Interesting facts about the Zitteraal

  • The Eel or Electrophorus electricus describes a species within the New World Knifefish that populates rivers in South America.
  • The electric eel can generate surges of more than six hundred volts.
  • He owes this ability to his special musculature, which is made up of more than six thousand electrocytes.
  • These elongated, superimposed cells are activated in sequence by nerve impulses in the brain, so that a tension can be built up between the positive pole at the head and the negative pole at the tail.
  • Shivering eels can only see very badly and therefore can not detect potential prey in this way. In the murky mud of the waters, they continuously build up power fields of about ten volts. When a fish passes, the electrical voltage changes. In this way, the Zitteraal becomes aware of the prey.
  • Its own organs are protected from electric shock by a thick surrounding layer of fat.
  • The eel eel is not one of the eels, but is referred to as such due to its body shape.
  • It is cylindrical in shape and can grow up to three meters long. Large specimens weigh up to twenty kilograms.
  • The eel has only one anal fin running all over the body, but no abdominal, tail or dorsal fins.
  • Due to its inconspicuous brownish or greenish color it is well camouflaged in the mud.
  • He lives in predominantly oxygen-poor waters and therefore has to swim about every ten minutes to the surface of the water to absorb oxygen through blood vessels in his round mouth.
  • In the mud at the bottom, the electric eel buys various fish. The young shaking eels live mainly on amphibians and aquatic insects that live in muddy grounds.
  • The electric fields are also used by the Zitteraal to find partners.
  • After mating in the fall, the male takes care of the brood care. It builds a nest from aquatic plants in which the eggs develop and later hatch the larvae, which are about one centimeter long.
  • The Zitteraal is not an aggressive fish that basically shuns people. Electric shocks are therefore very rare, but in extreme cases can lead to severe muscle cramps and respiratory arrest.
  • The life expectancy of the electric shaker is on average twenty years.
