Jelly and I scream: The jellyfish is beautiful, but deadlyIt is a freezing landscape of ice and snow.
But venture a few metres under the surface, as diver and photographer Alexander Semenov did, and you enter the dream-like world of translucent 'lion's mane' jellyfish.
The marine biologist Alexander Semenov has spent more than two years in the hostile environment of the ultra-remote White Sea Biological Station, on the western coast of Russia.
Whenever he gets down-time, he floats his way beneath the surface, to capture images of the beautiful, if occasionally painful, creatures of the deep.
Russian biologist Alexander Semenov's 'Underwater Experiments' series follows the colourful and majestic beauty of the lion's mane jellyfish ('Cyanea capillata')
T lion's mane jellyfish is the largest (known) species of jellyfish in the world - and has been seen to grow seven feet in lengthThe underwater photographer breaks through arctic sea ice dropping into a cold -2C water - although still warmer than the -30C world up above.
Located in the north east Atlantic Ocean it is twice the size of Denmark and is only recently being explored by divers attracted by its crystal clear waters that allow divers to see an astonishing 40 metres underwater.
He has documented striking differences between these species who have evolved cut off from their cousins that live in warmer waters elsewhere in the world.
One of the lion's mane jellyfish comes up to the surface: In general the jellyfish remain within 20 metres of the surface
Although these jellyfish pack a sting, generally they just cause a swelling pain their stings stings are not generally known to be fatalsource: dailymail
