Protected by its isolation, the wildlife of Cuba has remained naturally preserved, untouched, and unexplored. Through a special arrangement with the Cuban government, unprecedented access was granted to film the astonishing diversity of life on the island, much of it virtually unknown until recently. For the first time, the rest of us will have the opportunity to see the butterfly bats, leaping crocodiles, the tiny bee hummingbird, and the largest colony of Caribbean flamingoes in the world.
