Who was Sedna and Where did animals in the sea come from according to Inuit legend?

In Inuit legend, Sedna was the keeper of the sea creatures the Inuit hunted.

As a young woman, against her father’s wishes, she married a dog and lived with him on an island. Angry at her betrayal, her father killed her dog-husband and compelled Sedna to sail home with him.

On the way, a storm threatened to overturn their boat. Hoping to calm the storm, the father decided to sacrifice his daughter by throwing her into the water.

Desperately, Sedna clung to the side of the boat, so her father cut off her fingers with a knife. According to Inuit legend, as they fell into the water, her first joints turned into whales, her second joints became seals, and the rest of the fingers transformed into walruses.
