Scanning electron microscopy and standard histological techniques were used to describe the basic anatomy and postembryonic growth of the lateral line system of Cottus bairdi. The gross anatomy and distribution of lateral line neuromasts in canals and superficially on the skin are similar to what has been reported for many primitive actinopterygian fishes. Both canal and superficial neuromasts showed postembryonic growth in the number of hair cells and size of neuromasts, but canal neuromasts grew more elongate whereas superficial neuromast grew symmetrically. Neuromasts in the mandibular canal grew significantly faster than any other neuromasts and superficial neuromasts on the head showed the least amount of growth. Differential growth of the sculpin lateral line system may be related to the feeding behavior of the animal and to differences in the ambient levels of water noise to which larval and adult fish are exposed.
利用扫描电子显微镜和标准组织学技术描述了贝氏杜父鱼侧线系统的基本解剖结构和胚后生长情况。侧线神经丘在管道内和皮肤表面的大体解剖结构及分布与许多原始辐鳍鱼类的报道相似。管道神经丘和表面神经丘在毛细胞数量和神经丘大小方面均呈现胚后生长，但管道神经丘变得更细长，而表面神经丘呈对称生长。下颌管中的神经丘生长速度明显快于其他任何神经丘，头部的表面神经丘生长量最少。杜父鱼侧线系统的差异生长可能与动物的摄食行为以及幼鱼和成鱼所接触的环境水噪声水平差异有关。
