Photograph by @paulnicklen // A bowhead whale thrashes its 20 foot wide tail against the oceans surface creating a thunderous boom both above and below the water. Bowheads are the oldest living mammals on Earth. The older they get the more white their tails become. This very old whale could easily have been over 200 years old. They are also very susceptible to ocean noise. As sea ice coverage reaches an all time low, there is much interest in seismic testing for oil near their migratory routes and summering grounds. I have seen small motor boats displace over 50 whales out of a bay. What would the deafening sonic booms from oil exploration companies do to these whales? #followme on @paulnicklen and @sea_legacy to see these great whales underwater. #gratitude #whale #mpa #turningthetide
