Variations: Skate Mother; Fluxuskrímsl (Flake Monster); Vatnsandi (Water Spirit); Vatnaskratti (Water Devil)
Skate in Iceland are mystical creatures. Saint Peter recognized them as the holiest fish in the sea, and they are intimately connected with the number nine. A skate has nine good qualities and nine bad. It will watch over a drowned man for nine nights, and spend the next nine nights eating him. A skate will carry its young within her for nine months, then lie upon them for nine weeks, during which a stone grows within them. This stone, the “skate-stone”, could make a man invisible for one hour, or relieve labor pangs. Empty mermaid’s purses, or “Peter’s purses” as they are known, have lost their skate-stones.
Most terrifying of all is the Skötumóðir, or “Skate Mother”. Like the other Icelandic “fish mothers”, they are not necessarily skate themselves; in fact, some accounts describe them as evil whales that resemble skates. They are enormous and toxic to eat, with backs like mud-covered islands, and sport nine tails. Unlike regular skate, they have been found inland, in freshwater, and even on dry land.
There is always a swarm of skate swimming around a skötumóðir. As they are caught by fishermen, the sea seems to get shallower as the skötumóðir rises to the surface. Finally, the vengeful skate mother hooks its wings onto the gunwales of the boat, and drags it below the waves.
To evade a skötumóðir, prompt action is required. When the huge ray latches its wings onto the boat, they must be immediately chopped off with whatever sharp implement is handy. This will effectively neutralize the threat.
An enormous skate, no doubt a skötumóðir, was one of three monsters terrorizing people around Lagarfljót, lying in wait at ferry crossings. It was transfixed to the bottom of the river by a powerful sorcerer, and unless it has escaped, it is there still.
