Muraenidae

Muraenidae is the family of moray eels, a group of eels whose members are found in waters around the world. The family holds approximately 200 species placed in 16 genera. Almost all of them live in the sea, but several species are regularly seen in brackish water and a few are found in fresh water. The English word moray dates back to the early 17th century and is believed to derive from the Portuguese moreia, which itself comes from the Latin murena and the Greek muraina, the old names of the Mediterranean moray. In the Atlas the family sits among the fish families, beneath the order of eels, Anguilliformes.
