Scientist and photographer Igor Siwanowicz have made a name for themselves assigning the unbelievable variety of shapes, colors, and structures of creatures from the planet. His most pictures of unique caterpillars include wild variations like feathery blue spikes, curling burnt-orange horns, and long black whiskers. Siwanowicz also works as a neurobiologist in the Howard Hughes Medical Institute‘s Janelia Farm Research Campus in Virginia. He shares over ten years of his photography on photo.net.
