Colleagues at the Smithsonian have just added a fantastic new online exhibition to their website.  Called 'What You See When You Turn a Fish Inside Out' gives users the chance to strip away the exterior of a fish and take an x-ray peek at its insides. Great stuff!

The live exhibition at the museum, "X-Ray Vision Fish Inside Out" looks fascinating.  I wish I had a trip lined up to the USA...  View the online component.
