Variations: Auseq
Tales from Greenland, notably Aasiaat, tell of a gigantic maggot called Quvdlugiarsuaq. It is so big that the legend of Aqigsiaq tells of a dwelling place that survived an entire winter on the blubber of one quvdlugiarsuaq.
The Auseq is a similar creature described as a giant caterpillar. It is dangerous to humans.

The Sermilik, “ice-clad”, is an enormous and highly dangerous polar bear found in the seas around Aasiaat in Greenland. Unlike the bears it resembles, it has very long fur completely covered with ice. Four lumps of ice at the surface are in fact the four paws of a sermilik lying in wait, and young hunters are warned never to paddle near those.
