Coral fish in the Red Sea.
What kind of fish swim among corals: short, long, thick, transparent?
Bright coral fish singly or in schools swim between the corals, plucking off the polyps they feed on. Their shape and coloring are very diverse. There are red, blue, yellow, green and black fish. They are very shy as they constantly live among immobile corals. Every moving object makes them seek refuge in the reef. Some of the coral fish have powerful jaws that bite off pieces of coral. For example, a parrot fish bites coral twigs, on which algae grow, with teeth tightly fused like a beak. Since this fish has a bright coloring, it has to hide from predators. She does it very skillfully. The parrot fish sinks to the bottom and builds a slime cocoon house around itself. On a coral reef, in clear water pierced sunbeams, butterfly fish swim. These bright, multicolored creatures are very nimble and agile. Above the coral thickets in the water live hedgehog fish and ball fish. If their life is not in danger, they do not attract attention. But as soon as there is a threat in the form of a predator, these fish begin to swallow water and swell in size, frightening predators with their needles and balls. Predatory moray eels love to hide in coral forests. Flexible as snakes fish - a thunderstorm of all small inhabitants of the reef. They swim out of the coral crevice in search of food, such fish can even attack a person. Transparent and colorful jellyfish swim in the depths of the sea. They look harmless but can sting like nettles. On their tentacles there are many cells with poison, which burst when touched. Many of the sea creatures try not to approach the jellyfish, but the fry of some fish hide between the poisonous tentacles from predators. There are many minks in the reef. Interesting neighbors live in some of them - goby fish and shrimp. And they shared the responsibilities equally. The shrimp keeps the dwelling clean and comfortable, and the goby guards the mink and gets food for two. A dog-fish with horns on its head emerges from behind a coral bush. For days on end, the zebra fish freezes among the corals, lying in wait for small fish. In its upper fin on the back, spines with strong poison are hidden. Here, a motley gurnard nearby makes strange sounds, similar to grumbling. Among the algae and corals, a sea needle is hiding, stretching out with its head down, so no one will find it. Seahorses hide in algae, by the way, they can change their color depending on the color of the plant in which they hide.

tangerines- small very colorful fish that live in coral reefs in the western Pacific Ocean. The name "tangerines" comes from their colorful pattern, which is similar to the clothes of the Chinese mandarin. These are bottom fish. They secrete the toxin in the mucus that coats their bodies and is toxic to some predators.
Imperial angels- one of the most beautiful coral fish, which, moreover, change their color during life. The juvenile has a black body with white and blue concentric stripes. In adults, the body is bright purple with about 25 thin diagonal stripes of yellow-orange. The head becomes emerald above and red-brown below with age, with a characteristic bright mask around the eyes. The emperor lives near the coral reefs of the Indo-Pacific region.
lion fish- This fish is one of the most poisonous fish on the ocean floor. Its venomous spikes are used solely for defensive purposes. For humans, its poison is not fatal. They live near coral reefs and rocky crevices of the Indo-Pacific region.
triggerfish- they usually have a very bright color and are inhabitants of coral reefs. They didn't get their name for nothing. The first spine of their dorsal fin is very powerful and can be rigidly fixed in vertical position with a second thorn
Nudibranchs- gastropods, inhabitants of the bottom. They have fantastic coloring and color patterns.
Discus- Sometimes it is also called "King of the Aquarium". Discus is one of the most beautiful tropical fish.
Picasso triggerfish- the Picasso triggerfish lives in warm shallow waters, inside and outside reefs, where there are many cracks in rocks which they explore in search of food. Habitat - Indian-Pacific region. From the south of the Red Sea to South Africa, the Hawaiian Islands, the Tuamotu Islands, the Lord Howe Islands, Japan. East Atlantic: Senegal to South Africa.
moorish idol- one of the most popular aquarium fish. But these fish are extremely difficult to care for. They do not live long in captivity. In nature, this species has a wide distribution in the Indo-Pacific region in tropical and some temperate waters.
Fish - clowns - commonly found in the warm waters of the Pacific, Red Sea, and Indian Ocean. The peculiar name of the fish comes from its cheerful coloring and active behavior. They live in symbiosis with anemones.
parrot fish- so named because of its bird's beak, which it uses to crush and eat small invertebrates that live in corals.
What is a sessile benthos?
The sea floor is home to many animals that are unable to move. They are called sessile benthos. The most famous of them are coral polyps, bryozoans and sponges. Coral polyps and bryozoans have small tentacles with which they catch food and bring it to the mouth. Sponges filter food particles from the water that passes through the many pores in their bodies. Surely you have seen a natural bath sponge? So know that this is the skeleton of a sea sponge! True, now in stores you can find only synthetic analogues.
How do coral reefs form?
Corals are tiny, tentacled marine animals that look like small trees and live in large colonies. They reproduce by budding, which means that old corals are constantly growing new ones. The baby corals stay near the old corals and in this way a large colony develops over time. But not all corals form reefs. Only a few species are capable of this, primarily stony corals. When these corals die, only a hard calcareous skeleton remains. Layering on each other, these skeletons grow upwards. So there is a kind of multi-storey building, similar to a branched tree. Many of these "skyscrapers" of coral skeletons, located next to each other, is called a coral reef.What shapes and colors do coral colonies have?
Most coral colonies are multicolored and play with all the colors of the rainbow. Their "buildings" also have unusual shapes - they look like branches, horns and fans. There are even pillow-shaped coral colonies with brain-like convolutions.Why do coral reefs only appear in shallow water?
Coral reefs are called ridges formed from the calcareous skeletons of coral polyps in tropical seas. The corals that form the reef live only in shallow water. They can only exist at the depths where sunlight, as certain algae that live in coral colonies need light as a source of energy. Corals, on the other hand, cannot live without these algae, so reefs form at a depth of no more than 45 meters - sunlight does not get further.How do corals eat?
Coral polyps feed on animal plankton. They have a mouth opening that is surrounded by tentacles. The tentacles extend, catch plankton from the water flowing past and send it to the mouth opening. By the way, the same hole also serves to remove undigested food residues.What animal species live in coral reefs?
Coral reefs are home to a large number of animals. Among others, sponges, sea anemones, sea cucumbers, starfish, sea turtles, giant rays, as well as predators: sea snakes and barracudas. One third of the world's fish species live in coral reefs!What types of coral reefs exist?
Coral reefs are divided into three groups: fringing (coastal) reef, atoll and barrier reef. Fringing reefs stretch along the coast like a narrow border. Atolls are called coral islands. They arise, as a rule, from the reefs surrounding volcanic islands. A barrier reef is a rampart-shaped coral reef separated from the continent by a sea strait or lagoon.Why are there so many different creatures in coral reefs?
Most marine animal species live in coral reefs. The reason for this lies in the fact that the reef has an abundance of food for its inhabitants. Herbivorous fish, sea urchins, starfish and many molluscs feed on the algae that live in coral reefs. Sponges filter plankton from the water. Sea anemones stun small fish with their scalding tentacles and then eat them. Predatory fish also feed on small fish that are found there. Now you understand how rich the menu of each inhabitant of the coral reef is!How high do coral reefs reach?
Coral reefs grow quite slowly: depending on the species, from one to 100 centimeters per year. However, they can reach enormous sizes. The Great Barrier Reef off the northeast coast of Australia is the largest on our planet. Its area is 347,800 square kilometers. In 1981, this reef was included in the list of important UNESCO World Natural Heritage Sites.Why are coral fish especially colorful?
Coral refers to a variety of fish that live in coral reefs. Most of them have an unusually bright color, and it is needed primarily for camouflage: thanks to it, fish are difficult to distinguish from coral colonies, and enemies cannot see them. In addition, this delightful coloration plays an important role in choosing a partner and in marking its territory.
The reef is the richest part of the sea with fish, since in addition to the fauna, the viability of which is ensured by the direct use of its food reserves, it is visited by large predators that feed on small reef fish.
Lives on coral reefs an incredible variety of fish species of unusually beautiful colors and small sizes that make up the "coral reef fauna" and feed on what can be found on it: coral polyps, small crustaceans, algae, mollusks and other organisms. In addition, the fauna of coral reefs is a desirable prey for large predators: large trevally often swim to the reef in the confidence to find abundant food there, and the now rare reef shark, fearful and practically safe, lives next to the reef itself. reef shoals inhabited by other fish species that use its food resources. An example is moray eels, which hunt small reef fish at night.
The most widespread and numerous are such representatives of the coral reef fauna as pseudanthias, large flocks of which live at a distance of several centimeters from madrepores, cesiums (Caeseonidae family) and common abudefduffs (Pomacentridae family), also gathering in numerous flocks. At a short distance from the reef and often almost on the surface of the water, you can see beautiful spotted eagles (Aetobatus narinari), large sea devils (Manta birostris), feeding mainly on tylosurs (Tylosurus choram), which in turn hunt small fish. Frequent visitors to the reef are the anemone-dwelling amphiprions, dascillas and chromis, belonging to the huge pomacentric family, colorful butterfly fish (family Chaetodontidae), whose constant presence distinguishes Red Sea coral reefs, and angelfish (family Pomacanthidae), for the elegance of their scaly cover considered the most beautiful reef fish. Also typical of reefs parrot fish(of the Scaridae family), which have a hard beak with which they destroy corals in search of coral polyps, on which they feed, thus producing an incredible amount of coral sand (according to calculations, each specimen produces hundreds of kilograms of sand per year).
On the reef platform, at a depth of several centimeters and in close proximity to its edge, many species of surgical fish (family Acanthuridae) live, which include one-horned hornfish with a caudal fin equipped with sharp spikes. Also in close proximity to the edge of the reef, small flocks of black-striped crucian carp (Acanthopagrus bifasciatus) swim, and sometimes you can meet the lone king of the reefs, the largest Red Sea reef fish - Napoleon(Cheilinus undulatus). Its length can exceed two meters, and weight - 200 kilograms. This fish has a very sociable and curious nature and therefore allows snorkelers and divers to approach it.
dangerous fish
Rare Red Sea fish can be a real danger for snorkelers, especially if you follow the rule - do not touch ... But in some cases, you really need to be especially careful!
Contrary to popular belief, most dangerous for snorkelers and scuba divers the Red Sea fish are not sharks at all. A more real danger is posed by blue-finned balistoids during their nesting period, between June and August. Extremely territorial and aggressive, they are ready to attack anyone who swims too close to their nest dug in the sandy bottom. Since these fish have a hard mouth capable of crushing even the hardest madrepores and reach a length of 70 centimeters, they can be a real danger. Compared to them, lionfish have a fearful and peace-loving character, but if touched, their dorsal spines, connected to poison glands, can inject a very dangerous toxin into the wounds. Even more dangerous is the wart, which usually lives on a sandy or algae-covered bottom: its dorsal spines inject poison that is fatal even to humans. Also lives on the sandy bottom stingray stingray, whose tail fin has a poisonous spike that causes painful stings if you accidentally step on this stingray. In conclusion, great care must be taken not to accidentally touch the surgeonfish (family Acanthuridae) living on the reef platform. Their tail fins are equipped with plates, sharp as a scalpel blade.
shells
The so-called "shells", enchanting with their beauty and variety of colors and patterns, are the protective shell of a large group (phylum) of organisms called molluscs.
The type of mollusk includes tens of thousands of species, divided into five large classes. Two of them, bivalves and gastropods, are of undeniable interest to people involved in snorkeling or diving in the Red Sea. Bivalves, as the name indicates, have a shell consisting of two valves connected to each other by a ligament, inside which is the body of the mollusk. They are filter feeders and their gills trap oxygen and microorganisms present in seawater. The most common representative of bivalves is tridacna, which is also the largest representative of this class: its dimensions can exceed one meter and its weight is 300 kg. Another class - gastropods, have a single shell different forms.
Conical and flattened - for marine saucers, spiral - for cones (genus Conus) and Nerite (genus Nenta), which can always be found on the shore. The most beautiful gastropod mollusc of the Red Sea is considered to have already become rare Horn of Triton(Charonia tritonis), which is the most dangerous enemy of the star, the crown of thorns - a favorite delicacy of the mollusk.
Deadly Bite
Shells are not always as harmless as it might seem. A textile cone, quite common on the sandy bottom of the Red Sea, can be deadly if not handled properly. The cone can throw poisonous harpoon tooth, commonly used to catch small prey. The poison they secrete is a serious danger even to humans.
Sea urchins and starfish
Sea urchins and starfish belong to a huge group of echinoderms, numbering more than 6 thousand species. But some of them can be dangerous.
Echinoderms are organisms with very different appearance, but all of them are united by a symmetrical radial skeleton, consisting of calcareous plates (external skeleton) and the presence of an ambulacral system. The most famous of them are sea urchins belonging to the class Echmoidea. In shallow lagoon waters or on a reef platform, you will almost certainly encounter a black diadem. But you need to be very careful, because if you touch or accidentally step on a sea urchin, then its thin spikes, up to 20 cm long, painfully dig into the body. Less common slate sea urchin, so called because its thick spines resemble slates. There are also starfish belonging to the class Asteroidea and characterized by the presence of five or more limbs.
The most beautiful of these is of course the Egyptian Homophia, with its unique bright red coloration, while the most common is the Scolopendrina, which can be found close to the shore at a depth of several centimeters, and the most dangerous is the Crown of Thorns star.
Dolphins and turtles
In the Red Sea, you can often meet dolphins and turtles. These meetings always evoke positive emotions.
In the Red Sea Dozens of species of dolphins live. The most common of these are common bottlenose dolphins (Tursiops truncatus), relatively small long-snouted dolphins (Stenella longtrostris), usually living in flocks of more than 200 individuals, and gray dolphins (Grampus griseus) with their characteristic rounded head and often scarred body. Local guides often refer to the latter as beluga, which is incorrect as it is the name of an arctic species. Turtles endangered are represented by five species. The most common are the hawksbill (Eretmochelys imbitcata), which has a pointed snout and measures less than 90 centimeters, and the green tortoise (Chelonia mydas) with a rounded snout and much larger sizes: it can reach 140 cm in length and its weight can exceed 300 kg. Both species feed on algae, sponges and occasionally alcyonaria and are listed in the IUCN Red List.
What fish live in coral reefs?
The coloring of most fish matches their surroundings. Darkness reigns at great depths, and deep sea fish usually either black or red. Where twilight reigns, fish are most often blue-gray. On the coral reefs of tropical seas, where there is a lot of light and everything is painted in bright colors, fish of the most fantastically colorful and bright colors live.
Let's start with bristletooths, which include butterflyfish and angelfish.
Butterfly fish are not inferior in color and patterns to tropical butterflies. They live in pairs or small groups, hiding from danger in the crevices of coral thickets. These harmless creatures feed on small animals or algae. But there are predators and fighters among them. With protruding spines of the dorsal fins, they can injure their relatives, who are driven away from the area where they constantly feed. No less beautiful are angelfish, especially the imperial angel, decorated with 25 yellow-orange stripes on a dark purple background. Surgeons are brown, brown, orange, green, blue, with bright spots or stripes on the head or body. All surgeons have a sharp powerful movable spike at the base of the tail. They turn this most dangerous weapon against anyone who dares to disturb them.
With their bright color, amphiprions resemble clowns performing in the circus arena, for which they are sometimes called clowns. Amphiprions live among the tentacles of anemones. As a result of this cohabitation, the amphiprion receives protection, and the sea anemone receives an additional source of food - the remains of fish that are eaten by amphiprions. Anemone is an intestinal animal. With numerous tentacles, she catches crustaceans and fish. The stinging cells on her tentacles secrete a poison with which she kills her victims. Only amphiprions are not afraid of anemone poison, as their body is protected by mucus.
Outlandish appearance in lionfish; their large pectoral fins look like wings, and long poisonous spines protrude from their dorsal fins. Lionfish sneak up on gaping fish and ram them with thorns. Some species of lionfish hunt from ambush. Hidden, they play with unusually long spines, and then they can not be distinguished from a bunch of algae.
No less magnificent than other inhabitants of the reefs, triggerfish are painted. Large-spotted triggerfish - black, with bright yellow spots on the sides and silver-blue fins, and coral - fiery red with yellow and blue stripes in front and golden-iridescent fins. These pufferfish seem to consist of only a head and a tail. The dorsal fin of three spines triggerfish can tuck into a groove on its back. One of the spines is so powerful that it resembles a horn, hence the Russian name for the fish. And the second, like a latch, secures the position of the "horn". If you try to extract the triggerfish from its hiding place in the crack of the reef, it will spread its fin so that it will be possible to pull it out only together with a piece of reef. The teeth of triggerfish act like wire cutters. In the outer row of the upper and lower jaws, he has eight powerful teeth each, and on the upper - six more.
Therefore, the triggerfish easily breaks off branches of corals, crushes shells of mollusks, shells sea urchins and crabs. When a triggerfish is pulled out of the water, it grunts.
The local population of the Hawaiian Islands calls their two species "humuhumu-nukunuku-wapaa", imitating the sounds they make. Triggers are harmless creatures, but they can also attack a person if he approaches a flock of their juveniles.
In the most unusual way, pufferfish and hedgehogs, also belonging to the order of pufferfish, protect themselves from annoying predators. Swimming to the surface of the water, the pufferfish quickly draws in air and turns into a motionless prickly ball. When he releases air, a drum sound is heard. At depth, the pufferfish swallows water and sinks to the bottom. Many pufferfish are poisonous. The poison is contained in their skin, peritoneum, liver, caviar and milk.
Properly prepared after cutting by specially trained chefs, Pufferfish is a delicacy that is highly valued in Japan.
This photo shows two pufferfish - bloated and at rest.

Surgeon fish lives in tropical seas.
Like pufferfish, when threatened, hedgehogs swell into a ball with sharp, but not poisonous needles - scales sticking out in all directions. In a calm state, the needles fit snugly to the body.
Among beautiful fish in the reefs there are also those that with "horns" on the head and eyes resemble toy cows. Their scales merge into a shell with holes for the mouth, eyes, fins and tail. These fish are called boxfish. They are poisonous, but this does not always save them from predators.
Buried in the ground, at the bottom lies one of the most dangerous fish - a stone-fish, or a wart. It is very ugly in appearance, the color of its upper part looks like stones, so that it is almost invisible. The wart lives in shallow places near the coast, among coral reefs. Sometimes found on land, where it falls into large ebb tides. Covered with algae, the wart waits for its victims, and if the bather steps on it, it injures him with poisonous spines of the dorsal fin. After two or three hours of torment, death often occurs.
Moray eels look ominous. Their snake-like bodies lack pectoral and ventral fins. Moray eels lurk for hours in crevices and burrows, from where only a very small head with a huge toothy mouth occasionally protrudes. They hunt at night. The meat of some moray eels is poisonous. If there are poisonous glands in the mucous membrane of the palate of the moray eel, then its bite can be fatal. Moray eels, reaching a length of 3 m, are bright blue with black encircling stripes, yellow with orange-brown spots, the Mediterranean has brown and marble spots and stripes on a green-yellow background. The moray eels of the Hawaiian Islands are especially beautiful. The Mediterranean moray has been highly valued by gourmets since ancient times. Her bite is not poisonous, and she herself rarely attacks people, but is very dangerous if caught: the fish wriggles wildly and snaps its huge teeth.

The shallow (1-3 meters) part of the Arabia Beach hotel's coral reef is fenced with buoys,
it is not allowed to swim above it, and even more so to stand on the reefs.
In the picture, shallow water is on the right, and on the left, the bottom topography goes quite sharply deep into the depths.
Yellow parrot fish nibbles corals.
Butterflies and angels are probably the most common fish on coral reefs.
They are small, about 10 centimeters, but varied in shape and color.
This fish, similar to the aquarium angelfish, is called platax.
It is quite large, with a wingspan of 40 centimeters, and at the same time it is flat, like a ribbon.
The fins hang and dangle limply, only the small tail flutters like a fan.
All the days that we rested, this fish lived near the orange rope,
on which a protective buoy is attached.
It was inconvenient to photograph her - either this same rope climbed into the frame,
or the fish turned its tail and slowly, slowly rushed to its heels, into the depths,
not wanting to turn sideways and pose a little.
Schools of fish sailed quite often and very enlivened the landscape.
Thousands of tiny colorful fry glittered in the sun in formless clouds,
and larger fish marked caravan routes and highways with their movement.
Blue fish with yellow tails and pectoral fin tips are blue zebrasomes,
relatives of fish Dory from the cartoon about Nemo.
Parrots come in different colors.
They have characteristic teeth as strong as the beak of a parrot,
with which they gnaw the surface, living, layer from the corals.
The male in the foreground is about 40 centimeters long.
A small fish similar to a lizard camouflages itself at the bottom, at a shallow depth (about a meter).
This is a spotted sand perkia.
One of the most beautiful fish is Acanthurus Sohal Surgeonfish (surgeon fish).
It is said that the orange fins near the tail are very hard and sharp,
like scalpels. Hence the name.
I have already received so many letters containing "fish-surgeon is not like that" that I will answer right here.
The fact is that there are a lot of surgeons (Acanthurus), more than three hundred varieties,
and quite different, so it is possible that you are just familiar with surgeons,
which look different.
I wanted to believe that they were sea pikes - barracudas, a small flock.
But it turned out not.
This is the Red Sea Tylosurus, Tylosurus Choram, that's how.
Good-natured melancholy with a bright disheveled tail.
I can't say anything more about him.
A flock of silvery fish with a dot near the tail - Arabian Pinfish.
There are two dangerous marine life in this picture at once.
Above is a sea urchin. Here it is hard to see, then there will be a better shot with it.
But the blue shell below is a tridacna. This one is still young, small, 10 centimeters.
And sometimes they grow up to a hundred and two hundred kilograms,
and then they are a mortal danger.
If you touch the inner surface, the flaps slam shut,
and it will not be possible to free the arm (or leg). As well as to surface with such a load.
Two wings.
They don’t want to be photographed, they turned away and go to a depth (now - about five meters).
Too bad, the fish are rare and very beautiful. Needles are, of course, poisonous and dangerous.
Crab.
What it's called, I don't know. The picture was taken not under water, but simply on coastal rocks.
The crab sat and basked in the sun, but while I took out the camera,
a German boy ran up and began happily throwing pebbles at the crab.
He ran into the crevice, of course. What do you take from a German boy...
Unfortunately, many behave in this way.
Some people admire the fish even from the shore, rejoice when they swim close to the surface,
while others at the same time necessarily grab the pebbles and begin to throw. And what's wrong with their heads?
Flute fish. Centimeters 70-80 long.
There are quite a few of these fish.
It is curious how the coloring copies the colors of the corals near which the fish swims.
Here is the sea urchin in all its glory. It is definitely not recommended to step on it.
Pain, tumors, convulsions, fever, expensive injections, ruined vacation, sick leave upon arrival home. A horror story not from books ... there are acquaintances who are not lucky.
It can be generally funny - you swim in shallow water, hedgehogs come out in flocks, in heaps -
I don’t know, hunting, or basking in the sun ...
and some aunt carelessly gallops around and shouts:
"I don't know what everyone is thinking and frightening with these hedgehogs! Yes, they are not here, I have never seen them!"
A motley flock of different fish. Shot against the sun, unfortunately.
White dots in the water - it seems to be the spring coral bloom.
This turbidity and suspension made it difficult to photograph.
The Grey-spotted Pufferfish is a small cute fish that looks like an inflatable balloon.
The fins are almost invisible, a kind of airship hangs for itself.
Parrot, 70 centimeters.
It happens that you walk along the streets of Hurghada, and such large parrots are publicly fried in restaurants.
Unpleasant. During the baths, they became like family to us.
They say they love boiled eggs. But it is forbidden to feed the fish - I don’t know why. However, you cannot assign an overseer to every swimmer. But it’s strictly forbidden to break off corals, collect shells - the Egyptians cherish the national treasure, at the airport they shine through until they shake out cosmetic bags (at the same time, by the way, nail scissors are confiscated - they cannot be transported in hand luggage, only in luggage). And for trying to hold a harpoon ...
Devil Scorpion. In the next picture, you can see how she clings to a stone with her tail.
And on the tail is a poisonous thorn, like a scorpion. Again, outrageously dangerous.
Disguised well, rarely seen. We have spoken to enthusiastic divers
they have been diving for ten years, but they have not seen such a thing.
A courtly mannerist dedicated the following poem to the scorpion:
|
Let the measured-gentle foam All in thorns, in ugly growths, A scorpion swims furtively, And the hysterical listens to the cries |
Water skis won't save you Insatiable watery abyss You understand it, you bastard, Where stones bathe in foam |
Well, this is it, selyava.
