Fish-Tails. — Still an-other and last example : Ithas long been noticed thatthere are amons^ fishes twost3^1es of tail-fins. These arethe even-lobed, orhomocercal(Fig. 59), and the uneven-lobed, or heterocercal (). The one is character-istic of ordinary fishes (tele-osts), the other of sharks andsome other orders. In struct-ure the difference is evenmore fundamental than in form. In the former stylethe backbone stops abruptly in a series of short, enlargedjoints, and thence sends off rays to form the tail-fin.
