Here the authors report on a possible range extension in the rare and understudied winghead shark (Eusphyra blochii). A specimen was captured by recreational fishermen in Moreton Bay, Queensland, Australia, c. 800 km south of its current distribution. As winghead sharks show a clumped distribution in Australia associated with river outflow, Moreton Bay, with its large catchment area, may represent a suitable habitat for the species and previous occurrence may have gone undetected. Alternatively, climate change may have caused a recent southward shift in winghead sharks, as observed in other elasmobranch species along Australia's East Coast.
在此,作者报告了珍稀且研究不足的翅头鲨(Eusphyra blochii)可能的分布范围扩展情况。澳大利亚昆士兰州莫顿湾的休闲渔民捕获了一个标本,该地点在其当前分布区域以南约800公里处。由于翅头鲨在澳大利亚呈与河流流出相关的聚集分布,集水区面积大的莫顿湾可能是该物种的适宜栖息地,之前的出现情况可能未被发现。或者,气候变化可能导致了翅头鲨最近向南迁移,就像在澳大利亚东海岸的其他软骨鱼类中观察到的那样。
