Finding Nemo in New Caledonia
新喀里多尼亚

There's this colony of clownfish that lives just on the crest of the fringing reef at Mato. Two species of clownfish (also called anemonefish), each with their respective species of anemone live practically (but not quite) on top of each other. Amphiprion melanopus is the bright orange anemone fish and Amphiprion clarkii is the very dark orange clownfish with two vertical blue-white stripes. Clarkii gets chummy with about 10 different species of anemones but Melanopus is partial to the bubble tip anemone Entacmaea quadricolor - but will pair up with a couple of other species in some areas. You can see the brown bubble tipped anemone tentacles amidst the coral branches on the Melanopus side of the sphere. 

The usual photos of clownfish show them nestled down into the tentacles of their partner anemone, and there is a lot written about their intimate relationship with their anemone partners. But actually these colorful little fish are normally out swimming around, nibbling on plankton or sometimes on algae and generally having a good time on the reef. But when a human comes by they make a dive for the protection of the sea anemone. They also tuck into their anemone at night to sleep.

To take this sphere image showing how the anemone fish behave when nobody is around to bug them, I set up my underwater robot camera between the two colonies of clownfish. It was so calm that you can see the reflection of the surrounding reef on the mirror-like surface. The front of the camera dome was only about 4 cm from the surrounding coral on each side and about 20cm from the blue coral on the bottom. As I set up the camera every single anemone fish (and in fact all the pretty tropical fish) were hiding. Most of the fish, even the little tropicals, took off the instant Freddy and I approached. We believe this is because the aquarium trade is pretty active in Noumea and collectors - both private and commercial - harass the little tropical fish on the reefs even in remote places like Ilot Mato. So they have a good reason to make themselves scarce when they see a human approaching. Nemo has learned his lesson in the New Caledonia lagoon.

While getting everything ready I thought about the fact that these little guys might be as much as 10 years old, maybe older, so they have seen a lot of people - and collectors - during their lives. I also thought about the fact that their life spans in aquaria are a lot less than that - sometimes only a week or two in a poorly maintained aquarium. Even the ones bred in captivity only live half the life expectancy of the wild fish. I have to say, I don't like the idea of capturing little fish because they are beautiful and selling them to people who may or may not be able to keep them alive.

Freddy and I swam off and let the camera and the clownfish get to know each other. The famous Aquarium in Anse Vata - the old one set up as a marine laboratory by Rene Catala back in 1953 - was an exception to my general dislike of aquaria. Rene was a biologist and the aquarium he created was phenomenal - undoubtedly the very best marine aquarium I had ever seen. His goal was to create miniature habitats in the laboratory so he could closely study and photograph the behavior of the marvelous sea creatures of New Caledonia. Nowhere else had aquaria been able to keep corals alive and growing - they even settled naturally on the aquarium walls and grew there! That alone was a key indication of the biologically tuned ecosystems he created. He was a dedicated, talented, and concerned scientist and - almost magically - the sea creatures thrived in his care.

The old aquarium is gone - turned over to the city of Noumea back in 1975 and now reincarnated as a much larger, architectural masterpiece, filled with dying creatures - constantly replaced by divers - and plagued with the usual sorts of technical and biological difficulties that infect aquaria large and small around the world. Difficulties that make professional fish and coral collectors happy and rich. Difficulties that make the smallest of tropical fish on the coral reefs of New Caledonia dive for cover whenever they see a human coming. Except - I should add - in the excellent New Caledonian marine reserves where there is absolutely no collecting allowed. Like Ile aux Canard, Ilot Maitre, and Ilot Amedee. There, you will actually be surrounded by tropical fish while you snorkel. Proving my point that the stark terror exhibited by fish of every size and description - even sharks - when they see a human in the water is justified by ongoing human attacks.

As we returned to the robot camera I hovered just on the edge of visibility and could see the little clownfish clowning around, even peering into the camera case. Now, here on 360Cities.net, you have a chance to see them face to face - and they are still (I hope) safe and snug in their little anemones surrounded by their mates at Ilot Mato.

Oh, and don't forget to find the live cowrie shell in this underwater sphere image.

More About 新喀里多尼亚

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。
