Development of the pharyngeal teeth in the Chinese labeonine fish Cirrhinus molitorella

Adult pharyngeal teeth in Cirrhinus molitorella are compressed in anterior and posterior direction and formed secondary grinding surface with wear. Based on the observations of the teeth by SEM, the morphological diversification of the teeth in C.molitorella were described in this paper. The larval and juvenile teeth are changed from conical to adult teeth through seven stages. And comparisons are made between developments of the teeth in C.molitorella and Mylopharyngodon piceus, of which the development of the teeth is described in the previous paper (Nakajjima et al.).
