Gorgonocephalus eucnemis (Echinodermata: Ophiuroidea) and Bursal Ventilation

The Biological Bulletin, 2020
The 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 ...

Regeneration in Stellate Echinoderms: Crinoidea, Asteroidea and Ophiuroidea

2018
Reparative regeneration is defined as the replacement of lost adult body parts and is a phenomenon widespread yet highly variable among animals. This raises the question of which key cellular and molecular mechanisms have to be implemented in order to efficiently and correctly replace entire body parts in any animal. To address this question, different
