Roman Fedortsov is a deep-sea fisherman based in the port city of Murmansk in Russia, which looks out over the Barents Sea – a relatively shallow sea that opens into the Arctic Ocean.
We like to say we know less about the ocean here on Earth than we do about the surface of Mars, because while we have a vague idea of its overall structure, we’ve only properly seen less than 0.05 percent of our oceans.
Imagine we discover an alien planet that’s teeming with life, and we’ve only explored an area the size of the Australian island Tasmania – that’s what we’re dealing with when it comes to the ocean.
But now, thanks to this awesome deep-sea diver and prolific tweeter, we’re finally getting a glimpse at what’s really down there. Fishing throughout the coastal Arctic ocean region, all the way to the coast of Morocco, Fedortsov takes to social media to share images of the deep-sea creatures that wander into his nets.
These creatures live in the ‘twilight zone’ of the ocean – otherwise known as the Mesopelagic – which extends from a depth of 200 to 1,000 metres (roughly 660 to 3,300 feet) below the surface.
Below the Mesopelagic is the bathyal zone, which spans from 1,000 to 4,000 metres deep (3,300 to 13,000 feet), at which point there is zero sunlight.
That means these guys are dealing with only the tiniest hints of light penetration, and because black absorbs every wavelength of light without reflecting any back, they’re effectively invisible in their natural habitat.
