Glass Knifefishes
Sternopygidae
Glass knifefishes are fishes in the family Sternopygidae in the order Gymnotiformes. Species are also known as rattail knifefishes.
These fishes inhabit freshwater streams and rivers in Panama and South America. Many species are specialized for life in the deep (more than 20 m or 66 ft) swiftly moving waters of large river channels, like that of the Amazon and its major tributaries where they have been observed swimming vertically. Sternopygus species inhabit both streams and rivers.
