Abstract

Little is known about the ecology and distribution of mobulid rays along Brazil's extensive coastline. Here we report opportunistic sightings of manta rays (Mobula cf. birostris) in the Brazilian Amazon estuaries and the Great Amazon Reef System. These sightings consist of manta ray individuals stranded in tide pools, caught in artisanal fisheries, and footage obtained with a submersible. Future investigations on the spatial, temporal, and environmental drivers of manta rays' distribution on the northern Brazilian coast and the threats posed by fishing gear are warranted.

摘要

关于巴西广阔海岸线的蝠鲼生态和分布，人们知之甚少。在这里，我们报告了在巴西亚马逊河口和大亚马逊珊瑚礁系统中偶然发现的蝠鲼（Mobula cf. birostris）。这些目击事件包括被困在潮水池中的蝠鲼个体、被手工渔业捕获的个体以及潜水器拍摄到的影像。未来有必要对北巴西北部海岸蝠鲼分布的空间、时间和环境驱动因素以及渔具造成的威胁进行调查。
