The great David Bowie and his counterparts, sea slugsPictolic
In Tumblr there is a blog called Bowiebranchia, which compares photos of Bowie and gastropods. At first glance this comparison may seem odd, but as soon as you start to consider these pictures, everything falls into place. They're really similar.
Sometimes the similarity comes to such an extent that it may give the impression that the British rock singer and really was inspired by photographs of marine life to create his images.
