9603896 Webb The morphology of a unique connection between the swim bladder and the mechanosensory lateral line canal system in the head of tropical coral reef butterflyfishes will be described for the first time. It is hypothesized that this unique "laterophysic" connection makes the lateral line system, which is normally only sensitive to fluid movement, sensitive to fluid movement, sensitive to pressure stimuli such as sound. 3-D reconstruction of histological material will be used to describe morphological variation in the laterophysic connection in three Chaetodon spies and to compare them with butterflyfishes in two general that lack the connection to better define the structural features that characterize this sensory specialization. Anatomical specializations in a single genus that change the function of a sensory system are rare. The laterophysic connection is an excellent system in which to study the evolutionary functional morphology of a sensory specialization. Chaetodon is a well-known and ecologically important genus of coral reef fishes for which we have an expanding body of ecological and behavioral data, and a well-supported hypothesis of phylogenetic relationships. The results of this study will lead to collaborative neuroanatomical and behavioral investigations of the function of this unique sensory specialization.

9603896 Webb首次描述了热带珊瑚礁蝴蝶鱼头部鱼鳔和机械感觉侧线管系统之间独特连接的形态。据推测，这种独特的“侧物理”连接使得通常只对流体运动敏感的侧线系统对流体运动敏感，对声音等压力刺激敏感。组织材料的三维重建将用于描述三种毛齿动物的侧物理连接的形态变化，并将它们与两种缺乏连接的蝴蝶鱼进行比较，以更好地定义表征这种感觉专门化的结构特征。一个属的解剖特化改变了感觉系统的功能是罕见的。后物理联系是研究感觉专门化的进化功能形态的一个很好的系统。毛齿动物是一种众所周知的、具有重要生态学意义的珊瑚礁鱼类属，我们有越来越多的生态学和行为学数据，并有一个很好的支持系统发育关系的假设。这项研究的结果将导致这种独特的感觉专业化功能的协作神经解剖学和行为学研究。
