Etienne de France wrote and produced his 59-minute pseudo-documentary 2012 film "Tales of a Sea Cow". This film portrays a fictional 2006 re-discovery by marine biologists of a living population of the Steller's sea cow, an extinct sirenian species, off the coast of Greenland in the Arctic Ocean and Atlantic Ocean via analysis of sound recordings of their calls. The Steller's Sea Cow is known historically only from several islands in the Bering Sea, and prehistorically as a fossil at various sites on both the North American and Asian sides of the Pacific Ocean; no known Steller's Sea Cow has ever lived in the North Atlantic Ocean (although species of the related manatee do live in southern portions).
