Rhamphichthys

picture info	Rhamphichthys ''Rhamphichthys'' (''Rhamphos ='' Greek for beak and ''Ichthys'' = Greek for fish) is a genus of fish that includes the South American sand knifefish. These fish are eel shaped (or anguiform) with a distinct beak like snout which gave them their name. Like most other knifefish ''Rhamphichthys'' species have electrical organs that help them live in the murky waters of South America. Currently there are 10 recognized species of ''Rhamphichthys'', although many changes have been made in their taxonomy since their original discovery.

	Rhamphichthyidae Sand knifefish are freshwater electric fish of the family Rhamphichthyidae, from freshwater habitats in South America. Just like most part of the members of the Gymnotiformes group, they also have elongated and compressed bodies and electric organs. The long anal fin actually extends from before the pectoral fins to the tip of the tail. There is no dorsal fin. Teeth are absent in the oral jaws and the snout is very long and tubular. The nostrils are very close together. This group is sometimes known as the tubesnout knifefishes for this reason. They are nocturnal and burrow in the sand during the day. Genera According to FishBase there are only three genera in this family, but a comprehensive molecular study from 2015 showed that two additional genera belong here (formerly in Hypopomidae, marked with stars* in list), and this has been followed by recent authorities.

picture info	Gymnotiformes The Gymnotiformes are an order of teleost bony fishes commonly known as Neotropical knifefish or South American knifefish. They have long bodies and swim using undulations of their elongated anal fin. Found almost exclusively in fresh water (the only exceptions are species that occasionally may visit brackish water to feed), these mostly nocturnal fish are capable of producing electric fields to detect prey, for navigation, communication, and, in the case of the electric eel (''Electrophorus electricus''), attack and defense. A few species are familiar to the aquarium trade, such as the black ghost knifefish (''Apteronotus albifrons''), the glass knifefish (''Eigenmannia virescens''), and the banded knifefish (''Gymnotus carapo''). Description Anatomy and locomotion Aside from the electric eel (''Electrophorus electricus''), Gymnotiformes are slender fish with narrow bodies and tapering tails, hence the common name of "knifefishes".
