WASHINGTON -Fish are often classed as ugly , slimy creatures but these latest images reveal their inner beauty.  Each of the marine specimens have been bleached to make the skin clear and then stained to expose their complex and elegant skeletons.  They include the Spiny Lumpsucker, the Little Skate and the Butterfly Ray and form part of the Cleared exhibition due to go on display in Seattle in March. 
The project was created by Professor Adam Summers, associate director of Comparative Vertebrate Biomechanics at Washington University. He collected the specimens from various fisheries, with many having died during scientific studies. One study, for example, had focused on the developmental trajectory of the fish skeleton.
