How much does a full grown adult diamondback rattlesnake weigh?

Answer 1

In 1987 I personally saw a large eastern diamondback that had been shot by security guards earlier in the day in a swamp near a medium caliber test range just northwest of Lakeland, Florida, less than 2 miles south of I-4. The snake's head had been severed, but I estimate the length of the snake's body was in the range of six to seven feet. What amazed me was the girth of the snake's body, which I estimate to be well in excess of twelve inches at the center. I have read many descriptions of the size and weight of eastern diamondbacks, some of which say a max of 15-20 pounds, some say up to 15 kg. I understand that this may appear to readers as an exaggeration, but I estimate that the body of the dead snake weighed somewhere in a range of 40 pounds of more. I work out regularly, so I know what 40 lbs. means. The head of the snake was very large, approximately six-plus inches across. Had I known then what I have read about these snakes, I would have urged the guards to take the specimens (there were two, the second also quite large but not nearly so) to an authority for examination, but unfortunately I did not. I'll be happy to answer relevant questions, but most of what I have is presented here.

Answer 2

It depends in the size of the snake. the largest ever measured was nearly 8 feet in length and weighed 15.4 kg (34 lb). The average weight of 9 laboratory-kept specimens was 2.55 kg (5.6 lb), with a range of 0.8 to 4.9 kg (1.8 to 10.8 lb).

Answer 3

From five to eleven pounds. Eastern diamondbacks are somewhat larger than the western species.

Answer 4

Adult timber rattlesnakes weigh, on average, between 500 and 1,500 g (1.1 and 3.3 lb), often being towards the lower end of that weight range.

Answer 5

An average western diamondback, 3-5 feet in length, would weigh 2-3 pounds. A large snake may weigh more than 20 pounds.

Answer 6

Six or seven pounds for a large one.
