Ophiurida - Wikipedia
WEBOphiurida have bursae for respiration and excretion, and dorsal and ventral arm shields are present and usually well developed. Arms are unbranched and incapable of coiling vertically. Most are five-armed, some with 4 or 6 arms as an abnormality, but others properly bear six or seven arms. The madreporite is on the oral surface.

Palaeos Invertebrates: Echinodermata: Ophiuroidea
WEBDisk and internal organs: Like all echinoderms, the Ophiuroidea possess a calcium carbonate (calcite) skeleton. In ophiuroids, the calcite ossicles are fused to form armor plates (collectively, the test). Of all echinoderms, the Ophiuroidea may have the strongest tendency toward 5-segment radial (pentaradial) symmetry.
