If you’re wondering why they’re all black, aside from red, it’s the best colour to be in the deep sea if you don’t want to get spotted.
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.
This also applies to red-hued deep-sea creatures too, as the US National Ocean and Atmospheric Administraation (NOAA) explains:
“The black animals absorb all colours of light available, and the red animals appear black as well; there is no red light to reflect and their bodies absorb all other available wavelengths of light. Thus red and black animals predominate.”
Case in point:
Before we have a look at some more of these incredible creatures, let’s just put it out there that it sucks that these animals died because they were caught up in a fisherman’s net, and the best place for them is obviously back safe in their habitat.
But these images give us the opportunity to appreciate and learn more about life on Earth, and the more excited we are about the breadth of life that’s lurking in the depths of the ocean, the more likely researchers will be to get the funding they need to actually go down there and study them.
So here are some more of our favourite pics from Fedortsov, and you can see them all in his Twitter feed:
