The sand maggot was a carnivorous animal native to Safehold, looking much like a six-legged slug, which haunted beaches just above the surf line.
Sand maggots did not normally take living prey, although they had no objection to devouring the occasional small creature which strayed into their reach. Their natural coloration blended well with their sandy habitat, and they normally concealed themselves by digging their bodies into the sand until they were completely covered or only a small portion of their backs showed.
