The Ojibwe clans are a way to divide up the families, the roles, and the labor of life. Each totem (clan) is an animal spirit natives believe they descended from. The totem was passed down through the male line, and individuals could not marry someone in the same clan. There are 22 different listed totems. According to oral stories there were initially 6 including "crane, catfish, bear, marten, wolf, and loon." The additional 16 are the Reindeer, Merman, Pike, Lynx, Eagle, Rattlesnake, Moose, Black Duck or Cormorant, Goose, Sucker, Sturgeon, White Fish, Beaver, Gull, and Hawk.
