Preferred Label : caudal procurrent ray set;
Uberon definition : An anatomical cluster of short rays, shorter than the principal ones, which form the
anterior dorsal and ventral series of lepidotrichia of the caudal fin that may be
associated with neural spines, epurals and uroneurals (dorsal series) and haemal spines
of preural vertebrae (ventral series) (Arratia, 2008). The anteriormost procurrent
rays are commonly unsegmented, but the posteriormost ones are usually segmented. The
procurrent rays are numbered from caudal to rostral direction. The caudal procurrent
ray series is an unpaired median series.;
