I blogged about this photo here --> Endangered Species Day
UPDATE (3/31/3011): This photo was originally uploaded in August of 2008 when most of you who now follow me had not discovered my photostream. It still managed to be selected for Explore on 8/18/2008 at Position 360. It continues as one of my most viewed photos with thanks to the search engines who give it much love.
