Definition of Term

caudal flexure

(English) The fold formed at the end of the caudal peduncle when the caudal fin is flexed to determine the position of the posterior edge of the hypural plates. This posterior edge is often difficult to determine as a point for measurement for standard length in fleshy or large fishes; some dissection may be required. (See also: standard length, caudal peduncle, caudal fin)
