Genres and Topics
Movies starring animals or in which animals are an important part of the story. In some cases, particular animals -dogs, horses, sharks, insects, etc.- have their own topic.
Topics are sub-genres and/or themes of any kind (romantic comedy, buddy, sports, etc.) that describe the plot of the movie you are looking for. Topics, however, are not keywords. If you search for a topic like "shark", for example, only movies in which sharks play a significant roll will appear, such as 'Jaws'. But not every movie that has a shark in it will be listed.
