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.
Jaguars are built for surprise attack, not speed. They can have bursts of speed up to 30 mph for a very very short time. Jaguars are thick and bulky with strong short legs. In a full run, they can achieve speeds between 25-30 mph. Quite a bit of a contrast to their cheetah cousins. About 60 MPH.
