Synodus intermedius, the common sand diver, is a species of fish in the lizardfish family, the Synodontidae, a basal ray-finned fish in the class Actinopterygii. Sand divers inhabit subtropical marine ecosystems, (37-17°N), including sandy- bottom areas on continental shelves, coral reefs, estuaries, bays, and reef structures.

But Synodus intermedius is also known as Yellow striped lizardfish, Caribbean lizardfish or Sand diver. The name of the genus Synodus comes from the Greek “syn” together and “odous”, tooth, with reference to the numerous small teeth growing very close to each other.
