Photographer Alexander Semenov has a degree in Zoology with a specialization in invertebrate animals, particularly squid brains. Rather than fear the uncomfortable sting of jellyfish, like most of us do, Semenov seeks them out, discovering the natural beauty and magnificence of these creatures in their own environment through underwater photography.

After four years of practice, Semenov says, “When you’re working at something every day, you inevitably get a lot of experience. Eventually I began to get interesting photos—one or two from each dive.” His experience is evident in his final results. Through his photographs, Semenov is able to share a rare world with us by bringing the depths of the sea to the surface.

Fun fact: Jellyfish lifespans typically range from a few hours to several months.
