Since first covering the photography of Russian biologist Alexander Semenov back in January his self-directed “Underwater Experiments” series has continued unabated as he releases other-worldy shots of the Earth’s most elusive creatures almost daily. Again and again Semenov captures some of the most jaw-dropping photographs of underwater life I’ve ever seen, most frequently an animal called lion’s mane jellyfish (Cyanea capillata) which is the largest known species of jellyfish in the world. What you see here only scratches the surface of his work over the last couple of months, definitely urge you to get lost in his underwater gallery. Via Colossal.
