A small marine fish also called a sand eel or similar burrowing fish species.
Origin uncertain; possibly from Old English or Scandinavian roots referring to small burrowing fish. The term is primarily dialectal or regional.
The didal's ability to burrow into sand in seconds makes it nearly impossible to catch by hand—it's like the sand itself swallows it, which is exactly how it escapes predators in shallow water.
