Reinhold Thiele painted this limber-looking blue shark for the book British Salt-Water Fishes.

I found it on Wikimedia Commons, but they got it from University of Washington’s Freshwater and Marine Image Bank, which seems like a wonderful collection of, you know, fish pictures. And boat pictures, net pictures, fishery pictures… you get the idea.
