Electric eel – wikipedia z gas tecate


The electric eel has an elongated, cylindrical body, typically growing to about 2 m (6 ft 7 in) in length, and 20 kg (44 lb) in weight, making them the largest species of the Gymnotiformes. [2] Their coloration is dark gray-brown on the back and yellow or orange on the belly. Mature females have a darker color on the abdomen. They wikipedia electricity consumption have no scales. The mouth is square, and positioned at the end of the snout. The anal fin extends the length of the body to the tip of the tail.

As in other ostariophysan fishes, the swim bladder has two chambers. The anterior chamber is connected to the inner ear by a series of small bones derived from neck vertebrae called the 10 gases and their uses Weberian apparatus, which greatly enhances its hearing capability. The posterior chamber extends along the whole length of the body and electricity prices per kwh 2013 maintains the fish’s buoyancy. E. electricus has a well-developed sense of hearing. This fish has a vascularized respiratory system with gas exchange occurring through epithelial tissue in its buccal cavity. [3] As obligate air-breathers, electric eels must rise to the surface every ten minutes or so to inhale before returning to the bottom. Nearly eighty percent of the v gashi kenga e zagrebit oxygen used by the fish is obtained in this way. [4]

The electric eel has three pairs of abdominal organs that produce electricity: the main organ, the Hunter’s organ, and the Sach’s organ. These organs make up four fifths of its body, and give the electric eel the ability to generate two types of electric organ discharges: low voltage and high voltage. These organs are made of electrocytes, lined o goshi judo up so a current of ions can flow through them and stacked so each one adds to a potential difference. [5]

When the eel finds its prey, the brain sends a signal through the nervous system to the electrocytes. [5] This opens the gas 2 chainz ion channels, allowing sodium to flow through, reversing the polarity momentarily. By causing a sudden difference in electric potential, it generates an electric current in a manner similar to a battery, in which stacked plates each produce an electric potential difference. [5]

In the electric eel, some 5,000 to 6,000 stacked electroplaques can make a shock up to 860 volts and 1 ampere of current (860 watts) for two milliseconds (ms). [ citation needed] Such a shock is extremely unlikely electricity production to be deadly for an adult human, due to the very short duration of the discharge. Atrial fibrillation requires that roughly 700 mA be delivered across the heart muscle for 30 ms or more, far longer than the eel can produce. [ citation needed] Still, this level of current is reportedly enough to produce a brief and painful numbing shock likened to a stun gun discharge, which due to the voltage can be felt for some distance from the fish; this is a common risk for aquarium caretakers and biologists attempting to handle or examine electric eels. [6]

The Sach’s organ is associated gas or electricity for heating with electrolocation. [7] Inside the organ are many muscle-like cells gas laws worksheet with answers, called electrocytes. Each cell can only produce 0.15 V, though the organ can transmit a signal of nearly 10 V overall in amplitude at around 25 Hz in frequency. These signals are emitted by the main organ; the Hunter’s organ can emit signals at rates of several hundred hertz. [7]

The electric eel is unique among the Gymnotiformes in having large electric organs that can produce potentially lethal discharges that allow them to stun prey. [8] Larger voltages have been reported, but the typical output is sufficient to stun or deter virtually any animal. Juveniles produce smaller voltages (about 100 V). They can vary the intensity of the electric discharge, using lower discharges for hunting and gas efficient cars under 5000 higher intensities for stunning prey or defending themselves. They can also concentrate the discharge by curling up and making contact at two points along its body. [9] When agitated, they can produce these intermittent electric shocks over at least an hour without tiring.

Michael Faraday extensively tested the electrical properties of an electric eel, imported from Suriname. For a span of four static electricity bill nye full episode months, Faraday carefully and humanely measured the electrical impulses produced by the animal by pressing shaped copper paddles and saddles against the specimen. Through this method, Faraday determined gasset y ortega filosofia and quantified the direction and magnitude of electric current, and proved the animal’s impulses were in fact electrical by observing sparks and deflections on a galvanometer.

Researchers at Yale University and the National tropico 5 electricity Institute of Standards and Technology argue artificial cells could be built that not only replicate the electrical behavior of electric eel cells, but also improve on them. Artificial versions of the eel’s electricity-generating cells could be developed as a power source for medical implants and other microscopic devices. [14] Ecology and life history Habitat

These fish have always been sought after by some animal collectors, but catching them is difficult, because the only reasonable option is to make the eels tired by continually discharging their electricity. [ citation needed] The fish’s electric organs eventually become completely electricity out in one room discharged, allowing the collector to wade into the water in comparative safety. [16]

The species is so unusual that it has been reclassified several times. When originally described by Carl Linnaeus in 1766, he used the name Gymnotus electricus, placing it in the same genus as Gymnotus carapo (banded knifefish) which he had described several years earlier. It was only electricity word search printable about a century later, in 1864, that the electric eel was moved to its own genus Electrophorus by Theodore Gill. [20]
