Regeneration of the caudal axial skeleton after amputation of the tail, including about 20 vertebrae is described in the gymnotoid fish E. virescens. Seven days after amputation, a regeneration blastema developed and soft tissues degenerated. A cylinder of cartilage developed at the end of the notochord. When this cartilage was about 10 mm long (21 days), perichondral ossification began. The cartilage continued to elongate and ossification increased while osteoclasts began to destory the cartilage ventrally. Finally, a bony rod formed and at its tip the cartilage persisted as a rod, 2-3 mm long. The anal fin also regenerated. Endoskeletal cartilage developed first, followed by differentiation of the lepidotrichia and ossification of the endoskeleton.
