Ophichthidae is a family of fish belonging to the order Anguilliformes, commonly known as the snake eels. The name "Ophichthidae" originates from the Greek words ophis ("serpent") and ichthys ("fish"). Snake eels are renowned for their burrowing capabilities, and their distinctive physique resembles that of a snake, characterized by elongated and cylindrical bodies. This family is widely distributed across tropical to warm temperate waters worldwide. They exhibit a remarkable versatility in their choice of habitats, occupying diverse environments ranging from coastal shallows and rivers to depths exceeding 800 m (2,600 ft). While most species prefer a benthic lifestyle, concealing themselves within mud or sand to seize their prey consisting of crustaceans and small fish, certain species demonstrate pelagic tendencies.
