Survival of the fittest is a phrase that rules the animal kingdom, meaning that even a creature as majestic as a baby humpback whale is prey for a stronger species. This video, captured at the Revillagigedo Islands off the western coast of Mexico, shows a young whale struggling against an attempt to force it underwater. According to Luis, who recorded this video, it was a group of Orcas that targeted the whale. Credit: YouTube/Luis Bringas
