Blennies of the family Chaenopsidae number about 60 species of primarily tropical fishes and are particularly notable for their varied patterns of anatomical differences between males and females. This study will investigate the evolutionary relationships of 26 species within the family by analysis of these traits. This approach will address several taxonomic controversies within chaenopsids, provide a detailed study of the historical patterns of change in their sexually dimorphic traits, and, together with earlier studies on the ecology of chaenopsids, permit evaluation of alternative hypotheses for the evolution of conspicuous morphological differences between the sexes.

Chaenopsidae的数量约为60种 主要是热带鱼类，特别值得注意的是， 他们在男性和女性之间的各种解剖学差异， 女性 这项研究将探讨进化 通过分析26种植物的亲缘关系， 这些特质。 这种方法将解决几个分类 的争论，提供了一个详细的研究， 它们的性二形特征的历史变化模式， 结合之前对海鞘类生态学的研究 允许评估替代假设的演变 两性之间明显的形态差异。
