What is the heaviest creature in the ocean

What is the heaviest creature in the ocean, the ocean accounts for one seventh of the earth's area, in the ocean is also the existence of many creatures, the ocean's biological species is very much, a lot of people want to know about the heaviest creatures in the ocean, the following introduction to the ocean is what is the heaviest creature

What is the heaviest creature in the ocean1

The heaviest creature in the world is the blue whale.

The blue whale is not only the heaviest cetacean, it is also the largest animal in existence, by far the largest mammal. It typically measures 2,200-3,300 centimeters in length and weighs 150,000-180,000 kilograms, which means it weighs as much as more than 25 African elephants, or 2,000-3,000 people combined. Fortunately, thanks to ocean buoyancy, it doesn't need to struggle to support its weight as much as a land animal, and in addition the large body helps maintain a constant body temperature.

The blue whale has a light blue or mouse-gray body all over, with a light-colored, finely mottled dorsal surface, a white chest with white spots and 20 or more pleated grooves, and a belly covered with pleats up to the umbilicus with ochre-colored yellow spots. The female has breast furrows on either side of the genital pores, containing slender . Nipples.

The head is relatively small and flattened, with 2 blowholes, situated on the top of the head, the muzzle is wide, the mouth is large, the mouth is toothless, the maxilla is wide, projecting upwards in a curved shape, bearing black whisker plates, as many as 300-400 on each side, and is 90-110 cm long and 50-60 cm wide. A lot of wax accumulates in the eardrum every year, and its age can be judged according to the thickness of the wax. There is also a white callus on its maxilla, which used to be a place where hair grew, but later, when the hairs were degraded, it left a wart-like flab that became a breeding ground for parasites.

Since this callus is not the same on each individual, and is like a differently shaped "hat", it is possible to distinguish between the different individuals. The dorsal fin is particularly short, its length is less than 1, 5% of the body length, the fin limbs are not too long, about 4 meters, with 4 toes, its back edge does not have a wave-like notch, the tail is broad and flat. The entire body is streamlined, looks like a razor, so it is also known as the "razor whale".

The margin is straight. Stinging grooves 55-88, the longest reaching the umbilicus. Baleen plates 270-395 per side. Body dark pale grayish blue dorsally, slightly lighter ventrally, mouth and baleen black.

Unlike other species of whales, which appear short and stout, blue whales have a long vertebral body that appears to be elongated. The head is flat and U-shaped, with a distinctive ridged projection from the upper lip to the dorsal stomata, and a dense concentration of baleen plates at the front of the mouth, with about 300 baleen plates (roughly 1 meter long) overhanging the upper jaw and penetrating about half a meter into the mouth. 60-90 grooves (known as ventral folds) run parallel to the body along the throat. These folds are used to expel seawater after massive swallowing.

The blue whale's dorsal fin is small and only visible briefly during dives. The shape of the dorsal fin varies from individual to individual; some have only a just-visible bulge, while others have a very striking, sickle-shaped fin. The dorsal fin is located roughly three-quarters of the way down the length of the body. When it is time to surface to breathe, blue whales raise their shoulders and stomatal area out of the water to a much greater extent than other large cetaceans such as fin whales and pompano whales. This often serves as a useful clue for identifying marine species.

When breathing, if the winds are calm, blue whales emit a spectacular vertical column of water (up to 12 meters, typically 9 meters) that can be seen from thousands of meters away. Blue whales have a lung capacity of 5,000 liters.

Is the largest creature in the ocean?

The largest squid in the ocean: the giant king squid

The giant king squid is about 20 meters long, but there may be even bigger ones in the deep sea, and it is speculated that the largest giant king squid is 60 meters. So if the king squid is really 60 meters, then the king squid is the largest marine animal.

The king squid lives in the Pacific Ocean, the Atlantic Ocean deep sea waters, body length of about 20 meters, weighing about 2-3 tons, is the world's largest lightless vertebrates. Its temperament is extremely fierce, to fish and invertebrates for food, and can fight with giant whales. Overseas there are often king squid and sperm whale fighting reports. According to records, once people witnessed a king squid with its thick horns and suction cups dead entangled in the sperm whale, the sperm whale put all its strength to bite the king squid's tail.

The two giants of the sea rolled around violently, churning up turbulent waves, and then both sank to the bottom of the water without knowing where they ended up. Most of these fights are won by the sperm whale, but there have also been cases where the king squid has clamped its hand over the whale's nostrils and suffocated it to death.

So the sea monsters that people encountered in 1861 and 1878, as quoted earlier, are definitely king squid. How big could the largest king squid be? This question is not easy to answer. People have measured the length of a king squid 17, 07 meters, the diameter of the sucker on its horns is 9, 5 centimeters. But from the captured sperm whales, there have been sucker scars with a diameter of more than 40 centimeters.

From this, it is assumed that the king squid that fought with this whale could have been 60 meters long or more. If there was a king squid of this size, it would not be far from the legendary Norwegian Sea Monster.

Now the largest known marine animal is the blue whale, the information is above.

As for the largest sea creature, it is the giant algae

The giant algae belong to the brown algae, and they are the longest in the algae kingdom. Most macroalgae can grow up to several dozen meters, and the longest can even reach 200 to 300 meters and weigh up to 200 kilograms. The algae are anchored to the reef by an entrainer more than 1 meter long. The center of the giant algae is a trunk, on which grows more than 100 twig-like stalks with small blades, some of which are more than 1 meter long and reach a width of 6 cm to 17 cm wide.

The blades have air sacs that generate enough buoyancy to lift the blades and even the entire alga. These air sacs are arranged in a regular pattern on either side of the main veins on the blade. Where macroalgae grow in abundance, the huge blades cascade over hundreds of square kilometers of ocean surface. Macroalgae is one of the fastest growing plants in the world. Under the right conditions, each macroalgae can grow 30 to 60 centimeters in a single day.

In a year, a single macroalgae can grow to more than 50 meters. Growing in the tropics, macroalgae grow all year round and can be harvested three to four times a year by seaside fishermen who collect them for a living. The lifespan of a macroalgae is usually between four and eight years. The longest-lived macroalgae can grow for up to 12 years.

If 1,000 macroalgae are planted per hectare of surface, 750 to 1,200 tons of fresh macroalgae can be harvested each year. Chironomus is native to the Atlantic coast of North America, Australia, New Zealand, Peru, Chile and South Africa are distributed along the coast. Our scientists introduced macroalgae from Mexico to China in 1978. At present, macroalgae farming has been successful in China's coastal areas. From now on, China's marine aquaculture in the algae has added a new force.
