Abstract

Otolith (sagitta) morphology is described in six tropical fish species belonged to different genera of the suborder Scorpaenoidei: Synanceia horrida, Inimicus sinensis, Parascorpaena picta, Sebastapistes cyanostigma, Scorpaenopsis papuensis, and Dendrochirus zebra. Based on otolith shape (six shape indices and elliptic Fourier analysis), S. horrida is similar to Sc. papuensis and I. sinensis is similar to D. zebra. A comparison of otolith shape in P. picta, D. zebra, and three species of the family Sebastidae (Helicolenus dactylopterus, Sebastes semicinctus, and S. hopkinsi) using elliptic Fourier and principal component analyses shows that the clusters of H. dactylopterus and S. semicinctus partly overlap with the cluster of D. zebra, and the cluster of S. hopkinsi partly overlaps with the cluster of P. picta. The data on otolith shape do not correspond with current phylogenetic schemes that indicates relative independence of the inner ear evolution.

蝎子亚目的几种鱼类种类的耳石形态及其相互关系

摘要

在属于蝎子亚目不同属的六个热带鱼物种中描述了耳石（射手座）形态：Syanceia horrida，Inimicus sinensis，Parasscorpaena picta，Sebastapistes cyanostigma，Scorpaenopsis papuensis和Dendrochirus斑马。基于耳石形状（六个形状指数和椭圆傅里叶分析），S。horrida与Sc相似。papuensis和I. sinensis与D. zebra相似。比较P. picta，D。斑马和3个Sebastidae科的耳石形状（使用椭圆傅里叶和主成分分析的Helicolenus dactylopterus，Sebastes semicinctus和S. Hopkinsi）的研究结果表明，D . ylactopteropterus和S. semicinctus的簇与D. zebra的簇有部分重叠，S. Hopkinsi的簇与。云杉的集群。耳石形状的数据与当前的系统发育方案不符，后者表明内耳进化的相对独立性。
