Information on the hand-written newspaper of simple drawings of the underwater world: types of underwater creatures

After decades of investigation by marine science and technology workers According to research, 20,278 species of marine life have been recorded in the waters under my country’s jurisdiction. These marine creatures belong to 5 biological kingdoms and 44 biological phyla. Among them, the animal kingdom has the most species (12,794 species), and the prokaryotes kingdom has the least species (229 species). my country's marine life species account for about 10% of the world's total marine life species, and their quantity accounts for 50%.

Marine life in my country's seas can be roughly divided into two categories: marine life in waters and marine life in tidal flats according to their distribution. Among aquatic marine life, fish, cephalopods (such as the squid we often eat, also called cuttlefish), shrimps and crabs are the most important marine life. Among them, fish have the largest variety and quantity, constituting the main body of marine life in the waters.

The distribution trend of the number of marine life species in the waters is more in the south than in the north, that is, there are more species in the South China Sea, while there are fewer species in the Yellow Sea and the Bohai Sea. According to the latest survey data, there are more than 1,580 species of marine life distributed on my country's tidal flats. Among them, molluscs (what we usually call shellfish) are the most numerous, with 513 species, followed by seaweeds with 358 species, crustaceans (mainly what we usually call shrimps and crabs) with 308 species, and other groups with very few species. The number of species of organisms on my country's coastal tidal flats, like those in the sea, also gradually increases from north to south.

Scientists around the world are engaged in an unprecedented collaborative effort to identify and catalog all marine life. How many kinds of creatures are there in the ocean? A survey report combining global ocean data has been released. There are 15,304 species of marine fish that have been registered, and it is expected that there will eventually be about 20,000 species of marine fish. There are 210,000 known species of marine life, and the actual number is estimated to be more than 10 times that number, or 2.1 million species.

The project scientists are conducting is called the Census of Marine Life. It is expected to take 10 years and cost at least US$1 billion. ***More than 300 scientists from 53 countries are participating This unprecedented collaboration allows marine scientists from every corner of the world to work together. Since 2000, an average of three new marine species have been discovered every week. The research program estimates that there are approximately 5,000 species of marine fish and thousands of other diverse marine species that have yet to be discovered.

The census hopes to assess the diversity, geographical distribution and abundance of various marine organisms and explain how these changes over time. What is the practical significance of this plan? A census of marine life can identify endangered species and important breeding areas, and can help fishery management agencies develop effective continuous management strategies. And as thousands of new species of marine life are discovered, scientists will develop new marine pharmaceuticals and industrial compounds.

Frederick Glassel of Rutgers University in the United States, chairman of the Census of Marine Life Scientific Committee, said: "This is the beginning of the first great journey of discovery in the 21st century.

What's more, this is the first global effort to measure a variety of marine life and inform us of what we should be doing to prevent continued loss of marine life. "The ocean is still an unexplored territory, and we know very little about the organisms it supports." Ronald Dore, chief scientist of the Census of Marine Life, said: "The diversity of marine life is not only an important indicator of ocean conditions, but also an important indicator of ocean conditions. It is also the key to protecting the marine environment. ”

Underwater world simple drawing manuscript information: Marine reptiles

Overview

Reptiles are cold-blooded animals covered with horny scales and breed on land. . Among them, there are 24 species of sea turtles and sea snakes related to the sea.

Red Starfish

A starfish stretches out its hand, The red starfish is one of the most beautiful of the Galapagos Island marine creatures. The Fromia species come in many colors and shapes, with obvious knobs or spines on the body surface and many small holes on the back surface of the body disc. >Sea snakes

Sea snakes are venomous snakes that live in seawater all their lives. Sea snakes have upward-facing nostrils with valves that can open and close. After inhaling air,

they can close their nostrils and dive into the water. 10 minutes. The surface of the body is covered with scales, and there is thick skin underneath the scales to prevent the penetration of sea water and the loss of body fluids. The salt glands under the tongue have the function of expelling excess salt that enters the body with food. Half a meter, sea snakes can reach about 3 meters. They live in coastal waters, especially in brackish water estuaries, and except for a few sea snakes that lay eggs, they all give birth to eggs.

There are 19 species of sea snakes in my country, which are widely distributed in the coastal waters of Guangdong, Guangxi, Fujian, Taiwan, Zhejiang, Shandong, Liaoning and other provinces. The common ones are the green-ringed sea snake, the flat-chinned sea snake and the long-snouted sea snake. For medicinal purposes, it has the effects of dispelling wind and relieving pain, promoting blood circulation, nourishing and strengthening the body.

Sea turtles

Sea turtles are the general name for marine turtles that live in our country's oceans. There are 5 species (there are only 7 species in the world), mainly distributed in the Xisha Islands and the port of Huidong County, Guangdong Province, followed by the coastal areas on the outskirts of Sanya and Lingshui County, Hainan Province. The sea turtles recorded in the China Sea include leatherback turtles and sea turtles. 5 species, including turtles, turtles, hawksbill turtles and olive turtles, are all nationally protected animals.

Sea turtles are the largest reptiles in the marine world. The largest one is the leatherback turtle. With a maximum body length of 2.5 meters and a weight of about 1,000 kilograms, it is called the king of sea turtles.

The ancestors of sea turtles appeared on the earth more than 200 million years ago. The dinosaurs experienced a prosperous period together. Later, the earth went through great changes, the dinosaurs became extinct one after another, and the sea turtles also began to decline. However, the sea turtles relied on the protection of their hard carapace to defeat what nature had brought to them. Sea turtles have endured countless misfortunes and survived over a long historical journey of more than 200 million years. They are still surviving and reproducing from generation to generation. They are truly ancient, tenacious and precious animals. .

Underwater World Simple Drawing Handwritten Newsletter: Marine Plants

In the vast and rich ocean, in addition to all kinds of animals, there are also a wide variety of animals. Marine plants. Seaweed is the main body of marine plants and a natural wealth for mankind. There are more than 100 kinds of marine algae that can be used as food. Scientists divide seaweed into two major types: phytoplankton and benthic algae based on their living habits.

Pytoplankton

The algae of phytoplankton is composed of only one cell, so it is also called marine unicellular algae. This type of organism is a group of autotrophic organisms that have chlorophyll, can perform photosynthesis, and produce organic matter. They are the most important primary producers in the ocean, and are also the feed for farmed fish, shrimp, and shellfish. 1,817 species of phytoplankton have been recorded in the China Sea.

The motility of phytoplankton is very weak and can only float with the current or be suspended in the water for very weak floating. They come in a variety of body shapes adapted to a floating life, resulting in increased buoyancy. For example: some phytoplankton cells have a ring of stinging hairs around them; some have long spines or protrusions. These appendages increase the contact surface with water and can produce great stability, allowing them to float on the water. In light surface water; some form groups to expand the surface area for floating, and they themselves are very small, which is also a good adaptation to floating life.

The body diameter of phytoplankton is generally only a few thousandths of a millimeter. Their appearance can only be seen under a microscope, but their shapes have their own characteristics and are almost the same. Most of them are single cells, and many are groups of single cells. They are spindle-shaped, fan-shaped, star-shaped, oval, oval, cylindrical, and dendritic.

Benthic algae

Scientists call the algae that live on the seabed called benthic algae. They can adapt to temporary droughts and temporary "freezes" in winter during low tide. As soon as the sea tide rises, they will begin to grow and develop normally again. Benthic algae are mostly multicellular algae that can be seen with the naked eye. The adults of small species are only a few centimeters long, such as thread algae; the longest ones can reach 200 to 300 meters, such as macroalgae.

The shapes of benthic algae are strange: some are like ribbons, such as kelp; some are like ropes, such as rope algae; some are flake-shaped, such as Ulva and Porphyra; some are like branches, such as Sargassum.

Some benthic algae have only one thin layer of cells, such as reef membrane; some have two layers of cells, such as Ulva; some are hollow and tubular, such as Enteromorpha; and The algae can be divided into outer cortex, cortex and pith, such as kelp and sargassum.

The colors of benthic algae are bright and beautiful, including green, brown and red. Scientists divide seaweed into three major categories based on their color: green algae, brown algae and red algae.

Green algae

The algae of green algae are grass green. There are about 6,000 species of green algae, 90% of which are produced in freshwater, and only 10% live on rocks in the intertidal or subtidal zones. There are single-celled green algae, colonial ones, filamentous ones, and sheet-like ones. The most common marine single-cell green algae is Platyphylla, which is rich in protein and is a good feed for small animals in the ocean. The most common multicellular green algae include Ulva and reef membrane (called sea spinach or sea cabbage by coastal fishermen in my country), which are popular marine economic vegetables; and Enteromorpha, which can be used to make Enteromorpha cake with a delicious taste. Very delicious. In addition, there are feather algae, bracken, spiny sea pine, umbrella algae, etc.

Coelenterata, also known as Cnidaria.

Stony coral, gorgonian coral, red coral, sea anemone, jellyfish, jellyfish, hydrozoa, molluscs. Such as oysters, abalone, pearl oysters, scallops, clams, clams, sea red (mussels)

Chiton phylum.

Such as prawns, lobsters, crayfish, krill, pipe whip shrimp, red shrimp, eagle claw shrimp, hedgehog shrimp, drum shrimp, long-arm shrimp, macrobrachium, rice shrimp, mole cricket shrimp, beauty shrimp , cicada shrimp, mysid shrimp, gammarid shrimp, armored shrimp, chordate phylum vertebrate subphylum. Marine fish such as sharks, whale sharks, basking sharks, hammerhead sharks, sawfish, fan rays, and electric rays, cephalopods, are marine carnivores. It includes major economic species such as cuttlefish, calamari, soft fish, and octopus.

The turbid sea - the Yellow Sea.

The Yellow Sea is due to the inflow of the Yellow River. The river water carries a large amount of sediment, and the seawater has more suspended matter, making the water less transparent. Therefore, the name of the Yellow Sea came into being. The Yellow Sea is the coastal defense base of northern China and the main road in North China. The warm currents of the Yellow Sea converge and the aquatic products are abundant. In particular, the beaches of the Bohai Sea and the Yellow Sea are flat and vast, suitable for saline-alkali land.

Colorful molluscs

In the underwater world, there is a willingness to build "houses" among animals. They can secrete calcium from their bodies and use it as building materials to build "houses". Used as their own homes, these animals are shellfish. Because their bodies are soft, they are molluscs. The "houses" they build are those brightly colored shells. There are many kinds of molluscs, second only to arthropods in the animal kingdom. There are seven categories, namely, no plate, single plate, multiple plates, bivalve, gastropod, dipoda, and cephalopod. Except for plateless and veneer, the other five categories are distributed in the China Sea. Currently, there are 2,557 species of molluscs in China's oceans, accounting for more than 1/8 of the total number of marine species in China.

A variety of echinoderms

When you walk among the rocks and seaweed on the beach, you can see sea stars, sea urchins, sea cucumbers and other marine animals. The bodies of these animals have many spinous processes of varying lengths, so these animals are called echinoderms. The body structure of echinoderms is more interesting and radial, mainly characterized by five types of radial symmetry. Echinoderms are marine creatures that are found nowhere else on land or in fresh water. So far, about 600 echinoderms have been recorded in Chinese waters.

The starfish with multiple abilities

Starfish are important members of the echinoderms. The five-armed starfish is shaped like a five-pointed star. Its mouth is located on the oral surface (light or orange), and the anus is on the anti-oral surface (light-colored background with purple or dark brown markings). The starfish lies on its belly, with its five arms stretched out, and crawls leisurely on the sand or rocks in the shallow sea using a large number of tube feet (the starfish's moving organs). The starfish's unique skill is that it can be divided into two parts. If you tear a starfish into several pieces and throw them into the sea, each fragment will quickly grow back the lost parts, thus growing into several complete new starfish. Currently, scientists are exploring the mysteries of starfish's regenerative abilities in order to draw inspiration from them and seek a new medical method for humans.

Underwater World Simple Drawing Handwritten Information: The Ten Most Dangerous Undersea Animals

1. Box Jellyfish

In this Top Ten Most Dangerous Undersea Animals In the animal competition, the box jellyfish claimed the title of most dangerous due to its unique lethality. There are many species of box jellyfish that live in the ocean. Although there are no official records, there is a lot of anecdotal evidence that dozens or even more than 100 people are killed by box jellyfish every year.

2. Tiger shark

But the most terrifying shark is not the great white shark, but the tiger shark, and more people have actually died from their mouths. Except for venomous snakes, there are few animals that can make people naturally fearful, and sharks are one of them. Tiger sharks can be found in many tropical and temperate waters, especially around islands in the central Pacific. Records show that the number of great white shark attacks on people per year is indeed higher than that of tiger sharks, but the number of fatal accidents is lower than that of tiger sharks.

3. Stonefish

There are two main reasons why stonefish are among the top three: one is that they are the most poisonous fish in the world; the other is that they are It is a master of disguise in the animal kingdom. It can "lurk" on the seabed as quietly as a stone, waiting for prey to come to you. Although stonefish will not take the initiative to attack, no one dares to risk close contact with it. The spines on the stonefish's back protect it from attacks by sharks and other predators. The venom released can cause temporary paralysis, which can lead to death without treatment.

4. Pufferfish

There is an animal that can kill people even if it is made into delicacies and put on the table. It is the pufferfish. Puffer fish, also known as "air drum fish", carry toxins in their bodies that are more toxic than cyanide. Specially trained Japanese chefs will cook safe parts into delicacies, but tragedies in which diners are poisoned and die often occur.

5. Sea snakes

Human beings have a natural fear of snakes, and it is this fear that makes sea snakes easily included in the list. Although they release terrible venom like their land-based counterparts, sea snakes live more like a "marine hermit" and are therefore not very dangerous. Sea snakes are often compared to cobras when it comes to venom. The venom they release can paralyze and ultimately kill their prey in just seconds. Fortunately, they rarely attack humans, preferring to hunt eels, shellfish, and shrimp.

6. Lionfish

Lionfish, also known as "lion fish", is a popular pet in domestic fish tanks. This fish may seem docile, but its fan-shaped spines are also surprisingly venomous. The National Oceanic and Atmospheric Administration says that although it won't cause fatal injuries to humans, being stung by the thorns can cause headaches, vomiting and difficulty breathing, so it's definitely not a guy to mess with.

7. Crocodile

Saltwater crocodiles have always been known as "one of the most ferocious predators in the wild animal kingdom". They can grow to more than 20 feet (about 6 meters) in length and weigh up to 3,000 pounds (about 1,360 kilograms). They hunt animals including monkeys, kangaroos, buffalo and even sharks.

8. Stingrays

Stingrays are commonly known as "stingrays". From this name alone, it is not difficult to guess that they are a very dangerous animal. In 2006, "Crocodile Hunter" Steve Irwin died after being stabbed in the heart by a stingray. Irving's misfortune undoubtedly enhanced the reputation of stingrays, a close relative of sharks, as "dangerous animals."

9. Sea lions

The reason why sea lions are among the top ten most dangerous marine animals is that they are very territorial and will never treat trespassers. Show mercy. Known as intelligent and trainable animals, sea lions are big stars in zoos, but they are also known in the animal world for their biting behavior.

10. Moray eel

Moray eel has a snake-like body, a protruding snout and a wide jaw. They are members of a family of fish that can reach up to 8 feet in length. Looking at this relatively primitive animal, we naturally associate it with death. The National Oceanic and Atmospheric Administration states that moray eels have powerful jaws and sharp teeth, and the jagged wounds caused by bites can easily be infected by bacteria in the moray eel's mouth.

Underwater World Simple Drawing Handwritten Newspaper Information: Undersea Creatures

There are creatures almost everywhere in the ocean, but different environments, species composition and structure of biological communities, and various groups The number, individual size, morphology, physiological and biochemical characteristics, etc. are all very different. The distribution pattern of marine life interacts with the marine environment and evolves in coordination. Marine organisms are generally divided into three categories: plankton, nekton, and benthic organisms based on lifestyle.

Plankton

No swimming or weak swimming ability, water movement suspended in the water, including bacteria, phytoplankton, zooplankton (such as diatoms, dinoflagellates, etc.) and ( Soft bodies such as jellyfish, pteropods, different species of animals, larvae of many marine animals, etc.). Most plankton, called permanent plankton; some plankton at a certain stage of life, called stage plankton, such as the larvae of many marine animals; there are also some primitive non-plankton, which occur in plankton , such as some low-level crustaceans, and small shrimps called temporary plankton. Phytoplankton can only live in the light water layer; zooplankton does not, and some can live in deep water below a thousand meters, and most can move vertically in the water. Plankton generally have low body weight (light shell, high body fat content, full of mucus), large sinking resistance (relatively large body, surface stings, bulges, and even blocks) or movement of cilia and flagella, and have certain abilities.

Swimming creatures

It refers to animals that have developed locomotive organs and have strong swimming ability. Including fish, mammals such as whales, dolphins, seals, reptiles such as sea snakes, turtles, molluscs such as squid, octopus, etc., as well as large shrimps such as shrimps and lobsters, their swimming, speed and speed are also very large difference. Some species can travel long distances across the ocean, like tuna; some swim very fast, like swordfish, which can reach speeds in excess of 70 kilometers per hour. Eels move with their entire bodies, and squid and octopuses spurt water from funnels to propel their bodies backwards.

They sometimes live in the upper waters (such as Pacific herring), and some live in the middle or lower waters (such as small yellow croaker, red snapper and salmon). In addition to the well-developed swimming organs, most of the body is streamlined to reduce drag and increase swimming speed.

Benthic organisms

A variety of organisms that live at the bottom of ocean waters and cannot swim in the water for a long time, including benthic plants (almost all macroalgae and seed plants such as mangroves) ), benthic animals (there are benthic species in sponges, coelenterates, annuli, linear, software, crustaceans, echinoderms, vertebrae and other categories). Benthic organisms can be divided into three major types of life based on their relationship with the substrate: on the bottom, on the bottom, and on the bottom; there are also intertidal organisms on the shore.

Both organisms

Live on the hard seabed. Including sessile life on various substrates (such as sea anemones, hydra, barnacles, oysters, ascidians), attached life (such as purple mussels, attached diatoms, macroalgae) and crawling on the seabed (such as horse dung, sea urchins, sea ??cucumber and red snail, etc.) animals. Animals that live sedentary have degenerated locomotor organs but developed tactile organs and feed passively. The larvae live a planktonic life and rely on sea currents to expand their distribution area. Organisms that are fixed or attached to the bottom of ships, buoys, factory sewage pipelines, offshore oil platforms and other offshore facilities are called fouling organisms (including microorganisms, algae and animals). They are harmful to transportation, military and production.

Bottom organisms

Live in soft sea bottom. Some secrete sticky substances to form tubes or use secretions to bind sedimentary particles to form tubes and inhabit them (such as nesting nereid, phosphorus nereid, etc.); some have developed digging organs and bury their bodies in the sand (e.g., yellow worm) Island acorn worms, Chinese clams, amphioxus, etc.); some drill wood (such as shipworms) and stone (such as corrugated groove sea bamboo shoots).

Benthic organisms

Have certain movement abilities and can move slowly on the bottom of the water (such as swimming crabs).

Intertidal organisms

A special type of benthic organisms. After long-term evolution, benthic organisms have good adaptability to the rise and fall of tides, the impact of waves, sunlight exposure, temperature changes, etc. Due to the differences in ecological niches in the intertidal zone, the distribution of organisms in the intertidal zone is very regular and the community structure is relatively clear.

Underwater World Simple Drawing Handwritten Information: Types of Seabed Resources

The seabed includes international seabed areas and continental shelf areas under the jurisdiction of some countries (including legal continental shelves). The strategic position of the deep sea is rooted in its vast space and rich resources. Deep seabed resources include:

(1) Polymetallic nodules distributed on the seafloor at a water depth of 4,000 to 6,000 meters and rich in copper, nickel, cobalt, manganese and other metals.

(2) Cobalt-rich crusts distributed on the surface of seamounts and hydrothermal polymetallic sulfides distributed in mid-ocean ridges and fault active zones.

(3) The protection and utilization of biological communities living in deep-sea hydrothermal vent areas and seamountain areas have attracted great attention from the international community due to their special living environment.

(4) The total amount of natural gas hydrates mainly found on the edges of continents is about 1.8-2.1 Times, it is considered to be a new energy source with great potential that can be developed in the 21st century. The deep sea will become a strategic development base for a variety of natural resources in the 21st century, and may form a deep sea industry cluster including deep sea mining, deep sea biotechnology, deep sea technology equipment manufacturing and other industrial categories. The rapid development of knowledge about deep seabed resources over the past few decades will not only significantly increase the world's resource base, but may also bring considerable economic benefits to the world's future. The newly discovered resources are mostly on the international seafloor beyond national jurisdiction, and some are richer than any land deposits. To this end, the International Seabed Authority, which organizes and manages exploration and development activities in the international seabed area, is working on the formulation of relevant regulations. The Authority adopted regulations for prospecting and exploration for polymetallic nodules in the international seabed area in 2000 and is currently developing a similar set of prospecting and exploration regulations for polymetallic sulphides and cobalt-rich crusts.

Underwater World Simple Drawing Handwritten Newspaper Information: The Secret of Undersea Bioluminescence

Whenever night falls on the sea, people can often see the twinkling lights on the sea surface like tongues of fire. . Ocean luminescence is mainly caused by luminescent bacteria. In the organisms of these luminescent bacteria, a luciferin combines with oxygen to form oxyluciferin. The energy generated by the chemical reaction is released in the form of light, thus emitting light. Marine luminescent bacteria mostly live in tropical and temperate oceans. Most of them grow on fish, shrimp, shellfish, algae and other organisms in a parasitic, saprophytic or saprophytic manner, providing new light sources for these fish, shrimp, shellfish, etc., making them more conducive to foraging and Drive away enemies. The light emitted by a melon jellyfish allows people to see people's faces clearly in the dark; the light emitted by the water flea is also very powerful, and its light can be used to read newspapers on the deck of a ship.

In addition to luminescent bacteria, many fungi, crustaceans, insects, and seabirds emit bioluminescence. In the swamps of Africa, there is a kind of glowing crow. Its head is covered with a glittering hard shell. Its brightness is equivalent to the brightness of a two-watt light bulb. The local residents catch this crow and keep it in the bird house. In the cage, it is used as a flashlight when walking at night.

The light emitted by sea aquatic organisms is "cold light". While emitting light, there is no consumption of radiant heat energy, so the efficiency of bioluminescence is very high. When an ordinary light bulb (incandescent lamp) is powered on, the hot tungsten filament turns about 7%-13% of the electrical energy into visible light, and the rest of the electrical energy becomes invisible light and heat. Biolight can convert chemical energy into visible light almost 100%, which is several to dozens of times more efficient than ordinary electric light sources. For a long time, people have cleverly used this kind of biological light to benefit themselves. For example, fishermen use sea light to find fish schools and identify reefs, shoals, sandbars and icebergs. Since the biological light source has no current and does not generate a magnetic field, people can do work such as eliminating magnetic mines under the illumination of this light flow. With the development of science and technology, the wonderful biological luminescence will be further understood by people. One day, cold light will be applied on a large scale, and various luminous walls or cold light luminous bodies that do not radiate heat will be born one after another, which will surely cause a great change in people's living areas.
