This is a Brown Recluse Spider Photograph. Brown Recluse Spiders are one of three spiders in the United States considered harmful. A Brown Recluse Spider bite will swell and become red. Eventually the flesh will begin to dissolve. Unless treated quickly you will have permanent scars and tissue damage. Brown Recluse Spiders do not often kill humans but the effects of their vemon leaves lasting permanent damage. I took these Brown Recluse Spider Photographs using a Canon 5D Mark II camera and a Canon MP-E 65mm 1x-5x lens.
