南非的阿里瓦沙洲(Aliwal Shoal)是鯊鱼群集、鱼群海底成群悠游的美丽地方。全球数量最多的鯊鱼和魟鱼(rays)都在此聚首，包括锥齿鯊(ragged-toothed sharks)、沙鯊(sand sharks)和虎鯊(tiger sharks)。上百条沙鯊齐聚一堂的壮观景象前所未见，我们即将揭露牠们的祕密世界及行为模式。阿里瓦沙洲真的是观鯊的好地方：水中洞穴大得像教堂，提供避开海流的庇护所，让鯊鱼得以在此休息及养精蓄锐，并在此求偶及交配。这个位於印度洋的特殊景观点，同时也是其他形形色色小型鱼类及珊瑚温暖的家。
Off the southern coast of Africa lies an underwater metropolis like none other on the planet: Aliwal Shoal. A fossilised dune of towering pinnacles and deep caves hidden five kilometres out to sea, Aliwal Shoal is a place where sharks flock and fish walk on the bottom of the ocean.
Home to the greatest congregation of rays and sharks – including tiger sharks and ragged toothed sharks – Aliwal sees the comings and goings of thousands of migrating species. Millions of sardines are pursued to the shoal by the ocean’s great predators, with huge pods of dolphins numbering in the thousands and the shoal’s ubiquitous sharks feasting side-by-side.
Humpback whales migrate around the shoal, and cameras capture the vision of hundreds of sand sharks – never seen before – to reveal their secret world and behaviour. Evolutionary adaptations are at their most spectacular, as marine species showcase the remarkable tools Mother Nature has gifted them with to avoid predators or stalk prey.
