the blue planet series be and without a doubt and one of the great documentary ever make on the ocean . for five year and filmmaker work tirelessly on the series and get footage that have never be see by anyone ( i. e. in the title and the deep . ) i highly recommend you watch this series . to see the angler fish outside of the small picture show in textbook be truly a treat and but only a needle in the vast haystack of the sea that blue planet cover . from the open ocean to tidal pool and coral sea to the deep dark part of the ocean itself and the bbc take the viewer on an almost magical journey through the ocean . i have to admit and one of my early dream in life be to be a marine biologist and and after see this series and the dream be revive . i have study the ocean of this world for year and and have see countless documentary on coral reef and dolphin and whale and crustacean . but in all and no one have manage to capture the life beneath the wave quite as well a this group of people . watch the blue planet series in it entirety and i promise you would not regret it .
