"Whales: Giants of the Deep" runs through January 16, 2012.
The exhibition explores the evolution of the whale from land mammal to the giant creatures we know today. Whale skeletons include some that are 38 and 58 feet long. There are also interactive games and a sound chamber for whale songs. Children can even climb through a life-size replica of the heart of a blue whale.
