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, as 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.
The superorder Elopomorpha contains a variety of types of fishes that range from typical silvery-colored species, such as the tarpons and ladyfishes of the Elopiformes and the bonefishes of the Albuliformes, to the long and slender, smooth-bodied eels of the Anguilliformes. The one characteristic uniting this group of fishes is they all have leptocephalus larvae, which are unique to the Elopomorpha. No other fishes have this type of larvae.
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.
Cathorops is a genus of catfishes in the family Ariidae found in the Atlantic and Pacific Oceans. These species are found in the eastern and western Central and South America in brackish and freshwater habitats. This genus is a strongly supported clade of this family. It consists of a natural group in which the monophyly is well-defined by morphological and molecular evidence and the genus probably includes several unrecognized species from both American coasts.
Gorgasia is one of the two genera that belong to the subfamily Heterocongrinae. This genus is classified by the behavioral pattern of burrowing 75% of their bodies in the sandy substrate they live in and protruding their upper body into the water current above, giving the appearance that they are planted into the ground. This protruding behavior serves a multipurpose functionality to their survival.
The garden eels are the subfamily Heterocongrinae in the conger eel family Congridae. The majority of the 36 known species of garden eels live in the Indo-Pacific, but can be found in warm ocean water worldwide. These small eels live in burrows on the sea floor and get their name from the behavior of poking their heads from their burrows while most of their bodies remain hidden. Since they tend to live in groups, the many eel heads "growing" from the sea floor resemble the plants in a garden. They vary in color and size depending on the species. The largest species reaches about 120 cm (47 in) in length, but most species do not surpass 60 cm (24 in). Garden eel colonies can grow as large as one acre in surface area and number up to several thousand individuals.
Apterichtus is a genus of fish in the family Ophichthidae. Many of its species are called finless eels.

It inhabits shallow waters where it burrows in sand; the burrows are sometimes exposed during low tide. It can reach a maximum total length of 82.5 centimetres, but more commonly reaches a TL of 60 cm.
Bascanichthys congoensis is an eel in the family Ophichthidae. It was described by Jacques Blache and Jean Cadenat in 1971.

Males can reach a maximum total length of 62.3 centimetres.
The Round sand-eel is an eel in the family Ophichthidae. It was described by Seth Eugene Meek and Samuel Frederick Hildebrand in 1923. It reaches a maximum length of around 88 cm. It is distributed throughout the Eastern Central Pacific; inhabiting shallow, sandy bottoms.
The Panama sand-eel is an eel in the family Ophichthidae. It was described by Seth Eugene Meek and Samuel Frederick Hildebrand in 1923. It is a marine, tropical eel which is known from the eastern central Atlantic Ocean, including the Gulf of California, Mexico, Costa Rica, Panama, and Nicaragua. It dwells at a maximum depth of 30 metres (98 ft), and inhabits sandy sediments, sometimes in estuaries and mangroves. Males can reach a maximum total length of 76 centimetres (30 in).
Dalophis boulengeri is an eel in the family Ophichthidae. It was described by Jacques Blache, Jean Cadenat and Alfred Stauch in 1970.
