Russian photographer Alexander Semenov’s photographs urge viewers to take a closer look at lesser known underwater life.
These pictures feature the various types of “sea butterflies”, with transparent bodies which seem to glow.
Placed against a black background for contrast, the viewer can also see the orange insides of these sea creatures, as though they have exposed their “hearts” for all to see.
Check out the rest of these photographs below.
