A school of anchovies swarms together, forming a scintillating mass attacked from above and below in a fascinating example of interspecies hunting. This happens every day in New Caledonia's vast coral reef lagoon.
Predatory fish must identify a particular fish to catch it. The anchovies create a speeding vortex of thousands of individual fish moving in perfect unison so the predators can't single one out. But these huge jacks knew exactly what to do. They coordinated their attacks, some of them coming up from below while others peeled the anchovies away from the ball, right into the path of the ascending fish that would burst right out of the water with a fountain of glittering anchovies all around them. In the mayhem the anchovies would scatter, making perfect targets for the predatory fish and for the birds.
Red billed sea gulls (Larus novaehollandie) understand the strategy. They flew right above the jacks that were striking in from the side so the birds were in exactly the right spot to feast on the fountain of anchovies when the big jacks came bursting up from the depths. The gulls sometimes snatched anchovies right out of the mouths of the striking fish - then leaped back into the air, often tossing their catch into the air and then gulping it down.
After about 20 minutes of this mayhem it got really wild. Other species of fish joined in, barracuda, mackerel, snappers. A school of sharks swam around the whole group, moving in closer and closer, maybe picking up titbits of hashed sardines. More birds came from every direction, flocks of Noddy turns (Anous tenuirostris), stayed maybe 20 to 50 metres away from the centre of the feeding frenzy. A few of the tiny, white " Black Naped Turns", (Sterna sumatranta), circled around but they, like the noddy turns, stayed away from the centre of the intensive feeding frenzy. Possibly because the sea gulls might get aggressive if the smaller turns got in their way and would certainly try to steal any fish the smaller birds caught. You can see in the sphere image that when one sea gull caught a fish and didn't get the fish down the gullet fast enough, the other sea gulls made serious tries at stealing it.
This is fishing in the extreme, with continuous action that goes on for up to three hours with a bewildering array of species harvesting the small but abundant schools of "bait" fish.
新喀里多尼亚是离澳大利亚和新西兰最近的南太平洋岛屿。该岛是法国领地且官方语言是法语，尽管如此，其文化却丰富多彩，揉合了美拉尼西亚、欧洲、波利尼西亚、越南、中国、印尼等国的风情。这里有一个多山的大岛，称为大地岛 (Grande Terre)，和6个较小的岛屿——洛亚蒂三岛 (Loyalty Islands)、贝莱普群岛 (Belep) 和松树岛 (Isle of Pines)。 整个群岛人口极为稀少，有大片的荒野。这里有数百公里长的徒步小径、随处可见的露营营地、超过42个公园和保护区、清澈透明的河流和莹莹闪光的瀑布。约三分之一的人口居住在首府努美阿。镍的开采是该国最主要的工业，也是维持其高标准生活的主要经济来源。大地岛四周环绕着世界第二大珊瑚礁，此珊瑚礁形成的泻湖是世界上最大的，也是受保护的泻湖。该泻湖于2008年被列为世界遗产，面积达24000平方公里，是品种丰富的鱼类和无脊椎动物栖息之地。 对于刚上岛的游客而言，最引人注目的是这里鲜艳夺目的色彩。努美阿以其完备的酒店、度假酒店、餐馆设施和丰富多彩的活动欢迎游客的到来。
