Complex with aquariums where marine animals live

At the moment there are more questions than answers

complex, aquariums, marine, animals, live

Animals (in the form of lines) are small.

Now we can say with confidence that there is life under the glaciers of Antarctica. However, there are no exact answers to the main questions, only theories and assumptions.

Our discovery poses more questions than it answers. For example, how did they [the animals] get there? What do they eat? How long have they been there? How many more of these boulders covered with life? Is it the same species that lives outside the ice shelf, or is it completely new? What happens to these colonies if the glacier collapses.

For statements and confident hypotheses, scientists need to collect samples from the bottom and stone, which has not yet been done.

12 unknown animals found under ice in Antarctica. Scientists lowered the GoPro there and were surprised

There are more than 1.6 million animal species around the world. It seemed that we already know about all creatures on our planet, but this is not so.

British Antarctic Survey scientists find unknown animals in Antarctic glaciers.

The discovery became one of the most interesting in 2021, and not only in the scientific community. This is due to the fact that the discovered animals lived where it was previously impossible to imagine the existence of any living organisms.

Next, you will find out who and how discovered these animals, what species they belong to, what is known about them and how old they are.

22 unknown animals found at a depth of 1.2 km

Animals are mostly found on the sides of the boulder. In the picture above, life is visible in places A-E, unlike point F, located at the top of the stone.

In total, three categories of animals living on the boulder can be distinguished:

▪️ 1 stem sponge
▪️ 15 other types of sponges
▪️ 22 unknown organisms (possibly sponges, ascidians, hydroids, shells, creeping or polychaetes)

At the moment, scientists can say with confidence that these animals live in complete darkness. There is nothing surprising. Many marine inhabitants live in similar conditions.

Presumably, animals feed by chemosynthesis of bacteria around. However, for this, trace elements must pass under water in the area of ​​the stone.

This is possible, given the peculiarities of currents around Antarctica. In addition, in the sediments surrounding the stone, the researchers also noticed ripples, which are usually formed by currents, which supports the theory that food comes here from afar.

What is known about the Filchner-Ronne ice shelf

The Filchner-Ronne Ice Shelf is the second largest ice shelf in Antarctica. Its area is about 422 thousand km² (slightly smaller than Sweden).

In 1912 the eastern part of the glacier was discovered by the German explorer Wilhelm Filchner. In 1947, the western part of the glacier was discovered by the American polar explorer Finn Ronne.

Filchner-Ronne Ice Shelf (highlighted in red)

Sometimes huge icebergs separate from the glacier. So, in October 1998, an iceberg A-38 was formed, which was larger in size than Moscow and St. Petersburg combined.

It later split into several parts that floated in the ocean until 2005.

An iceberg that broke away from a glacier at the end of the 20th century.

In their article, Smith and his colleagues point out that we know almost nothing about ice shelves. This makes it difficult to predict their behavior.

The purpose of this expedition was precisely to study the glacier. We can already say that its result met all expectations.

What else is interesting to read about nature:

This animal may be several thousand years old.

It is unclear how the motionless animals got to this place. There is a theory that their parents lived on another rock or rock hundreds of kilometers away. where the ice shelf ends and more typical marine ecosystems begin. Perhaps their parents laid eggs, which then moved downstream and at some point stopped on this stone.

Also, now it is impossible to say exactly how old these animals are. Antarctic sponges are known to live for thousands of years. therefore, it is possible that this is a truly ancient ecosystem.

There is also a theory that life on this stone appeared a very long time ago, and underwater currents brought new inhabitants for millennia.

It is possible that there is more than one similar stone under the glacier.

The animals were discovered by accident under a thick layer of ice. Helped GoPro

Geologist James Smith of the British Antarctic Survey and other scientists studied the Filchner-Ronne Ice Shelf in West Antarctica. They needed seabed sediments to learn its history.

Scientists wanted to collect samples of bottom sediments, so they made five drilling sites in different parts of the glacier (FSW1, FSW2, FSE1, FSE2, FNE2).

Glacier wells diagram.

Smith and his colleagues dug a small well and then melted 20 tons of snow to produce 20,000 liters of hot water. They pumped this water through a pipe lowered into a well and thus a small but deep tunnel was created. The whole process took 20 hours.

After that, scientists lowered a sampler into the well with an attached GoPro HERO4 camera, which recorded video in Full HD resolution.

The main observation site was the FSW2 drill site. Its total depth is 1344 meters, of which 872 meters is a glacier, and 472 meters is water at the bottom.

Despite numerous attempts to obtain material from the bottom, each time the sampler came across a large, semi-circular dark boulder. It was under it that a diverse benthic fauna was discovered.

The very stone on which unknown creatures live.

Previously, scientists believed that low temperatures in Antarctica, lack of light and food did not allow living organisms to live in such places. This discovery confirms the opposite.

The area beneath these ice shelves is probably one of the least known habitats on Earth. We didn’t think that animals could be found there.

The stone is located at a depth of 1233 meters and measures approximately 96x69x75 cm.

As it turned out later, there was only this stone at the bottom. And if Smith had chosen a different location for drilling, most likely we would never have known about the existence of these organisms.

Appearance and features

A sea lion with a shiny skin is called “sea lion” because of the light mane of coarse hair found on the neck and chest of the male, resembling a lion’s mane. It is sometimes mistaken for a seal, but it is easy to tell the difference. Unlike seals, a sea lion’s outer auricles cover their ears to protect them from water. Steller sea lions also have a bony structure that allows them to walk on all their fins while supporting their full weight.

Interesting fact: As the world’s largest sea lion, an adult sea lion can reach a length of two to three meters. Females weigh between 200 and 300 kilograms, while males have been found to weigh up to 800 kilograms. One massive sea lion weighed almost one ton.

The average sea lion puppy weighs about 20 kilograms at birth. At birth, Steller sea lion puppies have thick, rough, almost black fur with a frosty appearance, because the ends of the hair are colorless. The color lightens after the first molt at the end of summer. Most adult females are colored back. Almost all males remain darker on the front of the neck and chest, some are even reddish in color. Adult males have broad foreheads and muscular necks.

Interesting fact: In the water, the sea lion swims with breaststroke and can reach a maximum speed of about 27 km / h.

The sound of the sea lion is a chorus of low-frequency “roar” of the elderly, mixed with the “lamb” vocalization of young puppies. California sea lions are often heard among sea lions in southeastern Alaska, and their barking sounds are a telltale clue for these smaller, darker sea lions.

Natural enemies of sea lions

For many years, human activities such as hunting and killing have posed the greatest threat to sea lions. Fortunately, these are also the most preventable risks. This large creature is also susceptible to accidental entanglement in fishing gear and may be suffocated by debris around their necks. An entangled sea lion can potentially drown before it can escape or free itself.

Pollution, oil spills and environmental pollution such as heavy metals threaten sea lion habitats. This preventable harm can lead to the displacement of residents from their vital habitats and, ultimately, to a decrease in their numbers.

The sea lion also faces natural threats, such as a decrease in the amount of food available. In addition, killer whales hunt them. As with all animals, the disease poses a potential risk to the sea lion population.

Scientists are currently investigating why sea lion populations are declining. Possible reasons for this include an increase in parasite numbers, morbidity, predation by killer whales, food quality and distribution, environmental factors and nutritional deficiencies caused by natural changes in the abundance of major prey species or competition with other species or humans for food.

One way to differentiate between the two main groups of seals is through the presence of the pinna, a small fluffy earmold (outer ear) found in sea lions and not found in true seals. Real seals are called “seals without ears” because their ears are hard to see, and sea lions are called “eared seals”. The name “otariid” comes from the Greek “otarion” meaning “small ear”, referring to the small but visible outer ears (auricles).

In addition to having an auricle, there are other obvious differences between sea lions and true seals. Steller sea lions have hind fins that can be flipped under the body, helping them move along the ground, while the hind fins of real seals cannot be turned forward under the body, which leads to their slow and awkward movement on the ground.

Sea lions also swim using their long front flippers to navigate the water, while real seals swim using their rear flippers and lower body in a side-to-side motion. There are also behavioral differences, including in the breeding system.

Population and status of the species

The two sea lion populations represent different genetic, morphological, ecological and population trends. Population trends in eastern and western populations differ for complex reasons. In simple terms, the difference is likely a result of the different types and magnitudes of threats that the species faces throughout its range.

The western population includes all sea lions originating from the rookeries west of Sakling Point. The sea lion population declined from about 220,000 to 265,000 in the late 1970s to less than 50,000 in 2000. While the population of the west has generally grown slowly since about 2003, it is still rapidly declining over large areas of its range.

The eastern population includes sea lions originating from rookeries east of Sakling Point. Between 1989 and 2015, their numbers in the east increased at a rate of 4.76% per year, based on an analysis of the number of puppies in California, Oregon, British Columbia and southeastern Alaska. than 80% of the sea lion population disappeared from Russia and most Alaskan waters (the Gulf of Alaska and the Bering Sea) between 1980 and 2000, leaving fewer than 55,000 individuals. Sea lions are in the Red Book as those who are in danger of extinction in the near future.

Threats to sea lions include
:

  • blows from a boat or ship;
  • pollution;
  • degradation of the habitat;
  • illegal hunting or shooting;
  • offshore oil and gas exploration;
  • interaction (direct and indirect) with fisheries.

The direct impact on the fishery is largely due to the gear (drift and gillnets, longlines, trawls, etc.) that can entangle, snag, injure or kill sea lions. They were seen entangled in fishing equipment, which is considered “serious injury.” Indirect impacts of fishing include the need to compete for food resources and possible modifications to critical habitats from fishing activities.

  • hunting for their meat, skins, oil and various other products (in the 1800s);
  • bounty homicide (early 1900s);
  • killing in order to limit their predation on fish in aquaculture establishments (fish farms). But the deliberate killing of sea lions was not permitted as they were protected under the Marine Mammal Protection Act.

Sea lion

The sea lion is the largest member of the Otariidae family, the “eared seals”, which includes all sea lions and fur seals. It is the only member of the genus Eumetopias. Eared seals differ from molluscs, “true seals”, in the presence of external ear valves, long forearms resembling flippers used for propelling, and rotating hind flippers that allow quadrupeds to move on land.

Social structure and reproduction

Sea lions are colonial breeders. They have a polygynous mating system in which only a small proportion of sexually mature males sire most of the puppies at certain times of the year.

The mating season for the sea lion is from late May to early July. At this time, the female returns to her home rookery. an isolated rock, where adults gather for mating and childbirth. to give birth to one puppy. During the mating season, sea lions gather in dense colonies for safety, away from land-based predators. The sounds of adults and the bleating of newborn puppies create a loud shielding noise. This collective and constant noise scares away possible predators.

A female sea lion takes care of her puppy for one to three years. The mother stays on land with her puppies for one day and then goes to sea to collect food the next day. She follows this pattern to feed her puppies while continuing to maintain her own diet.

A newborn sea lion is a dexterous little creature. He can crawl from birth and learns to swim at about four weeks of age. Although difficult to assess, it seems that the mortality rate for puppies is quite high and may be the result of crowding out of older animals or when they are forced to leave the rookery, they are unable to swim and drown.

Puppies develop immunity to most diseases while they are breastfed. As they grow older and weaned, puppies can become sick from internal parasites (such as roundworms and tapeworms) that affect growth and longevity. The female sea lion is acutely aware of her puppy’s needs, never leaving him for more than a day at a time, during the critical first month of his life.

What does the sea lion eat?

Sea lions are carnivores with sharp teeth and strong jaws that eat their prey. They catch their own fish and eat whatever is most readily available in their area. In British Columbia, the sea lion eats mainly school fish such as herring, hake, salmon and sardines. Sometimes they dive deeper to catch sea bass, flounder, squid and octopus.

Interesting fact: Sea lions are excellent swimmers who sometimes dive deeper than 350 meters in search of food and usually stay submerged for no more than five minutes at a time.

Adult sea lions feed on a wide variety of fish, including Pacific herring, gerbil, Atka mackerel, pollock, salmon, cod and rock fish. They also eat octopus and some squid. On average, an adult sea lion needs about 6% of its body weight per day. Young sea lions require twice as much food.

Sea lions also kill seals and other animals. On the Pribilof Islands, young male sea lions were seen killing and eating Northern fur seal puppies, while elsewhere they occasionally ate ringed seals. Due to their diet, sea lions can influence populations of fish, bivalve molluscs, gastropods and cephalopods.

Reef aquarium. your SEA in miniature

When I was four years old, my parents started an aquarium. Unpretentious, freshwater. even to a little one, it seemed tiny to me. And since none of us had any experience in content, it did not work out right away with it. Frogs constantly jumped out, and it was necessary to catch them before the dog did it, the snails artistically covered all accessible surfaces with clutches of eggs, and the fish, which I designated as my favorite, was eaten first. In general, soon our aquarium was given into good hands, and this was the best thing that happened to him. And even then I realized that the aquarium is difficult and requires a lot of responsibility.

The life support of a personal sea. a huge and colorful aquarium where, in addition to fish, coral reefs live. requires a complex lighting system, filters, pumps, pumps, cooling systems. Recreating the natural environment is not easy. Not easy, but possible! In the editorial office, we decided to talk to Alexander Loginov, a man who creates marine aquariums, to find out more about their content. Alexander spoke about coral farms, fish bullying, prototypes of the heroes Nemo and Dory, and also dispelled the myth of “fish memory”.

I personally like marine aquariums more than freshwater ones. Here the underwater world is richer. there are many types of fish, corals of stunning colors and shapes. The reef itself is one of the most diverse biotopes in the world in terms of the number of species

The fish living here are also ten years old, they have not changed here since 2009. There were others who have already died, but these do not show that they were going to retire. Many species live for a long time. from five years exactly, and some live up to twenty-five.

In the late nineties and early 2000s, marine aquaristics began to actively develop, both technologies and methods were improved. At that time it was still in its infancy, there were no special offers on the market. I set up a marine aquarium at home, and it was a hobby, but gradually it grew into my life’s work.

Our company is a leader in the marine aquarium market in Ukraine. I can say this without undue modesty. We provide a full range of services: design project, installation of the aquarium itself, the necessary equipment and electronics, we populate fish and corals, support autonomous work and advise after the aquarium is launched. Up to the fact that we manufacture equipment. Also, our specialists help to ensure fast growth and bright design in the aquarium.

We have our own farm. Corals reproduce by fission, so the reef needs to be thinned constantly. Some corals cover themselves, others grow more intensively and cover the rest.

The largest and probably the most ambitious was the aquarium that was on the barge.

If this is not followed, then some species will begin to dominate and eventually capture the entire aquarium. What is thinned out can be planted in the same aquarium, it can be on the farm, it can be glued to the pebbles, and these will already be fragments that can be transferred. Previously, both fish and corals were imported. But now life has turned in such a way that many countries, which previously allowed their export officially, have introduced a complete ban on this. Even though in Indonesia corals for import were grown on farms, there was a complete ban on the export of any coral. over, the species grown in the sea could not always acclimatize after transportation. Therefore, modern aquarism has moved towards the cultivation of the brightest and most beautiful corals in artificial conditions. Many rare species that have an unusual color and shape were first found in nature, and then underwent selection. In fact, it’s hard to find corals of this color on a reef.

The barge made voyages along the Dnieper, but often stood at the seaport for a long time. We did all the technical part and were occupied with the settlement of this aquarium. Large, about 30 tons. 5 m long, 3 m wide and 2 m deep.

As a rule, people have their own idea of ​​\ u200b \ u200bthe size of the aquarium and how it should be.

To begin with, to understand whether you like it or not, a 50-100 l aquarium is enough.

Especially for designers. they draw bulbs from floor to ceiling with a width of half a meter. There were often such projects with a tall, narrow aquarium. At the design stage of all structures, I immediately say that this is unattainable.

Frequent mistakes in maintenance are incorrect selection of equipment and violation of the order of settling the aquarium, when fish and corals are launched prematurely or incompatible species are allowed on the same territory. For everyone to feel good, the inhabitants of the aquarium must be in balance. The larger the fish, the more difficult it is to keep them together with the corals. The latter need certain water parameters, otherwise they begin to die over time. These parameters are strongly influenced by the waste products of fish. Some part will be assimilated by corals and invertebrates in the aquarium, they need it, otherwise they feel bad. But so that this waste does not accumulate, they must be removed with special equipment. Then both fish and corals are good.

The most important condition for the fish not to get sick is not treatment, but a normal and comfortable aquarium environment for it. The environment should not be hostile, when, for example, some fish are not allowed to eat properly, they beat it. If this is not the case, then, as a rule, the fish’s immunity is quite enough so as not to get sick. Treatment in a reef aquarium is very difficult and almost unrealistic, because any medication destroys biology. If a fish is sick, it still needs to be caught. This is not always possible: there are many decorations, stones, overgrown reefs in the aquarium. Need a bait trap; but if the fish is sick and does not eat, then it will not enter the trap either. Therefore, it is better not to allow a situation when the fish start to get sick. And it is better to add to the aquarium than those that have passed quarantine and adaptation.

Most of the fish that come here need time to acclimatize. You need to replenish your strength, eat right, get used to artificial food, which looks different in nature. The fish need to understand that now the food looks like this, they pour it here. And when she gets used to it, replenishes her strength, eats up. then she can be added to the aquarium.

You also need to take into account such a moment as the order of the addition to the aquarium. it is empty or there are already fish of a similar type there. Fish, as a rule, show aggression towards related and simply similar in color species.

Children are interested when they watch a cartoon about Nemo. Almost all the fish that are presented there can live in the aquarium.

READ  DIY metal aquarium stand

For example, fish-surgeons. inside this type of aggression towards each other, so if I put new surgeons in my aquarium, then almost all the old ones will beat them, they will not let them near the food. They behave this way because they see newcomers as competitors and use all available methods to drive them out. But there is nowhere to expel, except to jump out. Therefore, they beat them, do not give them food, drive them underground.

Those fish that settled here almost at the same time. they, as a rule, do not have aggression. Then, of course, circumstances can change: someone can feel like a master and start to drive others away. But that rarely happens.

In the houses that we serve, very often the fish have names, They are already like family members. And my three-year-old daughter starts every morning by leading me to feed the inhabitants of our house reef. such is the family ritual.

Fish that live in the house for a long time, six months or more, very clearly understand what is happening in the apartment. They see the owner, know where he will come, where the can of food is, at what time they will be fed. They remember everything like that, because it’s a matter of survival. On the reef there is a high density of all life forms, they have competition in obtaining food, there are many predators. Therefore, in marine fish, intelligence, as a rule, is higher than in freshwater ones. Pisces distinguish each other. And people are distinguished. they swim up, and you can feed them from your hands, almost iron them! Just a matter of habit.

Fish don’t show how much they love someone. This fish must be loved. And aquariums must be loved.

P.S. When the meeting ended, a black cat came out to us

But Kuzma only yawned, lay down in a spectacular pose and stuck out his paw beautifully. The fish chief has no time to distribute valuable comments, he is busy with his direct duties. contemplating the magical underwater world.

This is a corner in which all the colors of the rainbow, bright light, always movement. And any aquarium, even if it is not super beautiful, attracts a person’s eye. So much so that time stands still

The best aquariums in Russia

The Oceanarium is a complex of pools and aquariums of various types and sizes, in which various species of marine fish, invertebrates, mammals and reptiles live. Most often, the design of aquariums involves the presence of a transparent wall through which you can observe their inhabitants. In large aquariums, they usually completely reproduce the picture of the seabed, and animals live in their natural environment.

In addition to their entertainment role, aquariums are of great importance in the scientific education of people about the life of marine organisms. They often host exhibitions and presentations of new inhabitants. If desired, visitors can get competent advice about any representative of the sea and ocean from the staff of the institution. than 100 large aquariums have been built in the world.

The review presents the largest aquariums in Russia.

Center for Oceanography and Marine Biology, located in Moscow on the territory of VDNKh. One of the largest aquariums in Europe. The complex was opened in the summer of 2015. The total volume of the aquariums and pools installed in the center is 25 million liters of water. They contain over 12,000 marine animals, fish and plants. than 80 tons of sea salt is used monthly to maintain the salinity of the water.

The territory of the aquarium is divided into 3 parts: aquariums, areas for water shows and a Swimming Center with Dolphins, which consists of 7 pools. The exhibition with the aquarium stretches for 600 m and consists of 80 aquariums, in which over 600 species of exotic fish live. In addition to fish, you can see walruses, seals, sea lions, sharks, etc.
