End systolic volume (ESV) â The amount of blood still in the. ventricles after the contraction is complete. End diastolic volume (EDV) â The amount of blood in the. ventricles after they have filled but prior to the beginning of. the contraction.
This is the fastest form of travel for most snakes, but rattlesnakes donât engage in this style of locomotion often. Rattlesnake speeds have not been specifically measured, but they likely travel at about 2 to 3 miles per hour in very short bursts. In comparison, the fastest humans can run up to 28 miles per hour.
Weight: Using a formula of length-weight relationships, a seven-foot wild rattler would weigh about 15 pounds and an eight-foot snake would weigh 23 pounds. I next investigated Texas rattlesnakes and discovered the two largest rattlesnakes found in Texas are the Western Diamondback and the Timber Rattlesnake.
