I have seen many species of snakes on Nat Geo channel, but this was the first time i have ever seen a rattle snake upfront and so close. I have taken this shot during my visit to a Zoological park in Pune, there is an entire section for snakes of different species, Rattle snake was one of them. I used Tamron 70-300 lens on my nikon which helped me to get this closeup shot. . . . Save "YOUR SHOT"...!!!
