A sand lance or sandlance is a fish belonging to the family Ammodytidae. Several species of sand lances are commonly known as "sand eels", though they are not related to true eels. Another variant name is launce, and all names of the fish are references to its slender body and pointed snout. The family name (and genus name, Ammodytes) means "sand burrower", which describes the sand lance's habit of burrowing into sand to avoid tidal currents.
