Apterichtus is a genus of fish in the family Ophichthidae (snake eels). Many of its species are called finless eels.
The name literally means "finless fish" in Greek, from apteron (‘no-fins’ < privative a + pteron ) and ichthys (‘fish’). [1]
There are currently 18 recognized species in this genus:
Ophichthidae is a family of fish in the order Anguilliformes, commonly known as the snake eels. The term "Ophichthidae" comes from Greek ophis ("serpent") and ichthys ("fish"). Snake eels are also burrowing eels, they are named for their physical appearance, they have long, cylindrical, snake-like bodies. This family is found worldwide in tropical to warm temperate waters. They inhabit a wide range of habitats, from coastal shallows and even rivers, to depths below 800 m (2,600 ft). Most species are bottom dwellers, hiding in mud or sand to capture their prey of crustaceans and small fish, but some are pelagic.
Gymnothorax is a genus of fish in the family Muraenidae found in Atlantic, Indian and Pacific Ocean. With more than 120 species, it the most speciose genus of moray eels.

Brachysomophis is a genus of eels in the snake eel family Ophichthidae.
Callechelys is a genus of eels in the snake eel family Ophichthidae. It currently contains the following fifteen species:
