海底世界2【IMAX紀錄片】《海底世界》絕美的海底 千奇百怪的海洋生物 英語發音 中英字幕 1080P

Corals grow by combining carbon dioxide and sunlight But the balance of carbon dioxide in our atmosphere is critical especially to coral reefs and the creatures that call them home Every animal here depends on another in some fashion This potato cod is ready for her beautician And let's face it, when you're a cod, you need all the help you can get Cleaner fish provide a gentle service no self-respecting cod can be without While giving her a facial, the cleaners eat parasites And in exchange, the potato cod resists the temptation to gobble them up for a good deal Brown jellyfish slowly pulsate forcing tiny animals to pass through its stinging tentacles When the current carries a jellyfish into the reef butterfly fish enjoy a nibble even if it makes their little lips sting Some creatures are not satisfied with only the taste Green sea turtles love to fill their cast-iron stomachs with venomous jelly carefully closes its eyes to avoid the sting to sensitive corneas The eastern edge of the Great Barrier Reef plummets into the depths of the Coral Sea Many deep-water creatures gather on these undersea escarpments A chambered nautilus bobs its way toward deeper water Its shell contains gas-filled chambers that can withstand tremendous pressure And its primitive eye is like a pinhole in front of a light-sensitive retina Like the coral reef itself its strong shell is made of calcium carbonate Once over 2,000 species of nautiloids dominated life under the sea But that was long before dinosaurs roamed the planet And the climate above and within the ocean has changed many times since Today, only six species of nautilus haunt the deep sea Sudden changes in climate can exterminate species that cannot adapt quickly Corals need carbon dioxide to grow But we're putting so much of it into our atmosphere that it's causing global temperatures to rise If seawater gets too warm, coral reefs bleach white and die But even more death is a new threat called ocean acidification Too much carbon dioxide inhibits the formation of calcium carbonate The stuff coral reefs are made of and the shells of the chambered nautilus the cuttlebone and the skeletons of thousands of other species Many animals could become extinct Coral reefs could begin to dissolve As temperatures rise many species can move south toward cooler waters The dwarf minke whale spends its winter on the Great Barrier Reef Then in the spring, it heads south to the cold waters of the southern ocean Cape Catastrophe, South Australia In these cold waters lurks an ancient leviathan one of the ocean's most magnificent hunters The great white shark Great whites often reach 17 feet in length A shark that large may weigh more than a ton and can easily make a single meal out of a 200-pound sea lion Sea lions must remain constantly alert The world's largest stingrays also hunt here searching for crustaceans and molluscs hiding beneath the sand The rays often travel with their own entourage a squadron of opportunistic fish ready to pounce on small animals frightened from their hiding places Most of the time, the great white shark will ignore a stingray, but not always Great whites have often been found with foot-long stingray barbs embedded in their jaws Australian sea lions are among the rarest of marine mammals Once hunted relentlessly, now only 10,000 or so remain They seem to be the most carefree of creatures But as global temperatures rise, the animals living in South Australia have nowhere further south Each year in these shallow gardens, giant cuttlefish gather for spawning They are the largest cuttlefish in the world Males sometimes reach more than 3 feet in length Giant males confront each other, competing for females, hiding in the yellow sponge below These confrontations seldom result in serious violence Instead, males puff themselves up and look as menacing as possible Then communicate their willingness to fight with angry displays of color and pattern As the big males compete, smaller males, called sneakers, disguise themselves as females Then cloaked in feminine charm, they slip past the dueling giants unchallenged Females seem to find the cross-dressing males quite attractive Sneakers are surprisingly successful lovers Giant cuttlefish mate face to face in a tangled embrace that may last many minutes The urge to find a mate is strong, but this cuttlefish is hungry The crab's sharp claws cause the cuttlefish to hesitate No one likes to be pinched in the face, but a crab dinner certainly seems worth it A female has deposited her eggs in a crevice beneath the reef This is her final act In the next few weeks, all of the adult male and female cuttlefish will die Giant cuttlefish live only two years, but these have left their legacy In about four months, these eggs will hatch and a new generation of giants will inherit this undersea garden Swarms of mycid shrimp roll over the reef like a mountain fog These tiny shrimp become food for many species One is among the most bizarre of all ocean creatures The weedy sea dragon is one of only three species of sea dragon that exist on earth He propels himself by undulating tiny transparent fins on his back and on either side of his head The dragon slurps his dinner with a long tubular snout that's perfectly designed for capturing tiny shrimp The other dragon living here defies even the most fertile imagination The leafy sea dragon He has turned camouflage into an exquisite work of art Sea dragons seldom venture far from home Indeed,these delicate creatures are not designed to swim fast or far As the climate changes, undersea gardens in the gulfs of South Australia are beginning to die out When these gardens dissipate, the dragons must vanish with them But there are hopeful signs of an even greater change taking place It's a change within us We finally seem ready to accept the responsibility for the changes we are causing to our atmosphere, our oceans, and our planet We have the skills If we apply them, our legacy could be an ocean wonderland where dragons still roam and where sea lions are forever at play 優優獨播劇場——YoYo Television Series Exclusive
