Abstract

We have analyzed our own and published data on the captures of the goblin shark Mitsukurina owstoni in the waters of Portugal and from other areas of the Eastern and Western Atlantic. Comparative morphometric analysis showed that the variability of diagnostic characteristics of specimens from different areas, including the places of capture of type specimens of nominal species, corresponds to intraspecific variability due to size and age differences. The vast majority of large mature specimens with an absolute length of more than 300 cm of both sexes were caught in the waters of the Western Atlantic. In the eastern part of the Atlantic from the Bay of Biscay to South Africa, in the catches there were mainly juvenile specimens with a length of 110 to 228 cm.

在葡萄牙海域和邻近水域捕获地精鲨鱼 Mitsukurina owstoni (Mitsukurinidae) 并评论大西洋水域物种的分类和分布

摘要

我们分析了我们自己和发表的关于在葡萄牙水域以及东大西洋和西大西洋其他地区捕获地精鲨鱼Mitsukurina owstoni的数据。比较形态计量学分析表明，来自不同地区的标本的诊断特征的变异性，包括标称物种的模式标本的捕获地点，对应于由于大小和年龄差异而导致的种内变异性。绝大多数绝对长度超过 300 厘米的两性大型成熟标本是在西大西洋水域捕获的。从比斯开湾到南非的大西洋东部，渔获物中以幼鱼为主，长110～228厘米。
