ophiuroidea has always been a challenge. However, post-larval developmental studies have the potential to uncover the identity of these cryptic species and juveniles, as they offer valuable information ...

The class Ophiuroidea, despite having a wide distribution on the coast of Brazil, only 150 species have been described, which highlights the need to increase the number of regions/areas sampled from a more detailed perspective of their morphology.

The brittle star samples collected by the Danish cruise 'Galathea II' (1950-52) had not been studied completely. We examined the remaining deep-sea samples (400 m) and present the species inventory, discussing taxonomic issues in relation to recent ...

Gorgonocephalus eucnemis (Echinodermata: Ophiuroidea) and Bursal Ventilation
The Biological Bulletin, 2020The basket star Gorgonocephalus eucnemis is an aerobic organism highly dependent on dissolved oxygen in surrounding waters. Previous observations on the anatomy of Gorgonocephalus state that five pairs of ossicles (the radial shields and genital plates) regulate the position of the roof of the body disc and are responsible for flushing seawater into ...

Journal of morphology, 2021
Studies on size changes of Ophiuroidea are limited, despite their importance and implications in taxonomy, phylogenetics, ecology, and distribution. These studies have traditionally been based on descriptive size series seldom integrating quantitative ...

Digestive Systems: Ophiuroidea*
2020The digestive system of ophiuroids is undoubtedly the simplest among echinoderms. Ophiuroids have blind guts with the mouth always situated mid-ventrally and more or less hidden by a jaw apparatus located just below. Published data pertain mainly to species belonging to the order Ophiurida. The stomach consists of a relatively flat central area and ten

Class OPHIUROIDEA Gray, 1840 Order incertae sedis REMARK Apomorphies and additional morphological characteristics used to assign Componaster n. gen. to the Ophiuroidea are summarized in Blake (2013, 2014), and amended and/or discussed in Blake & Guensburg (2015), Blake et al. (2017) and Blake & Nestell (2019).
