Qalupalik is an Inuit mythological creature. It is a human-like creature that lives in the sea, with long hair, green skin, and long fingernails. The myth is that qalupaliks wear an amautiit (a form of pouch that Inuit parents wear to carry their children) so they can take babies and children away who disobey their parents. The story was used to prevent children from wandering off alone, lest the qalupalik take them children in her amautik underwater and keep them forever.
Qalupaliks are said to make a distinctive humming sound; therefore, they can be heard before they appear.
In Helix: "Survivor Zero" (season 1, episode 7), Anana, an Inuit policewoman whose brother Miksa went missing when they were children and who is investigating the Arctic biostation as the possible location where 31 stolen children were taken, tells Sergio Ballesaros she and other children were cautioned to stay near their people's hunting sites, lest the Qalupalik steal them; she likens the Qalupalik to the bogeyman. Sergio, in turn, confides that children from the favelas in his hometown, Espírito Santo, Brazil, also went missing and implied he was one of them.
