The arched lower lip of a whale can often make it look like it is smiling! However, this isn't a "real" smile as the blubber in the head of the whale prevents the muscles of the face from reaching the surface.

During the high feeding season, it has been estimated that an adult blue whale can eat up to 40 million krill in one day. (Krill are shrimp like creatures).

Historically, a blue ribbon has been awarded for first prize.
