Its maximum body length can reach 2.5 meters, weighing about 1,000 kilograms, is called the king of sea turtles.? The clownfish is a tropical saltwater fish.? There are 28 known species, and the clownfish has an inextricable **** biological relationship with the sea anemone, so it is also known as the anemone fish. Anemones with poisonous spines protect the clownfish, while the clownfish eat the anemone's digested remains, forming a ****born relationship.? Butterfly fish are small in size, rarely exceeding 20 centimeters in length. It swims like a butterfly and is brightly colored, hence its name. Colorful Fairy Fish? Colorful Fairy Fish is also known as Discus and Colorful Swallow. The color of the body changes with the light, when the light is dark, the body color is dark; when the light is bright, the color is colorful and rich, with stripes all over the body. Light and airy jellyfish in the azure ocean, inhabited by many beautiful and transparent jellyfish, one of them like a parachute like floating in the sea, graceful appearance makes people marvel. In the ocean, when you see these jellyfish, don't touch them, or you will be stung by their poisonous stinging cells, or even killed. Blue WhaleThe blue whale is the world's largest animal known to man, with a blue-gray color. The largest blue whale caught 33.5 meters long, weighing 195 tons, equivalent to the weight of 35 elephants. Beast of the "king" - the blue whale has a split starfish starfish body size varies, as small as 2.5 cm, as large as 90 cm, the body color is not the same, almost every difference, the most colors have orange, red, purple, yellow and cyan, and so on. Starfish also have a special ability - regeneration. Any part of the starfish can regenerate a new sea
2. Who can tell me the interesting information of marine life
1, will climb the tree fish Fish live in the water the main respiratory organs are gills.
Fish leave the water, gill filaments dry, bonded to each other, stop breathing, and life stops. However, there is a kind of mudskipper that can adapt to amphibious life living in the coast of China.
The mudskipper has a body length of about 10 centimeters, slightly flattened sideways, and two eyes above the head, like frog eyes, with a wide field of vision. It has large gill cavities and sealed gill covers that store large amounts of air.
The cavity of the epidermis is covered with a network of blood vessels, play a respiratory role. Its skin is also covered with blood vessels, the blood through the very thin skin, can be directly with the air for gas exchange.
The caudal fin, in addition to its role as a fin in the water, is also an auxiliary respiratory organ. These unique physiological phenomena enable them to leave the water, a longer period of time in the air In addition, the two right and left ventral fins of the elasmobranchs merge into a suction cup, which can be adsorbed on other objects.
The well-developed pectoral fins are arm-like, much like the appendages of higher animals. When it encounters hostiles, it moves faster than a human can walk.
The mudskipper, which lives in the tropics, often jumps on the beach at low tide to catch food, and prefers to climb to the roots of mangroves to catch insects. Therefore, people call it "the fish that can climb trees".
2, the magical "devil fish" "devil fish" is a huge tropical fish, the scientific name of the front mouth manta rays. Its size and strength often make divers afraid, because as long as it launched the anger, just use its powerful "wings" a beat, will touch the broken bones, to the death of people.
That's why people call it the "devil fish". Sometimes manta rays use its cephalic fins to hang themselves on the anchor chain of the boat, dragging the boat quickly running around the sea, so that fishermen mistakenly think that this is the "devil" in the monster, but in fact it is the manta ray's mischief.
"Devil fish" like to swim in groups, sometimes submerged seabed, sometimes male and female pairs rose to the surface. In the breeding season, manta rays sometimes use both fins to beat the water surface, jumping up in the air, can jump out of the water, in the water more than one person high above the "glide", when the water, the sound is like a cannon, the waves for miles, very spectacular.
Manta rays look intimidating, in fact, it is very gentle, only to crustaceans or groups of small fish and shrimp for food. The two fleshy feet on its head are its cephalic fins, which protrude forward in a flipped position and are free to rotate, and it is these cephalic fins that manta rays use to drive away food and pluck it into their mouths to devour it.
3, the fish will make a sound General people think that all fish are mute, obviously this is not true. Many fish make a variety of surprising sounds.
For example: Kangji eel will make a "bark" sound; electric catfish screams like a cat's wrath; box triggerfish can make a dog barking; pomfrets scream sometimes like a pig, sometimes like ***, sometimes like snoring; seahorses will make a monotonous sound like a drum. Stonefish are known for their good calls, which sound like rolling, drumming, the flight of a hummingbird, catcalls and whistles, and their calls are especially common during reproduction for the purpose of clustering.
4, the king of the sea - sharks in the vast ocean, known as the "king of the sea" sharks all over the world's oceans, there are more than 70 species in the China Sea (about 350 species worldwide). Most of the sharks are favorable and harmless to human beings, and only 30 kinds of sharks will attack human beings and ships for no reason.
Sharks do have a bad reputation for eating people, but not all sharks eat people. The nostrils of sharks are located in front of the mouth on the ventral surface of the head, and some have an oro-nasal groove that connects between the snout and mouth corners, and the folds of the olfactory sac increase the area of contact with the outside environment.
It has been determined that the total area of the olfactory membrane of a 1-meter-long shark can reach 4842 square centimeters, so the shark's sense of smell is very sensitive in a few kilometers away from it can smell the smell of blood, the animals in the sea, once injured, are often attacked by sharks and killed. Sharks generally only eat live food, and sometimes eat carrion, food to fish-based.
Some people in the skunk shark stomach found dolphins, waterfowl, turtles, crabs and a variety of fish, etc.; in the phocaenid shark stomach had taken out a very large sea lion; hammerhead sharks food is fish and crabs; nurse sharks, star sharks, the bait to the small fish, shellfish, crustaceans are mainly. Sharks in search of food, usually one or a few in the water cruising, once found the target will quickly strike to devour it.
Especially in the ship or airplane crashes have a lot of bait in the water, they gathered to, in a state of excitement and frenzy of sharks almost eat everything encountered, and even kill each other for food. Sharks belong to the cartilaginous fish, there is no swim bladder, regulating the sinking and floating mainly rely on its very large liver.
For example, in the southern hemisphere found a 3.5-meter-long great white shark, its liver weight of 30 kilograms. Scientists have shown that the shark's liver relies on the increase or decrease of diacylglycerol ethers, which are much lighter than normal triglycerides, to regulate buoyancy.
Although sharks are ferocious and repulsive, their whole body is a treasure, and they are economically important fish. Shark liver is particularly large, rich in vitamins A, D, is an important raw material for the production of cod liver oil; shark skin can be leather, its fins that is the sea food treasures - shark fins.
Sharks can also be used for medicinal purposes. According to scientists, sharks rarely suffer from cancer, even if the most terrible cancer cells transplanted into the body of the shark, the shark is still safe and sound.
Because its cells will secrete a substance, this substance can not only inhibit cancerous substances, but also can make the cancerous substances reversed. 5, the lovebirds in the sea - butterfly fish When people see the butterflies fluttering on land will be praised, and the butterfly fish's reputation, is because this fish is like a beautiful butterfly.
If people want to choose the beauty of coral reef fish, then the most colorful and fascinating when the butterfly fish is the first. Butterfly fish valley called tropical fish, is offshore warm-water small coral reef fish, the largest can be more than 30 centimeters, such as fine-grained butterfly fish.
Butterflyfish body side flat suitable for in the coral thickets back and forth, they can quickly and agile fade in the coral branches or rock crevices. The butterflyfish's long muzzle and small mouth make it ideal for reaching into coral caves to catch invertebrates.
Butterflyfish live in the colorful coral reef plate, with a series of adaptive environmental skills and its brilliant body color can change with the surrounding environment. Butterflyfish body surface has a large number of pigment cells under the control of the nervous system, can be expanded or contracted, so that the body surface shows different colors.
Usually it takes a few minutes for a butterflyfish to change its body color, while some only take a few seconds. Many butterflyfish have very clever camouflage, often hiding their true eye in a black stripe across the head, while leaving a very conspicuous "false eye" on the caudal peduncle or behind the dorsal fin.
3. Ten tips about the ocean
1. People often like to use the color blue to describe the ocean. In fact, the color of the sea water, from deep blue to turquoise, from slightly yellow to brownish red, and even white, black, not just blue.
Seawater and ordinary water are colorless and transparent, the ocean color is determined by the optical properties of seawater and suspended substances contained in seawater, the depth of seawater, the characteristics of clouds and other factors. As we all know, sunlight consists of seven colors: red, orange, yellow, green, cyan, blue and violet. These seven colors of light have different wavelengths, and the wavelengths become shorter and shorter from red to violet. Long-wave light has the strongest penetrating ability, and it is most easily absorbed by water molecules, while short-wave light has a weaker penetrating ability, which is prone to reflection and scattering. Seawater has different degrees of absorption, reflection and scattering of different wavelengths of light. Longer wavelengths of red light, orange light, yellow light, shot into the sea water, with the increase in the depth of the ocean is gradually absorbed. Generally speaking, in the depth of more than 100 meters of the ocean, these three wavelengths of light most of the seawater can be absorbed, and can also improve the temperature of seawater. The shorter wavelengths of blue light and violet light will be strongly scattered and reflected when they meet the purer seawater molecules, and the ocean will appear azure or dark blue. Nearshore seawater due to the increase in suspended solids, particles larger, weaker absorption of green light, scattering is stronger, so more light blue or green.
The shortest wavelength of purple light, the strongest reflection, why is the sea water is not purple? Scientific experiments have proved that the original human eye is a certain bias, the human eye on the ability to feel the violet light is very weak, so the seawater reflection of the purple is very insensitive, and therefore blind, on the contrary, the human eye on the blue, green light is more sensitive.
In addition, because the sun is sometimes hidden in the clouds, and sometimes through the clouds to release the light, the color of the ocean will also change. The color of the ocean also depends on how high the sun is above the horizon.

4. under the sea interesting animals what happens to the interesting things essay 大全200字
This morning, my mom took me to the underwater world in Gulangyu Island, Xiamen, where I saw a lot of fish from the bottom of the sea, and now I'll talk about it.
My mom and I took a boat to the island of Gulangyu, and my mom said, "Let's go to the underwater world together!" I happily agreed. To the door of the underwater world, I saw a stone carving large octopus, my mom and I drilled through the octopus from under the claws, to the front of the octopus. I saw the octopus looking at the gate with its teeth and claws open, seemingly welcoming visitors from all over the world. My mother and I continued to walk inside, I saw many sea creatures, there are colorful coral, there are endangered species of large sea turtles, there are rare large sea dragons, seahorses, penguins in Antarctica and so on. Among them, my favorite is the cute penguins, they waddle around on the artificial snow, these cute little guys are really enjoyable. I also visited the Sea Turtle Pool, the turtles were as big as a big table, they poked their heads out of the water, and their claws were swinging around, as if saying, "Hello! Welcome to the underwater world!" I also saw a lot of sea creatures, know a lot of knowledge, today I really happy.
The underwater world has opened my eyes and let me see many underwater creatures.
5. Ten tips about the ocean are urgently needed

6. What is the knowledge of the ocean
The ocean (SEA) is the broadest body of water on Earth, the center of the ocean is called the ocean, the edge of the part of the ocean is called the sea, communicate with each other to form a unified body of water.
The Earth's surface is separated by the continental land for each other connected to the vast body of water known as the ocean, with a total area of about 360 million square kilometers, accounting for about 71% of the Earth's surface area, the average depth of about 3,795 meters. The ocean contains more than 1.35 billion cubic kilometers of water, accounting for about 97% of the total amount of water on Earth, and can be used for human consumption only 2%.
The Earth's four major oceans are the Pacific, Atlantic, Indian, and Arctic Oceans, most of which are bounded by land and seafloor topographic lines. So far, only 5% of the seabed has been explored by humans, and 95% of the ocean floor is unknown.
Extended information:
1, the distribution of ocean currents 1, in the equator to the north and south latitudes between 40 ° or 60 °, the formation of a low-latitude circulation, the direction of its flow in the northern hemisphere clockwise, the southern hemisphere into the counterclockwise direction. The western part of each circulation is warm and the eastern part is cold.2. A high-latitude circulation is formed north of 40° or 60° north latitude. The direction of its circulation is counterclockwise, and the western part of the circulation is cold and the eastern part is warm.
3. The North Indian Ocean north of the equator is located south of the Tropic of Cancer, which is a monsoon current. In winter, the northeast monsoon, the surface seawater to the west, the current was anti-clockwise flow; in summer, the southwest monsoon, the surface seawater to the east, the current was clockwise flow.
4, east-west flow of ocean currents, in addition to the southern hemisphere's westerly drift, have a warm nature. Ocean currents have a great impact on the continental climate along the coast, cold flow through the region of the climate has a cooling, humidity effects; and warm currents on the climate along the way to warming, humidification effect.
Second, the reason for the formation of the water in the sea is always in accordance with a regular clear form of flow, the cycle is uninterrupted, known as ocean currents. One of the more famous is the Gulf Stream, the narrowest point is also as wide as 50 miles, the flow speed of up to 4 kilometers per hour, along the coast of North America north, across the North Atlantic Ocean, regulating the climate of Northern Europe.
The North Pacific Current is a similar warm current that flows northward from the tropics, raising temperatures along the west coast of North America. The prevailing winds are the main force that keeps the current in motion.
Differences in the density of sea water are also a cause of the current. Cold water is denser than warm water, so cold water sinks and warm water rises.
Based on the same principle, cold water near the poles also sinks and flows below the surface towards the equator. When it reaches the equator, this current rises, replacing the warm water that flows with the surface currents towards the poles.
The coasts of islands and continents also have an effect on the currents, either by diverting them or by dividing them into tributaries. Generally, though, the major currents circulate around the various ocean basins.
As a result of the Earth's rotation, ocean currents flow in a clockwise direction in the Northern Hemisphere and in the opposite direction in the Southern Hemisphere. Baidu Encyclopedia - Oceans.
7. What are the interesting animals, plants and characteristics of the seabed, please list 4 kinds of each Thank you
Animals: the activities of the seabed animals and the protection of sea cucumbers There are many kinds of sea cucumbers, the color of black, brown, white, etc., like to inhabit in the waves of the quiet and stable, seaweed congested fine sandy seabed and rocky reef bottom.
The sea cucumber lives deep in the seabed and does not swim, but just crawls on the seabed with its tube feet and muscle stretching. The crawling speed is quite slow, only four meters per hour.
The special and marvelous protection art: when the storm is coming, it hides in the crevice of the rock. When the insidious and cunning sea plate car, greedy and vicious sharks salivating to sneak up on them, the alert sea cucumber quickly put the body cavity of the viscous and long intestines, twigs like the lungs of the water out of a brain, so that the strong enemy to eat a meal, and their own backlash with the help of the viscera, escaped without a trace.
The sea cucumber has the function of "splitting" like a starfish, in addition to the trick of discharging the organs and mesmerizing the enemy. The sea cucumber will be broken into several sections, put into the sea, after 3-8 months, each section will grow into a complete live cucumber.
Some sea cucumbers also have the ability to cut themselves, when the sea cucumber feels that the external environment is not suitable, it can cut itself into several segments, and then each segment will grow into a new individual. The barracuda can swim dozens of kilometers per hour, and when it attacks other animals, it is faster than an ordinary train.
Squid and octopus can suddenly spray water in front of them, and use the counter-thrust of water to quickly retreat. The squid is often referred to as a "cuttlefish", which can spray an ink-like substance into the water to blacken the surrounding sea water so that it can take advantage of the opportunity to escape.
Some shellfish don't move themselves, but they can travel underneath ships for free. Shellfish, also known as molluscs, are the most numerous of the shelled animals and the second most numerous in the animal world, with more than 75,000 living species.
The mouth (ventral) of the shell is turned downward, and the top of the shell is turned toward the observer, so that the end of the mouth of the shell is the front, the end of the top of the shell is the back, and the side located on the left side is the left, and the side on the right side is the right. Clockwise rotation of the shell is called right rotation, anti-clockwise rotation is called left rotation.
Pick up the shell, the top of the shell on the top, the mouth of the shell to the observer, to see which side of the shell opening in the screw axis. If the mouth of the shell is on the right side of the screw axis, then it is right-handed.
If it is on the left, it is left-handed. The lines on the surface of the shell are a true record of the growth environment and speed, and are a sign of the annual cycle of shellfish.
There are also some deep-water fish that have their own light-emitting organs and swim as if they were twinkling stars. Fish that can light up mostly live in the deep sea, shallow sea fish can light up less.
Fish rely on light-emitting organs on their bodies to emit light. These light-emitting organs are cleverly constructed.
Some have lenses, mirrors and filters that refract light; some have glandular cells that secrete light-emitting substances. There are also fish that glow because they are attached to ****-inhabiting luminescent bacteria, which emit bright light during metabolism.
Most fish have luminescent organs located on the sides of the abdomen, but there are also those that grow below the eye margins, dorsally, caudally, or at the ends of the antennae. In the shallow waters off the western coast of the Pacific Ocean, a small, clustered fish belonging to the toadfish family has about 300 luminaries on each side of its body that emit a strange glow.
In the sea near the Anglian Islands and Singapore Island, there is a small Baoyu 55 fish, its light-emitting organs are distributed around the digestive tract, due to the reflection of the swim bladder, this fish looks like the tungsten filament can not be seen in the milky white electric lamp. Living in the shallow Malayan sea lamprey perch, can emit white with green bright light, much like the moonlight reflected in the waves; here another lamprey, can emit a star-shaped light, looks as if the stars falling in the water.
Different fish emit different colors of bright light, and the same type of fish can emit different colors of light. The monkfish, which lives in the deep sea, has a light-emitting organ at the end of the first dorsal fin that emits light in red, blue and white colors, like a small lantern.
The lanternfish has two columns of luminous organs in its abdomen, the upper column emits red, blue and purple light, and the following column emits red and orange light. The light emitted by the fish is heatless and is cold light, also called animal light.
They glow for different purposes. The anglerfish glows to attract the opposite sex. A special and wonderful protection: the pine ball fish will emit a "curtain of light" to confuse the enemy, scare them and warn them when they are disturbed by the enemy.
More fish glow to illuminate the dark depths of the sea in search of food. The 36 Stratagems of Marine Animals: Vertigo The flat dorsal and abdominal, armored shrimp mayflies are very colorful and beautiful to look at.
It usually likes to live in the sandy shallow seabed, only to reveal its head to observe the enemy, once the prey is close, it will quickly stretch out the large chelae, "click" a prey in two, revealing its fierce, brutal face. Interestingly, shrimp mayflies are not only good at "strong attack", but also know "wisdom".
They often turn their own cave into a hidden place, and even go to great lengths to move from a distance to sand, stone in the residence of the sand cave next to the building of a few swinging channels, once the other animals intruded, as in a maze, self-inflicted. In the tropical coral reefs, there are spiny sea urchins.
Long spiny sea urchins are famous "sea thorns obscene", only the mouth around the spines, can be regarded as "undefended" area. But it grows on the bottom of the sea, lying on the rocks, other fish can not do anything about it, only smart scales can eat it.
The scales bite down on the tips of the long spines on the sea urchin, drag it from the bottom to the surface, and then release it. But as the urchin sinks, the scale swims underneath the urchin and attacks its mouth, eating all the flesh and guts of the sea urchin.
This method of hunting is very interesting indeed. In tropical waters, beautiful sea anemones often live with clownfish***.
Clownfish are not ugly, they are beautiful, colorful, dressed up, usually around the anemone back and forth to attract the attention of other fish. When other fish come to attack, the clownfish will quickly drill people in the anemone bush, the oncoming enemy fish immediately anesthetized by the anemone with poisonous tentacles, to become its mouth meal, the clownfish took the opportunity to share together.
This is their long-established *** raw relationship. Plants: 1. Make your own (autotrophic): scientists have found organisms on the seabed at over 10,000 meters.
In such a deep seabed, there is a huge water pressure, and due to the volcanic eruption on the seabed, making the temperature up to more than 300 degrees at the same time accompanied by volcanic eruptions a lot of sulfur (chemical) overflow. It is by using these substances that the sulfide bacteria are able to obtain energy to survive.
