The Denver Museum of Nature and Science will be debuting a new exhibit on October 1, 2014. Whales: Giants of the Deep is an exhibit on tour from the museum of New Zealand Te Papa Tongarewa, a facility boasting one of the world’s largest marine mammal collections. The exhibit includes a gorgeous skeleton of a 58-foot sperm whale, one of 20 specimens set to be on display. The museum said visitors can crawl through a life-sized replica of a blue whale’s heart, touch whale teeth, listen to whale calls, and enjoy life-sized models and cool, rare artifacts. Sounds like such a blast. The exhibit is free with the $13 museum admission.
