摘要

提供了从搁浅在智利科昆博地区瓜纳奎罗斯海岸（30°s）的灰喙鲸（Mesoplodon grayi）的完整雌性幼年个体身上收集的信息。基于诊断表型特征的使用，如颜色模式和下颚牙齿位置的差异，讨论了区分格雷喙鲸和赫克托喙鲸标本的困难。对头骨特征和分子分析的详细审查支持了将研究标本鉴定为格雷喙鲸。最后，我们提供了一份最新的清单，其中包含了该物种在智利的所有已知记录。

Review of Gray's beaked whale (Mesoplodon grayi) in the South East Pacific

Information collected from a complete female juvenile individual of Gray's beaked whale (Mesoplodon grayi) stranded on the Guanaqueros coast, Coquimbo Region in Chile (30°S) is provided. Difficulties to differentiate specimens of Gray's beaked whale and Hector’s beaked whale (M. hectori) are discussed based on the use of diagnostic phenotypic characters, such as differences in color patterns and position of teeth on the lower jaw. The identification of the studied specimen as Gray's beaked whale was supported by a detailed review of cranial characters and molecular analyses. Finally, we provide an updated list containing all known Chilean records for this species.
