Manatee

Sea cows, sounds strange, isn't it? Manatee or dugong, the so-called dugong or fish tale, is a medium-sized marine animal. Although the Vietnamese fishermen say they are "fish", in fact, this is a kind of mammals that live in the sea. This is an interesting legend, seaman who sees manatees in western countries, they think they are fish They should be born of the legend, "Mermaid" or "Mermaid" once upon a time.

1. Manatees and understanding

The manatee is what look like?

Manatees are mammals living in the ocean, gray skin, very close to the elephant connection. Unlike in the terrestrial animal such as cattle or cattle sea hare, not too much hair. The mother's delicate skin, only a few feathers scattered on the skin. Their head is round, two small eyes and a big mouth. Their limbs like oars, no nails.

Adult sea cows, ca. 2,7m - 4m from 250 to 300kg pounds. You are the manatee's growth of about 3 feet, weighing 20 35kg.

With the direction of manatee swimming on the tail. It changes direction with two forelimb swimming. Swim slowly, about six mph speed equivalent to bicycle travel the sea cow was slow, but can be transmitted over a long distance in 600 kilometers - can be a The bees for several days. A lot of evidence, the manatee living in regional boundaries in our country, in the Kien Giang Province (South), Guangning (North), show that the manatee has the ability to immigrants crossing the border [2].

Manatees communicate with each other's voice, voice low, or high range sound like a dog.

Do manatees eat what?

Manatee animal eats plants. Most love food is in the manatees. Every day they eat a lot of seaweed large (about 28-40 kilograms of seaweed) have enough energy. The manatee bones below the water heavy help find eating eat grass and sea, the manatee has upper and lower direction of food. They extracted two teeth and chewing grass of the sea.

The growth of manatees?

From the 13-15 months of pregnancy. You were born the first manatee children swim in the water on the surface to breathe air feeding, will follow you forever, until it was 1 or 2 years old. After birth, I also hurriedly manatees eat grass N we. Adults, from the age of 6-17, every 3 - 7 years.

Life is a kind of high age are manatees. In the favorable environmental conditions of the equipment, they can live up to 70 years or more.

Do manatees live in where?

Manatee life is lonely, although sometimes they also focus on personal life.

Love life in the Gulf and the manatee ranch, thermocline ditches, mangrove-covered areas, landing in the island covers. This is the grass, the sea is usually large.

2. Manatee how?

The sea had a significant reduction in the number of cattle, even in these places too much. The manatees have disappeared in the island of Taiwan in such a place, maples... Manatees in the international red book, in the high-risk group of extinction. In the "Vietnam manatee red book" list is a critically endangered species, developed to prohibit all forms of.

Previously, the manatee popular in Vietnam Ha Long Bay beach area, Qinghe, Kunlun, wells. Current estimates are only about 10 people living in Kunlun about 100-300 and lives in Dao Phu Quoc, the largest I hope [4].

3. Why?

One of the reasons leading to a severe reduction of state measurement in Vietnam around the world is like the manatee for hunter/overfishing. In addition, the marine pollution source - the cause of seagrass depletion C is the manatees eat is one of the reasons Bi n pushed cattle to the brink of extinction [five].

A hippocampus

The hippocampus is a very unique biological world ocean. Their head and neck shape like a horse, so they are called "hippocampus" or "naval code". They have the ability to change the color of the body and the surrounding environment, therefore, these fish horses have very diverse colors. Let's find out these mysterious interesting creatures!

1. The secret of the hippocampus

The hippocampus is special!

Do you know no Linyu as we imagine, there are the bones of the body in the outside? They have no teeth and stomach. Because of this, the food into the digestive system, and then quickly leave. This would explain why to eat hippocampus and hippocampus using continuous pumping mouth and small animal plankton near her. Some horses are "all fish", they can eat shrimp sea for 3000 hours a day [1].

It has very good eyesight. Their eyes can work independently, such as an eye to see in front of and behind the eyes. This is very useful, looking at the dangerous food and observation.

In swimming is good. They move through the beating of a small fin at a speed of 35 consecutive / sec. In the small part of the pectoral fin, the back of the head, such as rudder for the hippocampus.

In the tail is very special, it has the ability to keep the wound in the small plants are not water for the hippocampus.

Hippocampal growth?

Unlike other fish, fish, the horse is an animal is "loyal". They have only one partner, hippocampus and hippocampal association did not hatch to take care of you.

The hippocampus in abdominal mass like kangaroos)! When mating, the female spawning pocket male, and male sperm and eggs in your body. Male eggs until hatching, the new package, launched the development of the complete immature environment. This process lasts about 45 days.

In when you were born, they just use a cotton candy child. They immediately find other horse tail fish swim together, and a small group. The kangaroo, horses, once released, will not come back to my bag in. Hippocampus is only 1 / 1000, your survival and growth.

In the survival of from about 1 to 5 years, was dependent on the hippocampus.

Do seahorses live in where?

The hippocampus can be found in most tropical and temperate sea world. However, most seahorses live in the southeast region of the sea and the Panama Canal, South Africa, especially in the sea, grassland, rupture The HO and mangroves. The world has found 54 kinds of the hippocampus [2].

In Vietnam, there are four, respectively located in the hippocampus coast from north to south.

Hippocampus: in the Beibu Gulf, South Ministry (from Da Nang to ride).

2. A decrease in the hippocampus a day!

At present, in the list of endangered animal red rank in the international convention to ban trade and world trade in trade in wildlife is critically endangered (Reference) [3] in Vietnam with. M, we also observed in the hippocampus were greatly decreased.

3. Why?

In the hunting and trade market, the traditional treatment in many places from Vietnam and China hippocampus treatment of bone and joint diseases and physiological. The hippocampus also hunted, keep in the aquarium landscape. Here, we can only have died soon after about 6 weeks [4].

In addition, compared to other marine organisms, the hippocampus is very fragile, because of these substances or interrupted the main food source. The swimming ability limit, the hippocampus cannot be K. Regional pollution problems quickly [5].

Bioenergy is the first extinction of whale in the next 300 years

Bioenergy is the first extinction of whale in the next 300 years

In the Gulf of Mexico mysterious whale falls in the critical state, and the high capacity of the future will become extinct.

The game king (P4): sea power in misunderstanding clarification on Orcas

Tragedy: the sea whales eat every day hundreds of thousands of pieces of plastic waste

Experts have warned of a danger of extinction in the Gulf of Mexico whale. They are the brides whale (read bruh DIHS), is also the first whale 300 years really in trouble, because of whale the Atlantic gray, and finally disappeared.

The bridge whale can move around the world. They are also in the whale is the only existing thermocline near the equator, it is also called "tropical whale".

However, there is a community in the Gulf of Mexico is considered to be a separate branch, currently on the IUCN list are critically endangered is that "extinction" is one step.

At present, scientists believe that 50 people live in the Gulf of Mexico. This is a relatively "dream", because the results of the survey in 2009, but the result is low only 33.

Brandt whales live in the depth of 100-400, but not too much information, because the number is very rare. Only they know, like narwal photos, they depend on small fish in the sea.

The problem is he in the Gulf of Mexico, under the bottom of the net fishing methods, are very common. In 2003, the whale in North Carolina after the death in the fishing tool.

The development of tourism and petroleum exploration is a big threat to whale, whale, 85%. Death, just because of the collision when moving.

In addition, some experts believe that the sound caused by the vibration of ship oil, also let the whales come under pressure, the harm to our health.

Finally, the reason is the most dangerous: oil spill. In 2010, almost half of the pants will be affected, because of the Deepwater Horizon oil spill. An estimated 18% to 22% serious health effects and whale, this almost barren.

According to the plan, this year will continue to be the 2022 human detector into this area, what if there is no change, they will almost certainly happen extinct.

"The first step is to increase the perception of the community about a whale. After that, we can protect them." the report quoted published in the Journal Nature.

The shark appeared in the volcano, but no one can explain why he or she go there

Sharks usually live in the sea environment or soda, but found the sharks in the water on the volcano is what makes science shocked.

There is no way out, Yang Shan decided to let puma the miserable life of the soul!

The first shot two sharks crocodile of the same scene to eat the bodies of 20 tons of whale

The original dog found at the top of the mountain the most hidden world!

In the study of the volcano-hydrothermal and geology groundwater kavachi Solomon islands scientists, National Geographic Channel (Nat Geo) was very surprised when he found the sharks live here.

Suddenly found in the volcano Lake Karachi

Not only that, there are at least two kinds of sharks live here, in addition to sixgill ray fish, Rose Bay (fish and bream) also found that although the shooting conditions living in the lake is very hot water and water Do the acid.

At a depth of 24 meters, the development of the Nat scientists Geo Brennan Phillips film has been very rare and powerful ecosystem, especially in harsh environments.

Dr. Brennan at the University of Rhode Island Philip said: "when a diver near the deep lake bottom temperature to come back, because there is very hot, as their skin began to burn water acid".

The water environment is very bad, scientists need to put special waterproof camera instead of direct measurement of diving.

Surprised, put your camera, look at the video, the scientists found the photo, a hammer (fan shark young hammerhead shark (Carcharhinus sickle silk) could be found in the sea).

Phillips said: "the creatures living in a place where we all know is acid and thermal pollution more than any place".

Do sharks formed in the Lake volcano. Perhaps the exploration of the most incredible and impressive, the reason we are here is a problem, let the scientists a headache.

Marine biological research work from Gothenburg University in Sweden, also found that the water pollution is caused by the change of acid acts like a shark swimming time than not sleeping or make your taste And prey.

Kavachi is one of the underground volcano, the most active volcano in the Pacific, another name is rejo TE kvachi (barbecue), a recently active volcano, which is in 1939.

After the 11 eruptions, finally, it is worth noting that in 1970 and 1976 two in 1991 - the power of this activity has created a new island, then drown.

The big belly Shanyin fire to water heat, chemical and many another original group dry Lake volcano eruption temperature and acidity has been very high, it seems all the bottom of the ecosystem Oh, very poor.

A study on the Earth Observatory of Columbia University Ramon - Doherty, American underground volcano activity in Karachi is also linked to changes in the earth's orbit.

Discover the treasures of the sea is the world's greatest.

 


Because the credibility and quality, it loads the treasure, a lot of searches and open debate is between countries have next to.

The ship sank, which is considered as the "Holy Grail" (Holy Grail) because of the very high value of cargo quality, but lost at sea, this is a saint Jose, a Spanish galleon in Eighteenth Century.

Because of its high reputation and real estate, many searches was opened and became gold searching the sea all a cruel game.

Three years ago, an international panel of experts led by the National Archaeological Discovery Columbia Naval Academy, the ship sank off the coast of Columbia, the value of it can make your relatives He was surprised.

The estimated value of the treasure ships sunk in the 12,6 million pounds (the US $1 billion 700 million, according to SSA)! Turn it into a boat carrying pieces of the most valuable treasures are found in human history.

According to the Institute of Oceanography in Woods hole (whole), the ship was found by an automatic underwater robot's name - Rimes 6000 is a robot to help find the ship sank the French air force in 2011 447.

The positioning system and connected to the water on the robot, the researchers found that the sinking of the ship San Jose position at a depth of 600 meters in the sea near the island of Munier in Rosario, Rob who said the chairman.

The Engineer LED expedition of Mike who Purcell: "the ship sank or covered by sediment part layer, but the camera photos, we can see the details of the ship, at sufficiently high resolution, so that you can see He stood in the Chinese cultural export machine gun."

According to the study, the ship has sunk on June 8, 1708, when 600 people and 62 guns as the treasure of gold, precious stones, such as emerald and the British ship during the first World War, the war of succession to the throne of London Kazakhstan.

Why is the name of "Captain America Steve Roger?" The only real fans!

The salvage of the ship and the historical treasures of the ownership dispute

This is a ship owned by King Philip V (Spain) fill in precious metal mining from Peru and Bolivia colony, and then put the treasure back to Spain is to help supplement the financial resources. U c succession war against the British.

San Jose Jose is the ship under the command of captain Fernandez Santillan, two different names to escort ships, "San Joaquin" and "Santa Cruz". This is the Gilded Age Spanish Empire at war and plunder of wealth from the U.S. - Latin.

300 years after the sinking of the ship, the Columbia government launched a search for the cooperation of the company is a private Columbia President Juan Manuel Santos said: "this is an exploration of the sea to the Great Heritage The history of mankind."

However, the ship and the value of the property is huge, it is still carrying the debate between the owners and the legitimate government, Columbia sea fleet of search Armada (SSA) of the United States.

At first, the government of Columbia has agreed to SSA about shared property found on this ship, but if all the treasures belong to Columbia, in court, when 2011 (from UNESCO).

It is expected that there will be an open museum of cultural relics on display, the salvage ship shaft.

This is the sharp teeth of snake sharks and 300, you can see in a nightmare

We really know what is the ocean? Near 95% has not been found, it seems that every day, we found a new thing...... This is worrying.

Recently, people found a prehistoric shark from the age of dinosaurs troubled teeth, drifting on the coast of Portugal.

Marine biology in this nightmare like a snake is a kind of adventure sharks, one of the oldest and most obsessed lead to the existence of our planet.

When you from the prehistoric kind, such as T Rex and Triceratops disappeared for a long time, also got great sharks swimming in the content area, the surface of the depths of the ocean is according to the scientists.

So they know that this is a fuzzy event sounds like a horror story. Where a group of scientists at the European Union in the "groping" deep layer in the Atlantic in November / 2017, attempting to make the "production to reduce unnecessary mining in the fishing trade".

However, they unexpectedly found creatures in the most precious and most ancient creatures of the earth may be a good image for the story of the serpent sea in Nineteenth Century.

The seaman who didn't know sharks began, they found that the shape does not change because of the supercontinent Pangea cup broke. If you want to know what it is, please answer: it is very terrible.

Sharks can grow up, to begin with, 1,83 meters tall adults. It is named after the corrugated edge smoothing their inherent and a lovely element. But in the end.

The shark in a short fuse head is 300 reasons, you'll never want to leave the beach for a swim: it has hundreds of needle-sharp teeth, put in the 25 row short.

He used to beat fast insertion to drown in the teeth of sharks, fish, squid, and octopus.

I know very little about the shark started because it lives in the deep sea coast of Japan, New Zealand, and Australia.

More than 800 thousand years on earth there, very rare sharks and humans began an activity or watching movies, in its natural habitat. A seaman who see sharks from the nineteenth Century - the original panic, this is the first record.

The shark has created has the advantages of simple structure, perhaps the lack of nutrition of water in its living environment. As for why it can live longer than their compatriots from the Cretaceous period, no one can accurately answer.

Therefore, at the present time, it is still a warning that has caused an extreme biological problem to exist, floating in a week we have seen is the "surface of the calm sea.

Every day, scientists have been aware of these animal swimming in the sea area has not been found, and then let them on the Internet for the world to see. For example, in 2017, a group of international scientists. Supported by the Australian Museum, I found some methods than 3,2km marine organisms.

They want to know what kind of creatures live in eternal darkness, great pressure, temperature, and not suitable for life

Scientists have found that those who like a red crab is composed of more than a dozen government thorns. They found a fish's coffin - a ruse, eyes are blue, redfin, with a rod hanging on a piece of meat smooth It makes the new approach and attacks my head.

So, maybe the beach is the safest place until we know more about swimming creatures than

"The mysterious" found coral forest area of more than 1000 years, deep sea 2.300m

The brutal raids, "the monster from the East" exposure of the forest in your mysterious 7000 years

In fact, the knowledge of the ocean, we humans are very rare. Even a joke said, "all of our space explorations to the moon or Mars than Earth's oceans."

Fortunately, in Oceanic and Atmospheric Administration (USA), humans gradually found the secret ocean marine Explorer Okeanos noaas. This is the only ship dedicated to funding more to explore the mystery of the sea.

Discover the mysteries of the coral forest more than 1000 years old, he 2.300m deep seabed.

Recently, Chinese Okeanos conducted exploration in the area of Mexico bay. And don't believe, he found a "forest Coral" diffuse, in the depth of 2.300m in Western Florida (United States).

8 million people lost their jobs, President of the University and college khxh NV: the robot cannot "imitate"?

Scientists estimate that these coral reefs have reached the age of one hundred, even more than one thousand years are likely to.

However, scientists amazed. Coral reefs are being developed along the mountain of the sea, forming a row, this is actually a layout have many advantages.

For example, the effects of nutrients and water they can absorb the flow. In addition, with other elements such as geology and food available to them in the development of a good breakthrough.

The power of destruction "bite prey ferocious sea"

The famous "prey ferocious sea", with the terrible power of killer whales bite, a moment can crush big game!

The screen flashes the Cobra Attack let fish rattlesnake "not timely yawn"

A very poisonous snake's name, you can travel in the opponent "conflict" in Fansipan

The famous and effective foraging strategy is considered to be very cruel, Orcas eat the most ferocious mammals in the world's oceans!

Animal body tall (the longest record of 9,8 meters, weighing 10 tons) are swimming before the soul, they reached the maximum speed reached 56 km / h (equivalent to 15 m / s).

A terrible animal, rather than the sea, whale in all life in the world of marine areas, from the cold and warm the earth.

Because of the speed and advanced in their prey, (scientific name Orcinus orca) are many different names, including dolphins: Sea Wolf (Seawolf), black (ground), dolphins (dolphin Grampus).

"They love to eat is very rich, seals from all the small fish, whales, on the back of the great grey. No love in our white.

Orca is a famous hunting prey to escape. They are active, active, clever to...... Ruthless

A terrible force to create the victory gave them to destroy the killer whale hunting is bite force of two species of marine animal a zero.

The sheep feeding habit (three to five in a hunting), "sea wolf" to perform the operation, the dorsal gray whales gray back you leave me.

Then, with my body strength and speed have a ton of origins in the death of the victim.

Otherwise, they may use these functions have 50 teeth are very sharp, let tearing bite and terrible power, to 1 tons / cm2 whale shark chaos can take courage once more, before biting and many other unfortunate victims A good way to enjoy.

So, if there is a strong bite according to the list, one of the most terrible animal world, Orca is ranked third after the two giant crocodiles on the earth.

The blue whale is the largest animal on earth

The blue whale is the biggest animal that ever lived on earth great marine mammals is considered to be the ruler of the sea the length of up to 100 feet (30 meters), weighing 200 tons on the tongue. We can use a heavy heart and an elephant, with a car near them.

Eat krill mode

The blue whale lived in a special diet consists mainly of small crustaceans called krill or animal. Sometimes in these years, a mature blue whale can consume about 4 tonnes of krill per day.

The blue whale is a function of the narwhal, which means they have a nail like an angle function embedded in theirs. After this huge animal mouth to eat and swallow a mouth to expand the waters, then use the tongue to a huge water, put the food from the mouth with the angle.

Color and shape

The blue whale is blue in the water, but when they are in the water floating green and gray. In particular, a bright yellow at the bottom of our stomach, because millions of microbes live on the surface of the skin. I have a body and then big flat head with a long tail like two slots for they can easily surf in the water.

Understanding these facts: the best killer

Behavior and communication

Blue whales live in the sea, all of the worlds, sometimes they also in swimming, but is usually a small group, or on their own. In the summer, we usually find food, in cold waters, and long-term migration VIs on the equator, arrived in the winter.

The swimmer often walks in the charming ocean five miles per hour but can speed up to 20 miles per hour, when they are excited. The blue whale is the biggest animal to send a voice of the planet. They can produce a series of moss sound, even in very good condition, we can hear the sound of all the way, even in 1000 miles. Scientists say that they do not use these sounds Only the communication with a keen sense of hearing to measure the depth of the ocean.

You are the blue whale

After the blue whale ready to enter a new life in the world ranking will be the biggest animal on the planet. After about a year, living in the mother's womb, a birth weight of the blue whale can grow to 3 tons, up to 25 feet (about 8 meters). They do not eat what to drink milk, increase 200 kilograms, the first year of every day.

Life

The blue whale is the earth's oldest animal. Scientists have discovered how the number of layer of wax died in helix whale, their life expectancy. The blue whale was found the oldest and the estimated life around the age of 110. In addition, estimation of life expectancy for the blue whale generally falls from about 80 to 90 years.

protect

This fierce hunting whale oil is hunted to the brink of extinction in 1900. About from between 1900 and 1960, about 360 of the blue whale were killed, because of the different economic goals. Finally, their protection is the International Whaling Commission in 1966, but the number of recovered only a whale is very small, very small.

The blue whale has many enemies, but they are the victims of being attacked by sharks and orcas. In addition, there are also many cases of whale injuries or death each year due to the impact of a fishing boat big.

Don't neglect: Moby Dick and 10 + basic information need to know

Some interesting information on the blue whale you may not know:

When the whale is not breathing, water from the hole ejection spark in his breath
