Kiviak is prepared by fermenting 300 to 500 auk birds into a bag made of seal skin and covered in seal fat.
The auk-filled seal skin is left to ferment between 3 and 18 months.
The seal's fat acts as a tenderizer and preservative, enabling people to eat the birds raw, including their bones.
Many eat kiviak by biting off the bird's head and then sucking out the juices inside.
Kiviak is exceptionally pungent and reportedly tastes like matured cheese.
Kiviak is considered a special treat to celebrate weddings, birthdays, Christmas and other special occasions.
