INFO:

ROV Hercules captured this footage of stunning deep sea columnar basalt while diving on ancient volcanos around 1,700 meters deep in a canyon North of Molokai. Basalt is an igneous rock that, as lava, cools in a particular way that creates these unique hexagonal columns. Keep watching, and you’ll even glimpse a monkfish (also known as a goosefish) sitting on these geological wonders. These anglerfishes in the family Lophiidae are always crowd-pleasers due to their “grumpy” looking facial expressions.
