I. Physical Features

Electric eels are non truly eels. they are really ostariophysians. but have a strong physical resemblance to true eels. . An electric eel is largely tail. The internal variety meats are compressed into the front tooth ( front ) 1/5th of the organic structure. and the remainder of the fish consists of the long. electricity-producing tail. The tail contains the electric variety meats: Sachs’ organ. Hunter’s organ. and chief organ. Widening down the full tail part is an extended anal five.

There are no dorsal or pelvic fives. An grownup eel can make any size from six to nine pess in length an weigh up to sixty lbs. It is cylindrical in form with a somewhat flattened caput and big oral cavity. They do hold gills. though it is non their primary beginning of O consumption. A midst. slimed tegument covers the full organic structure. The tegument is used as a protective bed. frequently from their ain electrical current that is produced.

Electric eels range from grey to brownish/black in colour with some xanthous colour on the bottom of the organic structure and have bantam graduated tables. Electric eels do non hold dentitions. enabling them to get down their quarry easier. The eyes are bantam. and as this fish ages. its vision diminishes.

II. Physiological Features

The Main and Hunters’ variety meats are the high electromotive force manufacturers. used for protection. fright physiological reactions and stupefying quarry. The Sachs’ organ is capable merely of bring forthing low electromotive force pulses – its intent is chiefly electro communicating and pilotage. . Electric variety meats are made up of cells called Electrolytes. Some scientists believe these cells are derivative of a muscle-cell since nervus cells synapse onto them and they behave much like a muscle-cell post-synaptically. However. they are unlike musculus cells in that they don’t contract. Flat and disk-like. the electrocytes are stacked in a sequence with the caput as the positive pole and the tail as the negative pole. Each electrocyte generates. 15 Vs. which is a really little sum. However. when 4. 000 electrocytes are lined up bring forthing electricity at the exact same clip at. 15 Vs each. the daze peers at least 600 Vs. which can paralyse or kill a human. particularly after repeated dazes.

At remainder. the Na+K+ pump. concentration and electrical gradient keeps the interior of the electrocyte at a resting potency of. 08 V. When the electric eel electrolocates its quarry. the encephalon sends a signal through the nervous system to the electric variety meats. Acetylcholine is dropped onto the electrocyte which binds to the corresponding receptor on the ion. This opens the ion channels of the cell. leting Na+ to hotfoot in. The cell so depolarizes. momently change by reversaling the charge. and fires. Since the electrocytes are lined up. current flows through like a battery. breathing a charge. However. they must all discharge at the same clip. The electric eel’s design resolves this at the neural connexions by detaining the signals and action potencies. The closer connexions have longer and thinner tracts. which decelerates the signal and allows all electrocytes to synchronise their discharge.

III. Habitat

The electric eel may be found in the basins of both the Amazon River and Orinoco River. every bit good as the environing countries. They live in Murky. low-oxygenated fresh water watercourses and pools. The Amazon river home ground has a low concentration of dissolved O in the H2O. For this ground the eel surfaces often to derive sufficient O for respiration. Up to 80 % of the entire O consumption is from the ambiance. as opposed to the 20 % extracted by the gills. Emission of C dioxide is done chiefly through the tegument ( 80 % ) . but a little sum of C dioxide is emitted through the oral cavity ( 20 % ) .

The electric eel seems to hold adapted and evolved to its preferable environment. It is able to swim frontward and rearward with its undulating anal five. This allows it a better sense of its milieus. An electric eel will decease if left in H2O for more than 20 proceedingss. The nebulose H2O does non make ocular obstructions for the fish either. Not merely is the electric eel nocturnal. a to the full adult fish can barely utilize their beadlike eyes. Although the young person can see. the grownups become progressively unsighted due to the changeless exposure to the generated electrical field. Electric Fieldss from other fish are generated irrespective of whether or non they are electrogenic. The usage of any musculus creates an electric field. so the contractions of a bosom could be detected in another fish. The eels can turn up objects accurately by mensurating frequences and amplitudes on different parts of the organic structure every bit good as inactive electricity. caused by flow of H2O against the underside of the river.

By utilizing its ain electric organ discharge ( EOD ) and feeling differences in the current around itself. the eel is able to infer the conduction of any encompassing objects. another manner of pilotage and obstruction sensing. In add-on. the EOD from other electrogenic fish can be used for communicating.

IV. Assorted

Electric eels have been reclassified several times. Originally a species in Gymnotus. it was subsequently given its ain household Electrophoridae. and merely demoted to a genus of Gymnotidae alongside Gymnotus. The electric eel requires scientific licenses to obtain. It would be highly harmful for worlds and animate beings if released into waterways. Electric eels are one of the preferable topics for research of the enzyme. Acetylcholinesterase ( AchE ) . The electric eel is used for malignant neoplastic disease research every bit good. Occasionally. they are eaten by locals of the Amazon country. They are. nevertheless. normally avoided due to the electrical dazes that can be given out up to eight hours after decease. Although there is no commercial value. the electric eel has been a changeless beginning of survey for many old ages. The scientific community is really interested in analyzing the electrical capablenesss of electric eels. Electric eels can fatally electrocute a Equus caballus. A human can defy one discharge. but would non last several.
