The lateral line system and its innervation in ten tetraodontiform families and five outgroup taxa were examined. Although some homology issues remained unresolved, tetraodontiforms were characterized by having two types (at least) of superficial neuromasts (defined by the presence or absence of supporting structures) and accessory lateral lines and neuromasts (except Molidae in which "accessory" elements were absent). The preopercular line in Tetraodontiformes was not homologous with that of typical teleosts, because the line was innervated by the opercular ramule that was newly derived from the mandibular ramus, the condition being identical to that in Lophiidae. Within Tetraodontiformes, the number of neuromasts varied between 70 and 277 in the main lines and between 0 and 52 in accessory elements. Variations were also recognized in the presence or absence of the supraorbital commissure, mandibular line, otic line, postotic line, ventral trunk line, and some lateral line nerve rami, most notably the dorsal branch of the opercular ramule, being absent in Aracanidae, Ostraciidae, Tetraodontidae, Diodontidae, and Molidae. Morphological characteristics derived from the lateral line system and its innervation provided some support for a sister relationship of tetraodontiforms with lophiiforms.
对十个鲀形目科和五个外群分类单元的侧线系统及其神经支配进行了研究。尽管一些同源性问题仍未解决，但鲀形目的特征是具有两种（至少）类型的表面神经丘（根据是否存在支持结构来定义）以及辅助侧线和神经丘（翻车鲀科除外，其中不存在“辅助”元素）。鲀形目的眶前线与典型硬骨鱼的眶前线不同源，因为该线由新从下颌支衍生而来的鳃盖支支配，这种情况与角鮟科相同。在鲀形目内部，主线上神经丘的数量在70至277个之间，辅助元素中的神经丘数量在0至52个之间。在眶上连合、下颌线、耳线、耳后线、腹侧干线以及一些侧线神经支的存在与否方面也存在差异，最显著的是鳃盖支的背支在单角鲀科、箱鲀科、鲀科、刺鲀科和翻车鲀科中不存在。源自侧线系统及其神经支配的形态特征为鲀形目与角鮟形目之间的姐妹关系提供了一些支持。
