This undated handout picture taken by Dave Brosha and released by the Australian Antarctic Division on April 11, 2017 shows research on whales being conducted in the Gerlache Strait in Antarctica. Whale cams have revealed the secret feeding habits of the giant mammals in frozen Antarctica, details on their social lives, and even how they must blow hard to clear sea ice to breathe.
