Rhamphichthys

Rhamphichthys is a genus of freshwater ray-finned fish belonging to the family Rhamphichthyidae, the sand knifefishes. 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.

==Etymology== Rhamphichthys combines the Greek rhámphos (ῥάμφος), meaning "beak" or "bill" and ichthýs (ἰχθύς), which means "fish". This is a reference to the snout forming a tube in these fishes.
