Abstract

The snow bass Serranus chionaraia is a small-bodied reef fish presumed to be restricted to the Caribbean Province, with a single specimen captured south of the Amazon River mouth. Recent surveys with baited remote underwater stereo-video systems detected the species c. 1900 km southward. Meristic and morphometric characters of two specimens examined in this study confirmed the species identity, which greatly extends the species' range southward on the eastern coast of Brazil and indicates the presence of an established population of S. chionaraia in the Brazilian Province.

摘要

雪鲷 Serranus chionaraia 是一种小体型的珊瑚礁鱼类，据推测仅限于加勒比省，仅在亚马逊河口以南捕获到一个标本。最近使用带诱饵的远程水下立体视频系统进行的调查在该物种以南约 1900 公里处发现了该物种。本研究中检查的两个标本的可数和形态特征证实了该物种的身份，这大大扩展了该物种在巴西东海岸的分布范围，并表明在巴西省存在一个已建立的雪鲷种群。
