Most river mammals spend only part of their lives in water. Animals such as the river otter and the swimming rat live on land and venture into the water in search of food.
1. Hippopotamus.
A hippopotamus peers out of an algae-covered lake in Kenya's Masai Mara Game Reserve. These massive mammals cool their huge bodies in African lakes, ponds and rivers for up to 16 hours a day every day. And although these animals can hold their breath for about half an hour, they usually do not submerge completely under water, leaving the top of their heads on the surface. At night, hippos leave the water and come to land in search of food. If they stay on land too long during a hot day, the animals quickly become dehydrated.
2. Hippopotamus.
The Zambian hippopotamus sends an aggressive message by displaying its sharp teeth, which can reach lengths of 20 inches (51 centimeters). Males use a wide open mouth when fighting to determine which animal is dominant. Sometimes a simple show of force is not enough, and such behavior leads to potentially deadly battles. Hippos are also dangerous to humans.
3. Manatee.
Manatees swim slowly through shallow, warm coastal waters and rivers. For example, such as this crystal clear river in Florida - Crystal River, which is shown in this photo. The large mammals (up to 1,300 pounds or 600 kg) are born underwater and remain there throughout their lives, although they must come up for air every few minutes. Known as sea cows, they are voracious herbivores, feeding on a variety of sea grasses, weeds and algae.
Some various types Manatees live along the Atlantic coast of North and South America, the west coast of Africa, and in the Amazon River.
4. Muskrat.
Muskrats are frequent inhabitants of wetlands, swamps and ponds, where they make their burrows by digging tunnels in marshy banks. This large rodent has a foot-long body and a flat tail almost as long as its body. Muskrats are well adapted to water and begin to swim 10 days after birth. Perhaps best known for their highly developed communication skills, muskrats exchange information with each other and ward off predators with their distinct scent.
5. Baikal seals.
There are a large number of seals living in the world, but only one species is truly freshwater - the Baikal seal. These seals live in the lake of the same name in the territory Russian Federation, which is the deepest in the world. Although new generations of Baikal seals are born every year in such colonies, this species is not in serious danger. The main threats are poaching, as well as pollution from paper and pulp production, which are located near the lake.
6. Amazonian dolphin.
To track food (small fish and crustaceans) in murky river waters, the charismatic Amazon dolphin uses echolocation. During their annual leashes, these dolphins actually swim through the flooded forests and hunt among the trees. The bright hue (often pink or very pale) and natural curiosity of this dolphin species make them easy targets for fishermen poachers who illegally catch them to use as catfish bait. The population of these individuals has decreased significantly over last years. Among the locals inhabiting the shores of the Amazon, these dolphins have long been considered supernatural creatures that could take on human form.
7. Capybara.
The world's largest rodent, the capybara grows to 4 feet in length (130 cm) and weighs about 145 pounds (66 kg). These moisture-loving mammals reach this size by eating grasses and aquatic plants.
In most cases, these mammals live in watery areas, to which they are physically well adapted. They have webbed feet, thanks to which they swim well and can dive under water for five minutes or more. Capybaras live in Central and South America, inhabiting the lakes, rivers and wetlands of Panama from southern Brazil to northern Argentina.
The Nature Conservancy is working with partners to protect capybara habitat, including the watery grasslands of Llanos. The group is working with local landowners to create private reserves in critical habitat areas and helping to secure more resources for a 63,000-acre (25,500-hectare) conservation area in Casanare province in northeastern Colombia.
8. Capybaras.
The eyes, ears and nostrils of capybaras are located high on the head, so they remain on the surface when the animal is in the water. These social mammals move and live in alpha male-dominated groups and work together to defend their home and feeding territory. People hunt (and also farm) capybaras for their skin and meat, which is especially popular during Lent - Catholics in South America consider the animal an acceptable alternative to beef or pork.
9. Beaver.
Beavers are ecological engineers, second only to humans in their ability to significantly alter the landscape to their liking. Using their powerful jaws and teeth, they cut down trees by the dozens and build dams of wood and mud 2 to 10 feet (1-3 meters) high and over 100 feet (30 meters) long. And they do this so that the filling waters flood the nearby fields and forests. In the resulting lakes, which are sometimes enormous in size, beavers build their homes from branches and mud.
10. Beaver.
Although they are quite clumsy on land, beavers swim easily in the water thanks to their webbed feet and paddle-shaped tail, which help them reach speeds of up to 5 miles (8 km) per hour. These mammals also boast a sort of natural diving suit in the form of their oily, water-resistant fur.
Beavers eat aquatic plants, roots, leaves, bark, and branches. Their teeth grow throughout their lives, so they simply need to chew on trees to prevent them from growing too long and crooked. A single beaver chews down hundreds of trees each year, typically gnawing down a tree 6 inches (15 cm) in diameter in just 15 minutes.
11. River otter.
This sleepy river otter is actually very playful. The water-loving mammal is always willing to dive under water and can move gracefully thanks to its webbed feet and paddle-shaped tail. Otters have specially designed ears and nostrils that close underwater, as well as water-repellent fur. Young otters begin to swim at the age of 2 months. River otters live in burrows along the edges of a river or lake in close proximity to the fish on which they feed.
12. Platypus.
The platypus is an incredible mixture of different animals: its furry body resembles that of an otter, its beak like that of a duck, and its webbed feet and paddle-shaped tail like a beaver. Like all these animals, the platypus is a strong swimmer and spends most of its life underwater. Unlike otters and beavers, they lay eggs. Male platypus have poisonous stings on hind legs. These animals build their burrows at the very edge of the water and feed on underwater worms, mollusks and insects.
An animal that lives in water for a period of time or its entire life. Many insects, such as mosquitoes, mayflies, dragonflies and caddisflies, begin their life cycle as aquatic larvae before developing into winged adults. Aquatic animals can breathe air or obtain oxygen dissolved in water through specialized organs called gills or directly through the skin. Natural conditions and the animals that live in them can be divided into two main categories: aquatic or.
Groups of aquatic animals
Most people only think of fish when asked about aquatic animals. However, there are other groups of animals that live in water:
- mammals, for example (whales), sirenians (dugongs, manatees) and pinnipeds (seals, eared seals and walruses). The concept of "aquatic mammal" also applies to animals with a semi-aquatic lifestyle, such as river otters or beavers;
- shellfish (eg sea snails, oysters);
- (for example, corals);
- (eg crabs, shrimp).
The term "aquatic" can apply to animals that live in both fresh water (freshwater animals) and salt water (marine animals). However, the term marine organisms is most often used for animals that live in sea water, that is, in the oceans and seas.
Aquatic fauna (especially freshwater animals) are often of particular concern to conservationists due to their fragility. They are exposed to overfishing, poaching, pollution, etc.
Frog tadpoles
Most are characterized by an aquatic larval stage, for example, tadpoles in frogs, but adults lead a terrestrial lifestyle near bodies of water. Some fish, for example, the arapaima and the walking catfish, also breathe air to survive in oxygen-poor water.
Do you know why the hero of the famous cartoon "SpongeBob SquarePants" (or "SpongeBob Square Pants") is depicted in the form of a sponge? Because there are aquatic animals called marine animals. However, sea sponges do not look like a square kitchen sponge like the cartoon character, but have a more rounded body shape.
Fish and Mammals
School of fish near a coral reef
Did you know that there are more species of fish than amphibians, birds, mammals and reptiles combined? Fish are aquatic animals because their entire lives are spent in water. Fish are cold-blooded and have gills that receive oxygen from the water to breathe. In addition, fish are vertebrates. Most fish species can live in either fresh or saltwater, but some fish, such as salmon, live in both environments.
Dugong is an aquatic mammal from the order of sirens.
While fish live only in water, mammals can be found on land and in water. All mammals are vertebrates; have lungs; They are warm-blooded and give birth to live young instead of laying eggs. However, aquatic mammals depend on water to survive. Some mammals, such as whales and dolphins, live only in water. Others, such as beavers, are semi-aquatic. Aquatic mammals have lungs but no gills and are unable to breathe underwater. They need to come to the surface at regular intervals to breathe air. If you've ever seen what a fountain of water looks like coming out of a whale's blowhole, it's an exhalation followed by an inhalation before the animal dives back underwater.
Molluscs, cnidarians, crustaceans
The giant tridacna is the largest representative of bivalve mollusks
Molluscs are invertebrate animals that have soft, muscular bodies without legs. For this reason, many shellfish have a hard shell to protect their vulnerable bodies from predators. Sea snails and oysters are examples of shellfish. Squids are also classified as mollusks, but they do not have shells.
Swarm of jellyfish
What do jellyfish, sea anemones and corals have in common? All of them belong to cnidarians - a group of aquatic animals that are invertebrates and have a special mouth and stinging cells. The stinging cells around the mouth are used to catch food. Jellyfish can move around to catch their prey, but sea anemones and corals are attached to rocks and wait for food to approach them.
Red crab
Crustaceans are aquatic invertebrate animals with a hard chitinous outer shell (exoskeleton). Some examples include crabs, lobsters, shrimp and crayfish. Crustaceans have two pairs of antennae that help them receive information about their environment. Most crustaceans feed on the floating remains of dead plants and animals.
Conclusion
Aquatic animals live in water and depend on it for survival. There are various groups of aquatic animals, including fish, mammals, molluscs, cnidarians and crustaceans. They live either in freshwater bodies (streams, rivers, lakes and ponds) or in salt water (seas, oceans, etc.), and can be either vertebrates or invertebrates.
There are many natural bodies of water: ponds, lakes, seas and oceans. But rivers and streams cannot be called reservoirs - they are water streams. There are many different fish in rivers and reservoirs: crucian carp, catfish, carp (also known as carp), bream, gudgeon, sturgeon, pike, perch, cod and many others.
The appearance and behavior of fish depend on their living conditions.
All predatory fish have large heads with large mouths armed with sharp teeth. Non-predatory fish eat worms, crustaceans, algae, they have a small mouth - they do not need to swallow other fish.
Catfish is a predatory fish that swims near the bottom, looking for food. Its abdomen is flat, its back is convex, its large mouth is surrounded by antennae. His eyes are small. The color is grayish-yellow with spots, matching the color of sand and pebbles at the bottom of the reservoir.
Pike is also a predatory fish, it has a large head, a large mouth and sharp teeth. She spends a lot of time in ambush, standing in one place and waiting for prey. Seeing a fish, it quickly swims out of its hiding place and grabs it. When the pike is near the surface of the water, it catches midges and mosquitoes falling into the river, sometimes even jumping out of the water to do this. Therefore, its mouth is directed upward, its back is flat, its body is flattened.
In winter, during severe frosts, a strong ice roof appears above the fish’s heads—ice. Pisces usually sleep in winter. Crucian carp and tench burrow into the silt at the bottom of reservoirs; minnows and bleaks winter in depressions with a sandy bottom; carp and bream hide in deep holes overgrown with reeds; sturgeons gather in tight heaps at the bottom, where the water does not freeze. After all, the deeper the water, the warmer it is. By the end of winter, fish begin to run out of air. Gasping and convulsively opening their round mouths, they rise to the surface, grabbing air bubbles with their lips. To enrich water with oxygen, people make ice holes in ponds, rivers and lakes. Near them on the ice you can often see fishermen engaged in ice fishing.
By spring, all the fish wake up and begin to spawn - to spawn. To do this, they find secluded places so that the eggs cannot be eaten by other fish and animals. Over time, fry appear from the eggs, very small, gray, transparent. They are almost invisible in the water, but many of them still die when they get into the mouths of fish. The surviving fry grow and become adult fish.
Some fish do not spawn; they will give birth to live fry. Children can see their birth by watching the fish in the aquarium (guppies, barbs).
Flying fish live in some large bodies of water. Fleeing from predators, they jump out of the water and fly about three to five meters. In the seas and oceans, they can fly through the air up to two hundred meters, while they flap their fins like wings. There are known cases when fish flew onto the decks of passing ships.
In addition to fish, many different animals live in rivers and other bodies of water: snails, collecting food, crawl along the bottom and plants, and hide from enemies in a house - a hard shell; crayfish move not forward, but backward, pushing off with two claws and leaning on their tail. They are dark in color, matching the color of the river bottom. People learned to catch them, as crayfish meat is very tasty. If you pick up a crayfish carelessly, it may pinch your hand painfully with its claws. Boiled crayfish take on a bright red color.
Frogs can live in water and on land; jumping on the grass, they catch insects with their tongue. Frogs are very timid: when they hear footsteps, they quickly jump into the water and dive into the depths. When everything calms down, they look out of the water and inspect the shore: if there is no one there, they go out onto land to warm themselves and catch midges.
Also in reservoirs there are leeches, water bugs, small crustaceans of daphnia (fish in aquariums are fed dry daphnia), etc.
Large animals live in the seas and oceans: dolphins, walruses, seals, squids. But the largest animal on earth that lives in water is the whale. Thirty elephants can fit on his back; but there are also small whales - two to three meters long. Whales breathe with their lungs, not their gills. They have an overgrown nostril in their nose, in which air is stored, like in a bag, so they can stay under water for two hours, after which they rise to the surface to take in a new portion fresh air, and then you can see many fountains above the sea. A whale's stomach holds two to three tons of food; whales swim at a speed of fifty kilometers per hour and dive to a depth of three kilometers. They give birth to live cubs that feed on their mother's milk. Whales live up to fifty years. The whale is a valuable animal: whalebone, skin, liver and fat are used in the manufacture of medicines.

Sample story about fish
Crucian carp is a non-predatory fish. His body is elongated, flattened laterally; there are pectoral, dorsal and caudal fins; His mouth is small and he breathes through gills. Covered with scales of an inconspicuous gray color, matching the color of the bottom and driftwood. Crucian carp spend whole days looking for food at the bottom of reservoirs, pulling worms out of the sand, catching water bugs, daphnia, and plucking small leaves in thickets of plants. Its enemy is the pike; it watches for prey in cover, so the crucian carp is always on the alert. Thanks to its narrow body, it can instantly wag its tail, bend its entire body and immediately disappear. In winter, he buries himself in the sand and sleeps. By spring it wakes up and swims to its favorite place to spawn.
People eat fried, salted, smoked and boiled fish; fish soup is called "ukha".

Rice. 2. Lake Arakul ()
Or artificial: pond, reservoir, canal (Fig. 4-6).
Rice. 5. Reservoir ()
Whatever the body of water, natural or artificial, it adorns our land and delights us with its beauty. We take water from fresh reservoirs, which we cannot do without either in everyday life or in production. We swim in bodies of water, sunbathe next to them, travel on ships on water, and transport cargo. The importance of reservoirs in nature is great. Fresh water is the most important condition for human existence on Earth, and for animals that live in water, it is also the only home. Water contains everything necessary for life: light, heat, air and dissolved minerals.
What plants grow and what animals live in fresh water bodies? Finding yourself near a reservoir in the warm season, you could only observe those of its inhabitants who live on the surface. But life in a body of water is everywhere: near the shores, on the surface, in the water column, at the very bottom and at the bottom. On the banks of reservoirs you can see leaves and stems of reeds, reeds, cattails, and arrowheads. The shallow depth allows these plants to attach to the bottom of the reservoir. At a much greater depth, white water lily and yellow water lily grow (Fig. 7, 8). Their flowers and wide leaves float on the smooth surface of the water.
Rice. 7. White water lily ()
Rice. 8. Yellow egg capsule ()
How did these plants manage to adapt to life in highly moist soil, where there is almost no oxygen? If you examine a section of the stems of reeds, reeds, and cattails, you can see the air channels that run in the stems of these plants (Fig. 9, 10).
Rice. 9. Reed ()
There are air channels in both the leaves and roots of aquatic plants. In the white water lily and the yellow water lily, the petioles of the leaves and the peduncles on which the flowers sit are also pierced with air channels through which the oxygen necessary for breathing penetrates. By picking a flower, a person harms the entire plant. At the site of the rupture, water begins to penetrate into the plant, this leads to rotting of the underwater part and, ultimately, the death of the entire plant.
Duckweed grass in the form of small green plates also floats on the surface of the reservoir, but is not attached to the bottom by its roots, and in the water column there are tiny green algae, which can only be seen under a microscope. But their presence reveals the color of the water. When there are a lot of them in a reservoir, the color of the water turns green.
What role do plants play in the lives of numerous inhabitants of water bodies? Firstly, green plants, under the influence of sunlight, take carbon dioxide from the air and release oxygen into the water, which is necessary for the respiration of all animals. Secondly, birds, amphibians, insects and their larvae, and fish find shelter and food in the thickets of a reservoir. Animals are everywhere in reservoirs: on the surface and in the water column, on the shore, at the bottom, on aquatic plants. The main connections between animals and plants are food. Here water striders (Fig. 11) quickly run along the surface of the water and hunt mosquitoes and other small animals.
Rice. 11. Water strider ()
Their long legs The bottom is covered with fat, which is why the water holds them. And snails live on aquatic plants: pond snail and coil (Fig. 12, 13).
Rice. 12. Prudovik ()
Without whom the river cannot live? Very small crustaceans of reservoirs, daphnia and cyclops, live and winter in water. Their value is slightly larger than the decimal point in the book (Fig. 14, 15).
The most remarkable thing about daphnia is its long mustache. They will wave their mustaches, lower them sharply, push off from the water and jump. The Cyclops has an unpaired frontal ocelli, from which it gets its name.
The river cannot live without crustaceans, since they purify the water from bacteria, green algae and tiny animals invisible to the eye; if not for the crustaceans, the river would quickly overflow with them. Daphnia and cyclops, like other inhabitants of the river, feed on these organisms, thereby purifying the water. They themselves serve as food for fish fry, mollusks, tadpoles, and insect larvae.
Is there really someone living in the river without a head? These are mollusks, toothless and pearl barley (Fig. 16).
Rice. 16 Clams ()
At first, the shell, consisting of two longitudinal plates, will lie motionless, then its doors will open slightly and a leg will stick out of it; neither the toothless nor the barley has a head. Toothless will extend his leg and stick it into the sand, the shell will move. The toothless one will move 2-3 centimeters, rest, and then hit the road again. This is how it travels along the bottom of the river. The toothless fish obtains food and air directly from the water. It opens the shell doors slightly and begins to draw in water, then throws it out. The water is full of tiny animals, they fall into the sink, and the toothless fish uses special devices to stop them. The toothless one breathes and eats, and at the same time purifies the water. And pearl barley also works. Each one purifies approximately 40-50 liters of water per day. Mollusks, insect larvae, and tadpoles are eaten by fish, storks, waders, and ducks. The swimming beetle preys on other insects, as well as worms, snails, and tadpoles. Frogs feed in the coastal parts of reservoirs, mainly on flying insects, and they themselves are food for newts and predatory fish, perch and pike. Herons, gulls, and kingfishers hunt for fish and newts.
The main food of cancer is plant-based. But he willingly eats animals, as well as the remains of dead animals. Therefore, crayfish are often called the orderlies of reservoirs (Fig. 17).
Crayfish change their shells throughout their lives. The sense organs of crayfish are perfectly developed, the eyes are pushed forward on thin stalks and consist of a huge number, 3000, of tiny eyes. A short pair of antennae are the organs of smell, and long ones are the organs of touch. If a predator grabs a crayfish by the claw, the crayfish breaks it off and hides in a hole. A lost claw will grow back. Crayfish are very sensitive to water pollution, so in places where they are found, they talk about the ecological cleanliness of water bodies.
Near the river you can see different dragonflies: the beauty, the arrow, the lute; they live near the river constantly (Fig. 18).
Rice. 18. Dragonfly ()
All dragonflies need water because that is the only place their larvae can live. The larvae are not similar to adult dragonflies, only their eyes are the same. Each eye consists of almost 30,000 tiny ocelli (Fig. 19).
Rice. 19. Dragonfly larva ()
Both eyes are convex, thanks to which the dragonfly can look in all directions at the same time (Fig. 20). All dragonflies are predators; they hunt in the air and grab insects in flight.
Rice. 20. Dragonfly eyes ()
The dragonfly larva, lying in wait for prey, throws forward its strongly elongated lower lip. Usually the lips are folded and cover the head like a mask. The larva sucks water into a large muscular sac inside the body and then forcefully throws it out. It turns out to be a water shot. After a year, and some after 3, the larvae emerge to the surface, the skin of the larva bursts, and a dragonfly emerges from it. It will sit for several hours, spread its wings and fly away.
Who lives in a drop of water? If you look through a microscope, it will open amazing world unusual creatures. Here is an almost transparent lump that changes all the time - this is an amoeba (Fig. 21).
Other creatures resemble tiny shoes, which is what they are called. The body of the shoe is covered with cilia, each skillfully controls these cilia and swims quickly (Fig. 22).
Rice. 22. Shoe ()
Trumpeters are the most beautiful inhabitants of the drop, blue, green, similar to bindweed flowers (Fig. 23).
The trumpeters move slowly and only forward. If something scares them, they shrink and resemble balls. Amoebas, slippers and whelks are single-celled organisms that feed on bacteria.
Predators also live in a drop of water. This is didinium (Fig. 24).
Although he is smaller than a shoe, he not only boldly attacks her, but also swallows her whole, swelling up like a ball.
Plants, animals, and bacteria live together in a fresh body of water, all of them are well adapted to life in water and are interconnected by food chains. When plants and animals die, they accumulate at the bottom of reservoirs, are destroyed by bacteria and turn into salts, which dissolve in water and are used by other animals. A body of water is a natural community.
Today in the lesson you gained a new understanding of a freshwater body as a freshwater community and became acquainted with its inhabitants.

Guys, today I would like to invite you to go on an exciting journey. Close your eyes, listen and find out where we are going. (An audio recording of the sound of a river sounds.)
What did you hear? (The sound of the river.) Today we will go traveling along the river in our area. Who knows what it's called river in our area? (Tashtyp.)
That's right guys river"Tashtyp" located in our Tashtyp district (1 slide).
For this trip we don't need a boat, we don't even need to get out kindergarten. We will make our journey in our imagination, remember everything we already know, and perhaps learn something new. After all the river is beauty, health, home for river inhabitants and much more.
- Before we go on a trip, let's remember rules:
1. Every day, always, everywhere,
On classes, in Game,
We speak loudly, clearly,
We're not in a hurry.
2. If you want to answer, don’t make noise,
Just raise your hand.
So, let's go on our journey.
D/game: “Find a river "Tashtyp"» (2 slide).
Take a look at these photos. On them you can see different bodies of water. You need to find a picture that shows exactly our river"Tashtyp". Why did you choose this particular picture?
D/game: "Which river?»
Tell me which one it is river in spring? (3 slide) Stormy, fast, cold, deep, long, muddy.
What happens river in summer? (4 slide) Warm, small, affectionate, murmuring, transparent.
What is it like in the fall? (5 slide) Cold, deep, cloudy.
And in the winter season? (6 slide) Frozen, cold, icy.
What action words can be chosen for the river? Swim, swim, fish, dive, splash, frolic….
What living and inanimate natural objects can be found in and near the river? Fish, stones, sand, boat, trees, grass, algae, little ones….
Gymnastics for the eyes “Guess the riddle - find the answer”.
Try to guess the riddles. Just don't say the answer out loud. Look for the picture with the answer.
“Living in the river is not at all boring”,
She will tell you silently.
Even politely "Thank you"
Speaks inaudibly... (fish)
He always goes for a walk
Only backwards.
Any fisherman is familiar with him,
At least he's not a fish, huh. (cancer)
She lives by the water
Sings songs loudly.
Her mouth is a trap for flies,
And her name is. (frog)
Beware, roach, bleak, -
There's a cunning villain in the river!
Hey kids, get out of the way, come on!
I went hunting. (pike)
D/game: "How many syllables are there in a word"
Fish, crayfish, pike, frog, river, fisherman, burbot.
Fizminutka: Let’s close our eyes for a minute and imagine that we are fish and decided to frolic in warm water. The fish swam with the flow, easily and calmly (light and calm music sounds). Suddenly a strong wind began, the fish needed to return home, and they had to make a lot of effort, because the current in the river became stormy and fast (fleeting, fast music sounds).
Guys, please tell me what kind of fish are found in our river?
Why do you think fish do not drown, but swim easily and deftly in the water? Children's answers.
I suggest you come to the table and conduct a small experiment “Why don’t fish drown?”
I suggest lowering a heavy object (stone into water) and say what happened to him.
He sank to the bottom.
Then lower the balloon into the container and find out what happened to it.
He remained on the surface of the water.
The body of the fish is dense, it pulls down. But inside the fish there is "ball"- a swim bladder that is filled with air and pulls upward to the surface (7 slide). Thanks to this combination, the fish swims in the water column.
D/game: "Russell inhabitants»
You see images of different water inhabitants. You need to resettle them in appropriate bodies of water. Name these inhabitants? What can you tell us about the shark; about crab; about the whale; about the octopus. Which body of water was left without inhabitants? What do we need to do? I would like to invite you to choose anyone river dweller, cut it out and put it in the river.
Reflection:
What did we do today?
What was interesting for you?
What was difficult?
How should you behave when you are relaxing by the river?
What is needed to the river didn't get shallow, and so that there will always be fish in it?
What will happen if there is no river?
