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.
