Pretty sure this is not allowed as penguins are not "domestic fowl", and I created these on the computer, but thought would share anyway.
They are images from a paper looking at the airsacs of 3 species of penguin and how the airsac size enabled the penguins to dive so deep.
( http://www.ncbi.nlm.nih.gov/m/pubmed/25740902/. If anyone is interested) .
Here are just the lungs and airsacs. The images were created from working on 3D CT scans of the penguins. Took months.
