本文综述了硬骨鱼类机械感受侧线系统的形态和发育，总结了确定类型侧线系统的系统分布。强调了解个体发育的重要性，并讨论了系统发育和发育限制在侧线系统进化中的作用。四种类型的头管系统确定的基础上的相对发展的运河和方向的神经肥大受体包含在其中。这些模式的分布在四个主要的硬骨鱼类分支进行了分析。有人建议，一个分支的小管系统与头运河是一个原始的硬骨鱼字符，而扩大和减少头运河的模式是收敛的功能专业化在许多类群。主干管包含在一个连续的系列侧线规模，和八个主干管模式描述硬骨鱼。鉴于不同干渠格局的系统分布、生态习惯和体型的相关性，干渠似乎可以作为游动鱼类的水动力监测器。
The morphology and development of the mechanoreceptive lateral-line system in teleost fishes is reviewed, and the systematic distribution of defined types of lateral-line systems is summarized. The importance of an understanding of ontogeny is stressed and the roles of phylogenetic and developmental constraints in the evolution of the lateral-line system are discussed. Four types of head canal systems are identified on the basis of the relative development of the canals and the orientation of the neuromast receptors contained within them. The distribution of these patterns in the four major teleost clades is analyzed. It is suggested that a branched tubule system associated with the head canals is a primitive teleost character, while widened and reduced head canal patterns are convergent functional specializations in many taxa. The trunk canals are contained in a continuous series of lateral-line scales, and eight trunk canal patterns are described in teleosts. Given the correlation of the systematic distribution of the different trunk canal patterns, ecological habit and body shape, it appears that the trunk canals may function as a hydrodynamic monitor in swimming fishes.
