Despite their large size, with wingspans stretching up to 12 feet (3.6 meters), as many as 200 mantas may pack a football field-sized bay during these feeding frenzies.
尽管它们体型巨大，光是翼幅展开就宽达3.6米，但在这种狼吞虎咽的关键时刻，一块只有足球场大的海湾区域还是有多达200只的蝠鲼挤在一起。
Mantas, with their slow reproductive rate, are vulnerable to overfishing, so a robust tourist trade could give local communities an economic incentive to conserve the fish rather than kill them.
蝠鲼繁殖率缓慢，很容易受到过度捕捞，所以强大的旅游业可以给当地社区的经济补助，以保护鱼类，而不是杀死它们。
