在南美洲，银汉鱼形目包括单系的齿鲨属，有20种，栖息于淡水、河口和沿海环境。阿根廷齿鱼广泛分布于大西洋的沿海和河口地区，并以闯入河流系统的河口而闻名，特别是在盐度升高的条件下。然而，据我们所知，内陆自给自足的人口从未有过记录。在这项研究中，我们检查了Salada de Pedro Luro Lake（阿根廷布宜诺斯艾利斯省东南部）的pejerrey种群，以澄清其分类身份。综合分类学分析的基础上，传统的meristic，地标为基础的形态测量学和遗传技术表明，萨拉达德佩德罗·卢罗pejerrey人口代表了一个新的情况下，生理和形态适应的海洋pejerrey物种的内陆环境，并强调环境的可塑性，这组鱼。
In South America, the order Atheriniformes includes the monophyletic genusOdontestheswith 20 species that inhabit freshwater, estuarine and coastal environments. PejerreyOdontesthes argentinensisis widely distributed in coastal and estuarine areas of the Atlantic Ocean and is known to foray into estuaries of river systems, particularly in conditions of elevated salinity. However, to our knowledge, a landlocked self‐sustaining population has never been recorded. In this study, we examined the pejerrey population of Salada de Pedro Luro Lake (south‐east of Buenos Aires Province, Argentina) to clarify its taxonomic identity. An integrative taxonomic analysis based on traditional meristic, landmark‐based morphometrics and genetic techniques suggests that the Salada de Pedro Luro pejerrey population represents a novel case of physiological and morphological adaptation of a marine pejerrey species to a landlocked environment and emphasises the environmental plasticity of this group of fishes.
