Animals have been a furtive ground of exploration for artists for millennia, and they have been represented elegantly in painting, sculpture, and photographs, to name just a few of the most popular media used in their depiction. This novel online collection from the California Institute of Technology features dozens of animals in a whole new light: Infrared. Recently, a team of researchers took photographs of animals with a thermal infrared camera in an attempt to offer visual evidence of the differences between warm and cold-blooded animals. On the site, visitors can view photographs of chickens, flamingos, swans, tigers, and seals taken with this type of camera. The photos give the ability to see the dramatic temperature variations within the body of any given animal. The site also features a nice essay on the significance of being warm or cold blooded, and how these conditions affect their activity levels and what environments they prefer.
