Akhlut
In Inuit mythology, Akhlut is an orca spirit that takes the form of a gigantic wolf or a wolf-orca hybrid when on land. It is a vicious, dangerous beast that ventured onto land in order to hunt humans and other animals. Its tracks can be recognized because they are wolf tracks that lead to and from the ocean, indicating that the creature is waiting for prey under the water nearby. Often, dogs seen walking to the ocean and/or into it are considered evil. Little is known of this spirit other than that it changes from an orca to a wolf when hungry. Not many myths relate to it.
