Print Electric Eels
Spanish: Las Anguilas Eléctricas
1 Electric eels, measuring up to nine feet long and dwelling in slow-moving rivers of South America, bear a name that is destined to cause confusion. That is because electric eels are not really eels! Instead, they are close relatives of knifefish.
2 So, why are electric eels not true eels, given that both animals have long, cylindrical bodies and continuous fins running along their undersides? Here are some of the reasons:
- True eels (such as conger eels and moray eels) have dorsal fins on their backs, whereas electric eels do not.
- True eels spend part or all of their life in oceans, whereas electric eels are lifetime members of the freshwater biome.
- True eels have teeth, whereas electric eels do not.
