Monsters from the Abyss...

What I never realised was that Six Gills are among the top 4 biggest predatory fish, comparable to the Tiger Shark in size! These impressive looking, green-eyed monsters have carved out a niche for themselves at depth, and are obviously successful predators in this realm.
Dean would sample DNA, measure and satellite tag the animals before helping them on their way back down to the depths. This picture is of National Geographic's Brady Barr helping a Six Gill back down to the abyss.
