Microdesmidae - wormfishes

Wormfishes are small, elongated fishes with one long, continuous dorsal fin and a protruding lower jaw. They are related to gobies and are likely to be mistaken for an elongated goby or an eel. They inhabit shallow waters from coral reefs to estuaries and often burrower into soft sediments. They are more likely to be seen at night around lights than during the daytime. Fishermen sometimes may use them as bait.
