Evolution and Origins


Ophiuoids, and other echinoderms have adopted a secondarily-radial body plan (Mooi 2008). Evidence of the groups’ bilateral history is observed in the bilateral larvae as well as imperfect radiality due to the position of structures such as the madreporite (Mooi 2008). It has been suggested that this readoption of radial symmetry is possibly due to the sessile suspension feeder ancestory which has been hypothesised and supported by biology and paleontological resources (Guensburg & Sprinkle 2001, Nichols 1967). It is said that this ancestral form of echinoderms may carry likeness to the primitive body plan of the suspension feeding crinoids (Guensburg & Sprinkle 2001). Comprehensive literature was not found in regards to the evolution of the genus Ophioplocus.
