Skates have a lot of interesting features, which, in fact, differ from other representatives of the fauna living in the water.

Scientists came to the conclusion that even in the past, the ancestors of sharks and rays were not much different in body structure. But still millions of years have made these animals different from each other.

Scat: what kind of

Skates are related to the order of the nodulescartilaginous fish, which charge five orders and fifteen families. The modern fish of the stingray (it can be clearly seen in the photo of the animal) is characterized by an incredibly flat body and a head that has grown together with the pectoral fins, which gives this creature an interesting and possibly fantastic appearance. The color of this animal depends mainly on its habitat:

  • sea ​​water;
  • fresh water.

The types of skates are very different both in size,and on behavior. The size of this species of animal varies from a couple of centimeters to several meters. The wingspan can reach more than two meters (for example, ramps from the family of eagles). Electric skates have their own important feature in the form of weapons. They paralyze the victim by electric discharges, which produce all kinds of rays, but only 220 volts in volume. This category is enough to not only paralyze some parts of the human body, but also lead to death.


Most types of skates are benthic and eat shellfish, crayfish. Pelagic species use plankton and small fish. Let's figure out which groups the scientists are singling out:

  • electric;
  • sawlogs;
  • ramp-shaped;
  • caudal in shape.

Different types of stingrays can be found in the mostdifferent places of our globe. They are found in Antarctica and in the Arctic Ocean. If you want to see the flying stingray with your own eyes, then go to the coast of Australia, there are more than enough of them. The most diverse types of skates, photos of which are presented in this article, fully disclose the entire history of their existence and modern life.

Unique respiratory system

Carpets-planes of the underwater world are the fish of the stingray. The species of these animals are unique in nature, because they have a different respiratory system than other fishes that breathe with gills. The air passes into the body of the rays through special sprays located on the back. These devices are protected by a special valve. If it happens that a foreign object gets into them, the sting moves away from it by the method of releasing a stream of water from the spray.

On the motion of the rays are like butterflies. For movement, they do not use the tail, as do other fish. They move by means of fins.

Distinctive features

All the slopes differ from each other, first,dimensions. In nature, fish are known for only a couple of centimeters, and skates, whose size reaches seven meters. In addition, the behavior of each species is completely different. Some of them do not mind jumping over the surface of the water, while others prefer to burrow into the sand and quietly rest.

Fish stingray - a predatory animal, the main food are the following marine life:

As for reproduction, some of the species are viviparous, while others lay eggs in special natural capsules.

Sea rays: species

  1. Orlyak - from the family of large fish, leadpelagic way of life. These large creatures freely swim in the high seas and in tropical regions. Orlyak rays are moved with the help of undulating swings of their wings - fins. Manty and morobes filter water from plankton.

  3. Guitar reminds the kind of sharks, but they havegills, which relates them to the slopes. They use the tail precisely for movement, than the sharks resemble. They feed on small fish and shellfish. The victims are thrown from above, pressed down to the ground and then eaten.
  4. Gneusovye - a family of electric rays,there are about 40 species. They are inactive, swim very slowly, as a rule, lie on the bottom, buried in the sand. If the prey swam close, one electric shock is enough to stun it, and then to eat. Electric discharges they use for defense.
  5. Narcine - slow bottom fish, produce no more than 37 volts. They live in temperate latitudes, like closed sandy bays near coral reefs, river mouths.
  6. The pilasters include seven species of fish-saws. In general, they resemble sharks, they live in tropical places. They feed on schooling fish. When burst into a flock of sardines, they beat the fish with a saw, like a sword, and after that pick up the prey from the bottom. For a person, there is no danger.
