Ontogenetic development of the Weberian ossicles in the silurid catfish, Silurus asotus


Ontogenetic development of the Weberian ossicles in the silurid catfish, Silurus asotus



Journal of the Tokyo University of Fisheries 80(2): 205-211



ISSN/ISBN: 0040-9014

The development of the Weberian ossicles was described on laboratory-reared larvae and juveniles and a wild-caught young of the silurid catfish, Silurus asotus, and the origin and homology of some ossicles were discussed. No Weberian elements appeared in 7.2 mm SL and smaller larvae, and all the elements were observed at 15.0 mm SL. The elements, except for the supraneural and claustrum, derived from basidorsals 1-4 and basiventrals 3-4, and basiventrals 1 and 2 did not appear. The formation of the complex vertebra consisting of vertebrae 2-4 was traced with the larval development: vertebrae 1-4 were first observed at 9.0 mm SL as separated elements; then the vertebrae 2 and 3 fused together, and the vertebra 4 was added to form the complex vertebra', the vertebra 5 also fused, though not completely, to the complex vertebra, The neural arches of vertebrae 3 and 4 and the supraneural were fused together and then to the complex vertebra, forming a tunnel for the spinal chord. The claustrum, situated dorsally to the scaphium, seemed to originate from the supradorsal. The scaphium and intercalarium derived from the first and second basidorsals, respectively. The tripus and os suspensorium originated from basiventrals 3 and 4, respectively, and no ribs were considered to involve in their formation.
