The electric eel is a freshwater fish found in the basins of the Amazon and Orinoco rivers. Like all species in the Gymnotes family, it has the ability to emit electric impulses. These animals have been studied since the 18th century and have inspired numerous research projects, such as Alessandro Volta's battery or more recently, in 2017, the development of hydrogels used in cardiac stimulators.

It lips turn into suction organs and it corneas gums allow it to take algae off the rocks. It acclimatized well in aquariums. Unfortunately, because of the demand for the aquarium trade, it is threatened by excessive fishing in its original environment.
