Gymnotides Teleosts Fishes. Vertebrates Animal Kingdom. Wildlife. Fauna. Zoology.

They are fish that live exclusively in South American rivers and lack dorsal and pelvic fins.

Many species have electrical organs whose function is not only defensive, but also serves as a sensory system to recognize individuals of the species itself.

Everyone has a short head, the abdomen in the front of the body and the anus almost behind the throat, since the five-sixths of the animal are occupied by the tail with the electric organs.

Typical species:

Gymnast or electric eel (more than 1 m)

The electric organs of the electric gymnast are highly developed and house a potential of up to 600 volts, with an intensity of one amp, enough to incapacitate a man.
