caudal procurrent ray caudal spiny ray caudal precurrent ray caudal procurrent lepidotrichium rudimentary ray This class was sourced from an external ontology (teleost_anatomy). Its definitions, naming conventions and relationships may need to be checked for compatibility with uberon Caudal fin lepidotrichium that form part of the anterior dorsal and ventral series of lepidotrichia of the caudal fin that may be associated with a neural spine or an epural or an uroneural (dorsal series) and with a haemal spine of a preural vertebra (ventral series). Caudal procurrent rays are shorter than the caudal principal rays. A caudal procurrent ray is an unpaired median bone. UBERON:2001584 ZFA:0001584 caudal fin lepidotrichium
