Sea Angels and Sea Butterflies: The Horrible Truth…
Russian photographer Alexander Semenov captured these beautifully delicate sea creatures known as Sea Angels and Sea Butterflies. By capturing these little beauties on a black background, their transparent bodies seem to glow with a soft orange color.
Sea angels are a form of sea slug while sea butterflies are a form of sea snail. Sea butterflies have broader bodies and a shell, which some of them retain. But there is a hidden, shocking truth about these lovely luminescent creatures of the sea…and, oh, the horror!
The sea angels eat the sea butterflies.
The angels have terminal mouths common to mollusks, and tentacles to grasp their prey, sometimes with suckers similar to cephalopods. Their “wings” allow sea angels to swim much faster than the larger (usually fused) wings of sea butterflies. Nature can be cruel, but an angel has got to eat!
