Electric eel fish mysterious and dangerous, lives in shallow muddy rivers of the North-Eastern part of the South American continent. To ordinary acne he has no relation, being gymnamoebae fish. Its main feature - the ability to generate electric charges of different power and destination, and to detect electric field.

Habitat

Over the millennia, the evolution of electric eels have adapted to survive in extremely adverse conditions overgrown and silted reservoirs. His usual habitat is stagnant, warm and turbid water with large oxygen deficiency.

Acne is Breathing atmospheric air, so every quarter of an hour or more he rises to the water surface for grasping portions of air. If you deprive him of this possibility, he suffocates. But without any harm to acne can live without water for several hours, if his body and mouth are moistened.

Description

Electric eel elongated body, slightly compressed laterally and behind, rounded in front. The color of the adults is greenish-brown. The throat and lower part of the flattened heads of bright orange color. A characteristic feature is the absence of scales, the skin is covered with slime.

How an eel generates electricity

The fish Grows on the average up to 1.5 m in length and weighs up to 20 kg, but there are three-meter instances. The absence of a ventral and a dorsal fin increases the similarity eel with a snake. It moves by undulating in large anal fin. Equally can easily move up and down, back and forth. The pectoral fins are of small size when the motion function as stabilizers.

Leads a solitary lifestyle. Most of the time at the bottom of the river, motionless among the thickets of seaweed. Awake and eels hunt at night. They feed mainly on small fish, amphibians, crustaceans, and if you're lucky, birds and small animals. The victim is swallowed whole.

Unique feature

In fact, the ability to create electricity is not some sort of amazing feature. Any living organism can do it to some extent. For example, our brain controls muscles with electrical signals. Acne produces electricity exactly the same as the muscles and nerves in our body. Electrolytes the cells accumulate the energy derived from food. Synchronous generating their action potentials leads to the formation of short electrical discharges. In the result of summation of thousands of tiny charges accumulated in each cell creates a voltage up to 650 V.

The Eel emits electric charges of different power and purpose: pulse protection, fishing, peace and the search.

In repose it lies on the bottom and does not generate any electrical signals. Hungry slowly begins to float, emitting pulses with a voltage up to 50 V with an approximate duration of 2 MS.

 fins eel

Finding prey, dramatically increases their frequency and amplitude: the intensity increases to 300-600 V, duration of 0.6-2 MS. The series of pulses consists of 50-400 discharges. Send electric shocks to paralyse the victim. To stun small fish, which the eel in the ground and feeds it uses high frequency pulses. Pause between each digit uses to restore energy.

When obezdwijivanie the victim sinks to the bottom, the eel swims quietly to her and just swallow you whole, and then resting for a while, digesting food.

Defending against enemies, the eel emits series of rare high-voltage pulses in an amount of from 2 to 7, and 3 small amplitude search.

Electrolyze

The Electric organs of eels are not only for hunting and protection. Weak discharges with a capacity of up to 10 To they use to electrolocation. The eyesight of these fish are weak, but old age is deteriorating. Information about the world they receive from electrical sensors located throughout the body. In the photo, the electric eel its receptors are clearly visible.

Eel lurking at the bottom

Around floating eel pulsing electric field. As soon as within the scope of the field is an object, such as fish, plant, stone, the shape of the field.

Catching the special receptors of the distortion created by the electric field that it finds in the murky waters of the path and hiding the booty. This hypersensitivity provides the electric eel the advantage over other types of fish and animals that rely on sight, smell, hearing, touch, taste.

Electric organs of eels

what is acne

The Generation of discharges of the various power made bodies of different types, occupying nearly 4/5 length of the fish. In the front part of his body is the positive pole of the "battery" in the tail area are negative. The authorities of Maine and hunter produce pulses of high voltage. Discharges for the implementation of the communication and navigation functions are generated on the Saks,located in the tail. The distance at which individuals can communicate with each other, is about 7 meters. To do this, they emit a series of discharges of a particular type.

The Highest category of electric eels recorded from contained in the aquariums of fish reached 650 V. the fish meter length it is no more than 350 V. This power is enough to light five light bulbs.

How eels are protected from electrocution

What is acne

Generated during hunting, the electric eel voltage reaches 300-600 V. It's lethal for small inhabitants like crabs, fish and frogs. And larger animals such as caimans, tapirs and anacondas adults, prefer to stay away from dangerous places. Why electric eels do not affect the current itself?

The Vital organs of fish (brain and heart) are located close to the head and is protected by fatty tissue that performs the function of the insulator. The same insulating properties it is skin. Observed that the skin damage increases the vulnerability of fish to electric shocks.

Another interesting fact. During mating eels generate a very powerful level, but the damage to the partner they do not cause. Discharge of such power, produced in normal conditions and not during mating, can kill another individual. This suggests that eels have the ability to enable and disable system protection from electric shock.

Reproduction

Eel in captivity

Eels spawn with the onset of the dry season. Males and females find each other, sending water pulses. The male builds from saliva the well hidden nest, where the female lays up to 1700 eggs. Both parents care for the offspring.

Skin fry light Buffy tinge, sometimes with marble stains. The first hatched fry start to eat the remaining eggs. They feed on small invertebrates.

The Electric organs at the fry begin to develop after birth, when their body length reaches 4 cm Small larvae are able to generate a current of a few tens of millivolts. If you take into the hands of Malcolm, who is only a few days old, you can feel the tingling from the electrical discharges.

Growing up to 10-12 cm in length, the young fish start to lead an independent lifestyle.

The captive state

electric eel

Electric eels a good feel in captivity. Life expectancy of males is 10-15 years, females up to 22. How they live in natural environment - is not known.

The Aquarium for keeping these fish must be at least 3 m length and 1.5-2 m deep. The water is often not recommended to change. This leads to the appearance of ulcers on the fish body and their death. The mucus covering the skin of acne, includes antibiotics, anti-ulcers, and frequent change of water, apparently reduces its concentration.

Against the representatives of the kind acne, lack of libido, aggression, so you can keep in the aquarium can only be one individual. Water temperature is maintained at 25 degrees or higher, rigidity - 11-13 degrees, acidity - pH of 7-8.

Dangerous acne for

What an electric eel is particularly dangerous for people? It should be noted that for the person meeting them is not fatal, but can lead to loss of consciousness. The electric discharge of the eel leads to a reduction in the numbness and painful muscles. Unpleasant feeling can last for several hours. Larger individuals have a higher amperage, and the consequences of the defeat of the discharge will be dire.

Length of the electric eel

This is a predatory fish that attacks without warning, even on a larger opponent. If an object is within the radius of its electric field, it does not float away and not hiding, preferring to attack first. Therefore, to approach the foot eel closer than 3 meters, in any case impossible.

Although fish is a delicacy, catching her is deadly. The locals have devised a novel way of catching electric eels. They use cows who are well tolerate the shock of electrical discharges. Anglers are driving a herd of animals in the water and waiting for when the cows stop frightened mumble and rush. After that they kicked out on the land, and begin networking to catch already harmless eels. Electric eels cannot generate current, and the discharge gradually becomes weaker and does expire.
