| 摘 要： | 鱼类的侧线类型是由分类地位还是由环境的适应而定是进化形态学的关键问题之一。通过光镜和扫描电镜,首次描述和比较了同属鲉形目的褐菖鲉和松江鲈的侧线形态及其分布。研究结果显示,两种研究对象的侧线都仅具机械感觉系统,包括管道侧线和表面神经丘,但它们的形态及分布有差异。褐菖鲉头部管道属分枝型;松江鲈属简单型管道,比褐菖鲉有更多的表面神经丘。这两种鱼都属以管道为主,表面神经丘为辅助来感知水流动态的类型,但是,栖息在急流的褐菖鲉具有分枝型管道侧线和较少的表面神经丘分布;生活在缓流的松江鲈有简单型管道侧线和较多的表面神经丘分布,表明这些侧线的形态特征与不同栖息地水流环境关系密切。本文认为,分类地位接近的褐菖鲉和松江鲈侧线系统的形态区别,是其在进化过程中对不同栖息地水流特征的适应而形成。

| Abstract: | By using light and scanning electron microscopy, we compared the morphology and distribution patterns in two species of Scorpaeniformes: False-kelpfish(Sebastiscus marmoratus) and Roughskin sculpin (Trachidermus fasciatus). The mechanosensory lateral line system of S. marmoratus and T. fasciatus are composed of canals and superficial neuromasts. The S. marmoratus, which lives in turbulent fast flowing habitats, has a developed branching canal system and fewer superficial neuromasts. In contrast, the T. fasciatus which resides in slow flowing habitats, has a simple unbranched canal system and more superficial neuromasts. Our results show that both of the patterns mainly depend on using canal lateral line system to perceive water motion with compensate of the superficial neuromasts for sensation of accurate information from the surrounding water movement. The differences of morphological patterns of the lateral line system in two systematically close related species that reflects that adaptation to the habitat hydrodynamic environment play an important role in evolution process of morphological character formation in fish. |
