Ossifications associated with the gill filaments of members of the Balitoridae and Cobitidae are described for the first time. Although gill-filament ossifications are common in teleosts, similar ossifications were not observed in other members of the order Cypriniformes. Their presence is interpreted as a shared and derived character uniting the families Balitoridae and Cobitidae as a monophyletic group.
首次描述了沙鳅科和条鳅科鱼类的鳃丝骨化现象。虽然鳃丝骨化在硬骨鱼类中很常见,但在鲤形目其他鱼类中并未观察到类似的骨化现象。这些骨化现象被解释为一个共享的衍生特征,将沙鳅科和条鳅科作为一个单系群联合在一起。
