Abstract The banded knife fish Gymnotus carapo is among the most widely distributed, broadly adapted eurytopicand phenotypically variable fish species in South America, with a geographic range of about 14 million km 2from the Llanos of Venezuela to the Pampas of northern Argentina.

Entered by Torres, Armi G. The banded knife fish Gymnotus carapo is among the most widely distributed, broadly adapted eurytopicand phenotypically variable fish species in South America, with a geographic range of about 14 million km 2from the Llanos of Venezuela to the Pampas of northern Argentina. Like other Gymnotids, it produces a weak electric field using specially-adapted muscle tissue located towards the tail.
