01------------------- The health of our oceans is under threat, and it is changing at an unprecedented rate in human history. The surface of the gorgonian is covered with a layer of mucus, which has anti-inflammatory and antibacterial effects. Tropical coral reefs only account for 0% of the total area of the seabed. 1%, but this warm, shallow water area with stable conditions throughout the year supports the most abundant and diverse biological communities in the ocean. Hogtooth is a fish that can use tools. The water in the ocean accounts for 97% of the earth's total water. The energy released by a big storm is equivalent to 10,000 nuclear bombs. Phytoplankton, seagrass and seaweed produce far more oxygen than land forests and grasslands combined. Unexpectedly, the fake killer whale and bottlenose dolphins are old acquaintances. Kelp is the largest algae in the world. After the female golden headfish reaches a certain size, it will undergo a great change in the body-becoming a male. The Gulf Stream is the largest in the world. Ocean currents carry the sun's heat from the equator to the poles, making almost every corner of the earth suitable for living things. The ocean maintains the health of our planet. The total number of glaciers in the Arctic summer is 40% less than 30 years ago. As our understanding of marine life deepens, we begin to cherish their fragile homes. The filming of the film lasted 4 years, with footprints all over the four oceans, and recorded many unknown and extraordinary stories, many of which are new scientific discoveries. In order to explore the deep sea, we spent 1,000 hours in a submersible. At sea, if the location is determined, usually you just have to wait patiently for the opportunity to arrive. 02------------------- Antarctica is the coldest, worst and most remote continent on earth. Exploring the deep ocean is as challenging as exploring space. For humans, the deepest part of the ocean is more mysterious than the surface of Mars. Surprisingly, the deepest ocean hides the most diverse life on earth. The ocean is divided into: sunshine zone, twilight zone, and midnight zone. The tube eye fish has a transparent head. The twilight zone is a refuge for 90% of the fish in the ocean. The twilight zone is the favorite hunting ground for the American giant squid. The midnight zone occupies two-thirds of the total water depth, and this dark water area is larger than the sum of other habitats in the world. Fangtooth fish have the largest teeth among fish of the same size. Although groups of jellyfish are immortal, they constantly clone themselves, and some groups eventually grow longer than blue whales. Grey sixgill sharks can stay without food for a whole year. Channeltail fish are used to swimming upright. A fallen whale is a short-lived oasis in the seabed desert. There are more coral species in the deep sea than there are in shallow tropical reefs. Some deep-sea corals can live for 4000 years. Due to human overfishing, many coral reefs that have prospered for thousands of years have been destroyed. The Mariana Trench in the Pacific Ocean is the deepest trench ever discovered, even though It is Mount Everest that will also be hidden. The animals in the Mariana Trench can withstand the water pressure equivalent to 50 jumbo jets. In this canyon 5 miles from the bottom of the sea, the lionfish is the only fish found so far. In the center of the earth's oceans, there is an underwater mountain range that spans the entire earth-the mid-ocean ridge. More than three-quarters of the volcanoes on the earth erupted on the seafloor, and almost all the volcanoes on the seafloor are located on both sides of the mid-ocean ridge. Li prawns allow bacteria colony in their mouths, but this is a very dangerous method, because Li prawns need to be washed into the hot water fountain at the risk of being cooked at any time, just to better provide food for these microorganisms. In the past ten years, the number of underwater fountains discovered has doubled. Each submarine fountain has its own independent biome. Many scientists are beginning to believe that the first life on Earth 4 billion years ago might have originated in an underwater fountain like the "Lost City". There are living things in such an extreme environment on the earth, so there must be life born somewhere far away from the earth. Photographing Antarctica is the most ambitious mission. For the first time, humans dived 1,000 meters deep in Antarctica. 03------------------- Squid is an expert in crab catching. Coral reefs cover less than one-thousandth of the seabed, but they are home to one-quarter of the known marine life. Teamwork is the foundation of life on coral reefs. There are 30,000 zooxanthellae in every cubic millimeter of coral tissue, and they co-exist mutually beneficially with coral insects. These symbiotic algae provide up to 90% of the food for coral polyps. The largest "undersea city" is the Great Barrier Reef, which spans 1,400 miles off the coast of northeastern Australia. Only the most successful marine dwellers can enjoy the extravagant time of playing games. (Such as dolphins) Sometimes hunters become prey. All clownfish families are led by a large female. The white face is a symbol of the leader. The most remote coral reef in the world is in French Polynesia, in the heart of the South Pacific. In recent years, nearly half of the world’s coral reefs have been affected by bleaching. Scientists predict that until the end of this century, the currently known coral reefs may become history. On a special night of the year, the full moon will trigger a peculiar scene-coral spawning. All the coral reefs spawn at the same time amazingly. We may not know what will be left in the future ocean, but coral reefs can regenerate. As long as the coral reef survives, hope will not be shattered. Sharks use the electroreceptors on their heads to hunt. They can tune to the weakest electricity. Stimulus, including video cameras. 04------------------- The open sea is the most expansive and barren land in the world. It occupies more than half of the earth's surface. Sperm whales are the most milk-producing mammals. It takes six years for sperm whale cubs to learn deep sea diving and independent predation. There is 1. 300 million containers span the ocean, but on average, 4 containers sink into the ocean every day. The blue shark can not eat for two months. More than half of the creatures in the deep sea follow the ocean currents. The tentacles of the Portuguese warship jellyfish can be as long as 30 meters. The Portuguese warship jellyfish can eat more than 100 small fish a day. The albatross may fly on the sea all year long. Albatross is the largest bird in existence. Approximately 8 million tons of plastic waste is dumped into the sea every year. After the plastic is decomposed, it will combine with other pollutants and then be absorbed by a large number of marine organisms. When shooting in the vast ocean, the biggest challenge is to find your target. 05------------------- The green ocean is the most fertile and highly competitive of all waters. Octopus will make shell armor to disguise itself. Macroalgae can grow up to 60 meters in length. Sea urchins will eat all the seaweed on the rocks. Sea urchins are like locusts, always swarming. Sea urchins are the favorite of sea otters. Seagrass is the only flowering plant in the sea. Green turtles feed almost entirely on seaweed. Seagrass can absorb and store 35 times the carbon dioxide of the rainforest. Australian giant squid is the largest squid. Even among giant squids, size does not always determine everything. Mysid shrimp is one of Hailong's favorite foods. Mangroves establish a natural protective barrier between land and sea, and are also the most abundant and prolific forests in the world. The zebra-striped mantis shrimp is the deadliest killer in the green ocean. After losing a partner, the female zebra-striped mantis shrimp will send out a distress signal to call for a new partner. The richer the ocean, the fiercer the competition. About 100 species of sharks live in this waters, but Craig is not deterred. For the past six years, he has been swimming here every morning. This octopus does not seem to be afraid of the camera, but will actively approach it. 06------------------- Tides make the coast the most varied of all marine habitats. The teeth of the limpet are the hardest natural substance known in the biological world, and can even be used to make body armor. Throat fish is the most viscous fish in the world, and its adhesive force is 230 times its own body weight. Chain eel is an expert in crab catching. The daily impact of waves on the coast of Nazaré is equivalent to 1.5 million tons of TNT explosives. In some parts of Europe, the coastline washed away by the waves is as long as 3 meters each year. Puffins can hold their breath for more than a minute and can dive into waters up to 40 meters deep. Rock jumping fish is the most favorite fish on earth to live on land . The penguin gave up flying and spent most of his life swimming. Two thirds of the major cities are located on the coastline. Gone are the days when coastal creatures dominated their turf. The marine iguana is the only iguana in the world that can adapt to marine life. Whenever the upwelling of the cold current stops, a large number of sea lions will be starved to death. 07------------------- The ocean is facing an unprecedented threat in human history. Whales only prey on 1% of herring, while fishermen only catch 10%. This is enough to ensure the ecological balance here. One-third of marine fisheries are being overfished. Practice has proved that as long as it is carefully managed, the fishery can be revived. Coral reefs in Southeast Asia are the most abundant in the world. The clownfish talked all day. Human noise completely changed the behavior of fish. During the filming of this film, we found plastic in every sea area, even in the most remote places. In some sea areas, there are more than one million plastic fragments per square mile. Leatherback turtles are the largest sea turtles. Fishing nets large enough to enclose the cathedral can catch hundreds of tons of fish at a time. Approximately millions of sharks are killed every year. Currently, less than 1% of our international waters are protected. In 1986, countries that depend on the sea for a living agreed to stop commercial whaling. The Great Barrier Reef is the largest coral reef ecosystem in the world. It may take an hour for the hogtooth to crack a shell. In the past three years, more than two-thirds of the world's coral reefs have been affected by the warming of the sea. The more carbon dioxide in the atmosphere, the more acidic the ocean will be. The burning of fossil fuels is the main reason for the increase in atmospheric carbon dioxide. Scientists predict that by the end of this century, sea levels will rise by one meter, or even two meters. The ocean provides us with oxygen, regulates the temperature, and provides us with food and energy. A world without a healthy ocean is unimaginable. The future of mankind, as well as all life on earth, are suspended between our thoughts at this moment. The people only capture 10%, and this is enough to ensure the ecological balance here.
