Ocean Wonderland (2003)
Here is where I live.
Well, not right here. I move around all the time, visiting my many friends, keeping an eye on the situation. I've been doing it for years and years. And as you can see, I am far from alone down here. Sometimes it gets crowded. The ocean is home to countless variations of sea life. My grandfather used to say, "Even the camels wandering the Sahara, "even the mountain goats high up in the Alps are creatures of the oceans, "for they too depend on the oceans for their survival. "Without healthy oceans no life, not even on land, can exist. " He'd say that every time he was upset with the way mankind was treating our home. Now that I am older and wiser, I'm starting to understand what he meant. And that good-looking fellow there, well, that's me. If you'd like to tag along, I'll show you around. If you come from the inland, your first encounter with the ocean is unforgettable. If you've ever crossed an ocean, its vastness, its power and serenity are overwhelming. But only when you've dived beneath the waves does the miracle of the ocean and all its beauty truly reveal itself. The ocean wonderland. Here, and all around the tropics, is the pulsating heart of the oceans, the coral reefs. Now I could go on and on and tell you all about each and every one of the 800 known species of reef-building corals, where each coral is a tiny colony of sea life, or about the incredible diversity of shapes and sizes. I could even tell you that a small coral table, like this one, is the home to, oh, about 300,000 inhabitants. But I won't. Too dry. Boring. Okay, but here's a question for you. What is coral? Is it plant or rock? It's a trick question. It's neither. It's an animal. Imagine thousands and thousands of tiny creatures clustering together, and sharing a common skeleton made of limestone. That's what coral reef is. Skeletons built upon skeletons, until big, well, sometimes absolutely huge structures are formed, like here, the Great Barrier Reef in Australia, which is so enormous it can be seen from space. Well, that's what they tell me. I've never been. Like me, corals are sensitive creatures. They thrive only in clear, warm waters with lots of sunlight filtering through. Coral is fragile and it grows ever so slowly. So, if some klutz breaks off a branch of this staghorn coral, it would take many years for it to grow back. Something to think about next time you're tempted to break off a little souvenir. Big boulder corals seem to live forever. This one is over 500 years old. Grandfather told me that our family has been swimming on the reefs for ages, over 100 million years, actually. The nooks and crannies, the complex structure of the reef is something that appeals to a vast number of species. There are over 4,500 different types of fish on the reefs. They make the reef their home and playground and also their battleground. The batfish, curious and gentle wanderers in and around the reef. These are pompano, rather well-behaved during the day, but predators by night. With their bright colours and their beak-like jaws, it's no wonder they're called parrot fish. The giant Napoleon wrasse is a fabulous character, reaching a weight of 400 pounds, always inquisitive, always with an eye on the next meal. Puffer fish, about as fast a swimmer as poor cousin Quincy, are protected by a poisonous flesh. Like their name indicates, they can puff themselves up with water when they feel threatened. They become bigger and scarier-looking and not quite as easy to fit between your jaws. Look closely. No, closer. Can you spot the trumpetfish hiding amongst these whip corals? Shipwrecks, like this one in the Bahamas, are mighty popular down here. In many ways, they replicate the complex structure of coral reef and quickly become home to sea life, as well. Here, the fish can rest, hide or wait in ambush. Beautifully coloured queen angelfish together with a pair of delicate butterflyfish has moved in and made a home amongst the fan corals growing on the wreck. With so many different species, the competition for space and lunch can be fierce. Struggle and swim, struggle and swim, but never a dull moment! The strangest alliances have evolved between species in order to survive. Sea anemones are animals that live attached to the reef. They capture small fish and kill them with stinging tentacles. The clown fish, however, is a crafty little fellow who has evolved a technique which fools the anemones, and therefore can move freely amongst the tentacles. The giant reef anemones become their safe haven. As you may know, I can't stay down here forever. I must surface for air once in a while, just like the next creature we're about to meet, the dolphin. Actually, they bear quite a few similarities with us turtles. Intelligence, beauty, style, grace. Okay, maybe they do get around a bit faster than us. Dolphins have fascinated humans since time immemorial. An encounter with one is always a magical moment and a memory for life. Hey, how often do you get the chance to touch a wild dolphin. So go on, give it a go! Showing off his dance moves again. Reminds me of myself in younger days, actually. Now, Grandfather, who claimed that camels were sea creatures, certainly enjoyed his metaphors. He compared the endless waters of an ocean to the endless sands of a desert, and the coral reef to an oasis. The reefs are havens where sea life abounds and all the different species depend on each other for survival. Huge schools of yellow snappers thrive on parts of the reef. Let me introduce you to this wonderful ballet my friends have prepared for you. Well, you wouldn't get a bunch of turtles to carry on like that, but it's rather fascinating, don't you think? Thank you, my friends. See you later. Now, no one particularly likes becoming someone else's lunch, but down here, we're pretty realistic about our place in the food chain. You eat and you are eaten. That's just the way it goes. These sandy plains may seem barren to you, but just below the surface live countless molluscs and small worms. And any creature with the right appetite, and the right technique knows they are down there. Stingrays are experts at finding and excavating their prey from the sand. Their mouth is under their body, while their eyes are on top. To me, this is a little strange. They have powerful jaws, of course. Not as strong as mine, but they are capable of crushing even the hardest shells. And as always, nothing goes to waste. The smaller fish feast on the scraps the larger ones leave behind. When I think of life on the reef, two things come to mind, abundance and extraordinary diversity. These are surgeonfish. They graze on the algae growing on the rocks. They find safety in numbers and confuse their predators by travelling together. Traffic can get heavy at times. It's okay, I can wait. Bigeye trevallies are another sociable species, at least by day. By night, the dense schools disperse and each fish must find its own dinner. Although the barracuda exudes elegance and danger, unless provoked, they are no danger to you humans. With nightfall, a strange serenity descends on the reef and a whole new array of life is revealed. Many creatures filter the water for food, like these feather stars. The corals themselves extend their tentacles to catch zooplankton. Sea squirts filter the waters in search of nutrition. Small fish retreat into the delicate maze of coral branches. At night, these trumpetfish prefer the man-made shelter the shipwreck can provide. This puffer fish doesn't look too happy about our late-night intrusion, so let's sneak away. Come on. Sorry, my friend. Go back to sleep. Here's a creature that always makes me duck into my shell, one of the deadliest on the planet, the sea snake. Let's follow it into deeper water, where the colours begin to fade away. It moves through the water like a ribbon of doom, with a venom so powerful that just one bite is all it takes. You're dead within seconds. I think I'd rather wait up here. Could we get moving? Everyone still with us? Good. Luckily for you, sea snakes seem to prefer seafood. They rarely attack humans. Here is one of the most important predators to be found on a reef, the potato grouper. Some groupers reach truly impressive sizes, over 8-feet long and weighing more than 600 pounds. They don't skimp on their meals, either. The largest ones even dine on small sharks and, sadly, young turtles. Yes, poor Quincy ended his days as a rather unhappy meal for a potato grouper. When two groupers meet for combat or courtship, complex rituals often ensue. Hard to believe and hard to admit, but the ocean's most graceful creature is not the turtle. It's the eagle ray. As these gentle giants glide along with the majesty of their airborne namesakes, it is easy to forget that we are viewing fish beneath the waves and not eagles above the clouds. Their wingspan can reach widths of up to 8 feet. Even in these murky waters, the eagle ray is an elusive beauty. An encounter with even just one is always a privileged moment. Sometimes I wish I had wings like those. But then again, I make out fine just the way I am. Diving deeper, you'll meet lurking among the reefs the most powerful predator of them all. The shark is among the ocean's most ancient inhabitants and, for me, the scariest, I might add. So if you don't mind, I'll stay here while you look at them. 350 million years of evolution have honed them to predatory perfection. Hundreds can find their home in one healthy reef. Fast, fierce, sleek and agile, an incredible animal that I prefer to view from afar, because at feeding time, they behave as if they have a licence to kill. And I suppose they do. Unprovoked, sharks rarely attack people, and yet humans have decimated the shark population by killing millions of them each year. Sharks are now rare on most reefs. Today, another darker reality faces our reefs. They are endangered. When a coral reef dies, all the life that thrives in and around it vanishes, as well. Since one-quarter of all us marine life depends on the reef for survival, imagine the consequences. The health of the planet depends on the health of its oceans. When oceans sicken and die, the well-being of our Earth is thrown into peril. I used to visit this reef every year when I was younger, a reef that was teeming with life and activity. Today, this reef is dead. There is no more life here. Sewage, industrial waste, pollution, destructive fishing practices, careless tourism and even deforestation are some of the man-made elements that threaten the health of our reefs. In addition, the massive energy consumption of humans is altering the planet's climate and warming up the oceans. One silent victim is the coral. If human activity continues on its present course, most of the world's coral reefs may be dead within 50 years. The problem is clear. And many of the solutions are already known. Modern man must transform himself from being the threat to becoming the defender. Around the globe, many organisations, such as the United Nations Environment Programme and the World Wildlife Fund, are already working hard to improve the health of our oceans. Together, you can ensure a brighter future for coral reefs and the millions of other creatures that live beneath the waves. For yourselves and future generations, please help save the coral reefs and preserve this ocean wonderland. |
