Ray Troll discusses his fish-based art, which brings a street-smart sensibility to the worlds of ichthyology and paleontology. From his tree-top studio, high above the Tongass Narrows in rainswept Katchikan Alaska, Ray Troll draws and paints fishy images that migrate into museums, books and magazines and onto t-shirts sold round the globe. Over the years, he has done artwork for various conservation organizations including the Sierra Club, Greenpeace and the Southeast Alaska Conservation Council.
