Arctic Tale

Arctic Tale is a 2007 documentary film from the National Geographic Society about the life cycle of a walrus and her calf, and a polar bear and her cubs, in a similar vein to the 2005 hit production March of the Penguins, also from National Geographic. It was directed by Adam Ravetch and Sarah Robertson and is narrated by Queen Latifah. The animal characters named in the movie, Nanu the female polar bear and Seela the female walrus, are based on composites of animals in their species, as noted at the end of the film.

At the outset of the movie, Nanu emerges from the cave where she was born along with her brother, just born as well, and their mother. The two polar bear cubs play in the snow for a while until returning to their snow cave. The next day, the cubs start learning from their mother how to survive in the wild. One of the first things they find out by watching their mother is to stay away from grown male polar bears who are apt to kill them.Seela is shown in the water just after birth with her mother and Auntie who helps protect the walrus calf during her early life. For her first life lesson, Seela is taught how to hoist herself onto an ice floe from the water without any help except watching her mother do the same. During this time, Auntie watches for predators. When a male polar bear comes along and starts swimming towards the walruses, Seela and her mother try to get away from him, but must rely on Aunties help to stave off the polar bears attack. ........
