Shark perch dolphin pike who is superfluous. Which fish eats which? Predatory lake fish
Fish are a superclass of aquatic vertebrates. They are characterized by gill breathing. They are distributed in both fresh and salt waters; both in mountain streams and in deep ocean trenches. These creatures play a critical role in many aquatic ecosystems and have a huge economic importance for a person. Such is their a brief description of. As you may have guessed, this article will focus on fish, in particular the predatory inhabitants of the underwater kingdom. We will tell you about the most famous and striking predators: you will find out what they eat and what kind of fish eats.
Some lyrics...
As a rule, on a fine sunny day, the water surface reminds us of a large mirror. One has only to look into this “mirror”, as clouds floating through the heavens, as well as trees leaning over a reservoir, will be immediately visible in it. At this moment it may seem that the reservoir is empty and dead, but it is not at all! In fact, life is in full swing under this mirror surface! Sometimes there even flare up serious passions. One of the main actors in this underwater "play" are fish. You won’t immediately understand which fish eats which, but it happens there with enviable regularity!
Who are the fish?
Brief scientific description we have presented these animals to you above. If to speak plain language, then fish is usually called all vertebrates that inhabit fresh and salt water sources. Almost all fish have paired limbs, represented by fins, and their respiratory organs are gills. In terms of zoological classification, fish are common name, which unites 6 independent classes (groups), which differ from each other in one way or another, one of which indicates that the fish belongs to predatory or peaceful individuals. In this article, we are more interested in predators. Let's find out which fish eats which.
perch
This is a typical inhabitant of fresh water bodies of our country. Common perch belongs to the most numerous class of highly organized fish - to ray-finned ones. Its body is laterally compressed, has an oval shape and consists of three sections: head, torso, tail. Perch, like all other fish, breathes with gills, so oxygen is vital to it. And he has it, but not quite the same as ours: fish extract oxygen not from the air, but from the water. To do this, the fish is forced to swallow air through the mouth, driving it through the gill cavity, located under the gill covers.
What does the common perch eat?
Common perch is a predatory lake fish. It is found in rivers, lakes, ponds, reservoirs in Europe and North Asia. Perch was introduced to Africa, New Zealand, Australia. The diet of these fish is made up of others. Initially, the perch fry feed on zooplankton, and as soon as they grow up, they begin to hunt the young of other perch and cyprinids. These fish begin to feed on fry of other relatives, as a rule, in the second year of their life. With age common perch switches to hunting for larger and more mobile fish.
How do perches hunt?
Adults are agile and quite strong predators. They swim very fast, sometimes stopping completely, but then instantly rush forward. These fish have huge mouth located at the anterior end of the head. In the mouth, even with the naked eye, you can see the jaws, studded with numerous teeth, however, small ones. If perches start their hunt, then someone will definitely not be in trouble!
Predatory lake fish can pursue their prey long and hard. The perch rushes after it, opening its huge mouth and making a kind of “champing”. Fishermen say that a frightened victim often jumps out of the water, but this still does not save her: the perch gets what he wants. Sometimes these predators, too carried away by the pursuit of their prey, run aground after it, and sometimes onto the coastal sand ... In general, perches are predators from God: these voracious creatures will not miss a single creature able to fit in their wide mouth.
Common pike
Common pike is a predatory fish that inhabits fresh water North America and all of Eurasia. Usually it can be found in the coastal zone, in water thickets, in slow-flowing or completely stagnant waters. From this point of view, pikes are river predators. But often they are also found in desalinated areas of certain seas. For example, you can meet pike in Riga, Finnish and Baltic Sea, as well as in the Taganrog Bay Sea of Azov. So from this point of view, pikes are predatory fish of the sea.
What does the common pike eat?
Her main diet is based on representatives various kinds fish. For example, they are happy to attack:
- perch;
- ruff;
- minnows;
- scavengers;
- minnows;
- bream;
- goltsov;
- sculpin gobies.
Answering the question about which fish eats what, avid fishermen say that it is the pike that comes to mind that eats roach with pleasure. It is understandable: the fact is that the pike is the unspoken symbol of all river predators in our country, and the roach is her favorite food.
Ichthyologists describe cases when these fish grabbed and dragged mice, rats, little ducklings, waders and even squirrels into the water! All these animals swam across fresh water during their seasonal migrations. Large individuals can generally attack adult ducks, especially during their molt. In spring and at the beginning of the summer season, pikes readily feed on crayfish and frogs. By the way, a fish that is almost twice the size of the predator itself can often become a victim of a pike!
The most dangerous and predatory fish on Earth - white shark
The predatory fish, called the man-eating shark, carcharodon, or great white shark, is the most feared and one of largest fish on our planet. On average, these predators grow up to 4.7 meters in length, however, ichthyologists have recorded individual individuals reaching 7 meters in length and weighing up to 1900 kilograms. Sharks do not have bones, their skeleton consists entirely of cartilage. The skin of many of them is covered with razor-sharp spines. It is curious that the inhabitants of some islands use shark skin as a grinding material.
Where do white sharks live?
Their distribution area is huge! These predators live in open oceans and coastal waters of the island and continental shelves, the temperature of which reaches 13-25 degrees Celsius. But there are also sharks who prefer to swim in tropical waters. The main territory of the accumulation of these monsters is coastal waters Baja California (Mexico), California (USA), New Zealand, Australia, South Africa and mediterranean sea. This scary fish you can meet (but it’s better not to meet!) And off the East coast of the USA, off the coast of the island of Cuba, Argentina, Brazil, etc. She inhabits the Red Sea ( Indian Ocean), Seychelles, the waters of Mauritius, etc.
What does the white shark eat?
White sharks are predatory fish (photo below), devouring everything in their path. “A wolf on land is a shark in the sea,” sailors say. And not in vain! These dangerous predators pursue ships in flocks in anticipation that a person or other living creatures will fall into the water. But, as a rule, this does not happen, so white sharks (and sharks in general) with great pleasure eat everything that ill-mannered people do not throw into trash cans, but straight from ships into the seas and oceans:
- cans;
- flasks;
- empty bottles;
- disposable tableware;
- other rubbish.
If we talk about animal feed, then these fish hunt mainly in the daytime and eat animals such as:
- slopes;
- tuna;
- other sharks;
- dolphins;
- porpoises;
- whales;
- seals;
- seals;
- sea turtles;
- birds.
White sharks can also be scavengers: they will never bypass the carcass of a dead whale. By the way, the hunting tactics of these predators directly depends on this or that prey. For example, near Forces Island they attack Cape seals at high speeds, and off the coast of California they immobilize northern ones, these sea predators grab them right from the surface of the water, dragging them into the depths of the sea.
