Fishery-dependent and -independent data collected since 1975 were examined to explore the spatial distribution of 30 shark and ray species in the west coast of Australia. Bigeye sixgill (Hexanchus nakamurai), tiger (Galeocerdo cuvier) and spinner (Carcarhinus brevipinna) sharks, and scalloped hammerhead (Sphyrna lewini) were observed >1000 and 300 km to the east of the edge of their reported distributions. Broadnose sevengill sharks (Notorhyncus cepedianus) and southern sawsharks (Pristiophorus nudipinnis) were observed >1000 km to the west of the edge of their reported distributions. Our study highlights the value of collecting and examining long time-series of data for understanding the spatial distribution of large marine predators.
自 1975 年以来收集的渔业相关和非渔业相关数据被用来探讨澳大利亚西海岸 30 种鲨鱼和鳐鱼的空间分布。大眼六鳃鲨（Hexanchus nakamurai）、虎鲨（Galeocerdo cuvier）和尖嘴魟（Carcarhinus brevipinna）鲨鱼以及波纹齿锤头鲨（Sphyrna lewini）在报道分布范围的东部超过 1000 和 300 公里处被观察到。宽鼻六鳃鲨（Notorhyncus cepedianus）和南非锯鳐（Pristiophorus nudipinnis）在报道分布范围的西部超过 1000 公里处被观察到。我们的研究强调了收集和检查长时间序列数据以了解大型海洋捕食者的空间分布的价值。
