From eyewitness accounts to last known photographs, there is evidence that suggests some of these creatures are still very much alive in the wild. The search is on for wildlife adventurer and biologist Forrest Galante, as he explores the real stories behind animals thought to be gone forever and tries to prove their existence so he can protect them and help them thrive again.
