This photo has been around a loooong time. It is of a Timber Rattler. Officially the world record is something like 6' 2". This photo and the details are featured in a recent Georgia conservation mag. If I recall correctly, this snake was unofficially measured at 6' 6". Which if it holds up, I suppose will be a new recoprd. I forget the weight, but I thin k it was something like 40# - 45# ????
To give an idea of the barf you can come across on the "net", this particular snake has been killed in at least 7 states that I "know" of. The largest "measurement" that I recall stated as fact in these BS postings was 11' 6" and weighing 94#. I have been in the southern woods for going on 5 decades now. I have come across maybe 8-10 Timber rattlers. By far, the largest Timber Rattle snake I have come across myself, I measured at just under 56". It had 14 "rattles" and the "button". Maybe weighed 15#, but that is a guess and probably high.
