Over 80 percent of the planet’s oceans remain unexplored even though they represent the vast majority of the biosphere. One of them is photographer and deep-sea fisherman Roman Fedortsov from Russia who spends most of his time on fishing trawlers. Scroll down to go deep into the abyss, dear Pandas, and upvote the photos by Roman that you enjoyed looking at the most. Bored Panda reached out to Roman and he was kind enough to go into detail about his work and life. A small note of warning, dear Pandas: some of these undersea fish and other creatures look a tiny bit disturbing.
