Digestive Systems: Ophiuroidea*

2020
The 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
