The blue whale, being the largest animal in the ocean, has a tongue as heavy as an elephant, some veins so wide that we can swim through them, and a tail fin as wide as the wing of a small plane, but it lives on krill, one of the smallest creatures in the ocean. A blue whale can eat millions of krill in a single day.
The krill will gather in the shallows and turn the sea red.
The distribution of marine life is based on the direction of the nutrient-rich currents and the intensity of the sun’s rays.
Smooth white-eyed sharks are particularly good at catching injured fish.
Hammerhead sharks gather in the largest schools in the ocean, sometimes with thousands of sharks cruising around a submarine mountain at the same time, because some of the creatures here can do cleaning for them.
Sardines → pond geese; sardines → white-eyed sharks; sardines → true dolphins.
Krill → Black-browed Albatross
Jason’s Spire is a remote island on the west side of the Falkland Islands, home to the world’s largest albatross habitat.
The daily light and heat brought by the sun is necessary for the growth of tiny plankton, the foundation of all marine life.
As the sun disappears over the horizon, a billion metric tons of marine life rises from the depths to search for food near the surface. Eating plankton under the cover of darkness, but not at all safe from other predators trailing in the ocean. At the break of dawn, the whole party returns to the safe embrace of the deep, dark waters.
The moon’s gravity causes the daily rise and fall of the tides. When the moon is neither full nor new, the tides are at their weakest and the sea is calmer.
The annual cycle of the Sun brings the most comprehensive effect on everything. The position of the sun relative to the earth changes throughout the year, which is also responsible for the seasons.
A single female herring can lay 20,000 eggs.
The migration of the gray whale is one of the longest in marine life, a total of 12,000 miles round trip. It is led by males and females that will not give birth. At the end of the line are the females that have just given birth. The strongest juvenile whales can only swim a few nautical miles per day (the endurance swim lasts about three hours).
The killer whales follow the gray whales on their annual migration. The killers are usually super mischievous, calling out to friends and screaming, but once they spot their prey, they quiet down like a collective switch. The killer whale’s prey is the young whale.
The killer whale’s body is only half the size of a female gray whale, whose tail fin can cause a lot of damage.
After six hours of hunting and feeding, the killer whale gets the young whale as a trophy, but only eats the jaws and tongue of the young whale.
On the dark bottom of the sea, a blind eel can eat carrion that is more than several times its own weight in a few hours.
02 Deep Sea
More than 60% of our planet is covered by more than a mile of ocean.
The deep ocean floor is a world of unprecedented wonders, with new species discovered on almost every dive.
More people have been to space than have been to these deep waters.
A sperm whale floats up for a breath that will keep it underwater for an hour.
Survival in the Microminerals depends on the difference between seeing and not being seen.
After sinking to 1,000 meters of deep water, we enter a dark zone where no sunlight can penetrate, the temperature of the water drops below four degrees Celsius, and the pressure is a hundred times higher than on land.
Sunlight only has a direct effect on the seawater a hundred meters above, photosynthesis can only take place here, and coral reefs can only be formed here.
Crossing the edge of the reef, you immediately enter another world where survival is not easy, only animals, no plants.
Only five submarines in the world have been able to dive the Great Ocean Basin, and they have explored only 1% of the basin.
In the middle of the Ocean Basin, there exists the largest geological formation on Earth – the Mid-Ocean Ridge – and also the largest mountain range on Earth, stretching over 80,000 miles.
At the surface, water turns to water vapor at 100 degrees. But at the bottom of the sea, under tremendous pressure, water remains in a liquid state even at 400 degrees.
Pompey worms can endure temperatures of more than 80 degrees, and are the most heat-resistant animals known to date.
03 Vast Ocean
Thousands of miles away from the land, the ocean is the most lifeless place on earth, as if it were a marine desert. But here also live some of the most agile and fierce sea hunters.
Red-fleshed sailfish are fierce carnivores. It hunts during the day and eats sardines.
The chances of survival of a juvenile yellowfin tuna may be only one in a million .
The fork-tailed petrel dances on the surface, not in a lovely waltz, but actually hunting for food. As they mockingly soar, they pick up scraps of food, such as eggs, from near the water’s surface.
Mackerel, the only way to resist predators is to gather into a ball. Any small fish that breaks ranks will be eaten immediately. There is still a slight chance of survival in a grouped pellet.
Sailfish are one of the fastest swimming fish in the ocean. Sailfish rely on their eyesight so they usually move during the day. When the sailfish is hyperactive, the body changes color and appears as a blue stripe.
Flying fish, are on the menu of all large carnivores, so they spend their lives fleeing for their lives in the sea.
Any piece of floating material in the sea is cover for the small fish.
Turner fish are the ultimate bony fish of the sea. Turnerfish live mostly in the deep sea, feeding on jellyfish. Occasionally they go near the surface to warm up.
Flying spinner proto-dolphins will leap out of the water in a flying leap, which is apparently just a social gesture. Because the prey is quite abundant, there are hundreds of them gather here to show their skills.
