众所周知，鲸鲨（Rhincodon typus）会聚集在热带和亚热带水域的少数几个地方觅食。在这里，我们记录了一个新发现的鲸鲨主要聚集地，它位于阿拉伯湾卡塔尔海岸90公里外的Al Shaheen油田。鲸鲨在4月至9月期间被观察到，在5月至8月期间观察到的数量最多。据估计，在1平方公里的区域内，有多达100条鲨鱼的密度。鲨鱼的总长度估计在4至8米之间（平均6.92±1.53米）。大多数观察到的动物都积极地以海面浮游动物为食，主要包括鲭鱼、金枪鱼、鳍鱼和卵。
Whale sharks, Rhincodon typus, are known to aggregate to feed in a small number of locations in tropical and subtropical waters. Here we document a newly discovered major aggregation site for whale sharks within the Al Shaheen oil field, 90 km off the coast of Qatar in the Arabian Gulf. Whale sharks were observed between April and September, with peak numbers observed between May and August. Density estimates of up to 100 sharks within an area of 1 km2 were recorded. Sharks ranged between four and eight metres’ estimated total length (mean 6.92±1.53 m). Most animals observed were actively feeding on surface zooplankton, consisting primarily of mackerel tuna, Euthynnus affinis, eggs.
