However, ''margygr'' literally means something like "mer-troll",<ref name="jon_arnason-eng-vol2-intro"/> and in medieval tradition, the ''margygr'' is more of a "sea monster"<ref name="sayers"/> or "sea-ogress".<ref name="laity"/>{{Refn|Also "giantess who emerges from the sea",<ref name="borovsky"/> and "described.. as disgusting trolls".<ref name="bugge-tr-schoefield"/>}}

According to a version of the ''[[Óláfs saga helga|Saga of St. Olaf]]'' ([[Olaf II of Norway]]) the king encountered a ''margygr'' whose singing lulled voyagers to sleep causing them to drown<ref name="thorpe2-p027-norw"/><ref name="olafs_saga_helga-flateyjar"/> and whose high-pitched shrieks drove men insane.<ref name="sayers"/><ref name="olafs_saga_helga-flateyjar"/> Her physical appearance is described thus: "She has a head like a horse, with ears erect and distended nostrils, big green eyes and fearful jaws. She has shoulders like a horse and hands in front; but behind she resembles a serpent".<ref name="olafs_saga_helga-flateyjar"/><ref name="bugge-tr-schoefield"/> This ''margygr'' was also said to be furry like a seal, and gray-colored.<ref name="olafs_saga_helga-flateyjar"/><ref name="borovsky"/>
