Eastern diamondback rattlesnakes, though long, do not compare to the size of a lion. A lion stands multiple feet taller than an eastern diamondback rattlesnake. Compare the measly 10 pounds of this snake to the 550 pounds of a male lion — that’s a massive difference!
Speed and Movement

Although eastern diamondback rattlesnakes have an impressive striking speed, their traveling speed doesn’t compare to a lion’s. Afterall, lions travel at 50 miles per hour. However, they are still swift enough to startle an unsuspecting lion. If it gets close enough and perceives the lion as a threat, it could strike swiftly and land a bite.

An eastern diamondback rattlesnake can inject a powerful, deadly venom. All it takes is a single bite! If a lion happens to get too close, an eastern diamondback rattlesnake will use its warning rattle to let it know it’s gone too far and should retreat!
Offensive Capabilities

An eastern diamondback is limited to its strike, bite, and venom, whereas a lion has its size, powerful jaws, sharp teeth, and sharp claws to work with. However, a single bite from an eastern diamondback rattlesnake could do serious damage. It could inject enough venom to kill a full-grown lion.
Predatory Behavior

Lions usually hunt in prides, relying on group strength and skill to take down large prey (as big as wildebeests!). Snakes, even if they’re long and meaty, aren’t of particular interest to them. However, lions are obligate carnivores, which means if they’re hungry and there’s a meaty snack available, they may just go for it.
When lions hunt alone, they change their tactics. Instead of relying on their pride to take down large animals, they are super sneaky, crouching down behind tall grasses before ambushing their prey. In that sense, they are much like the eastern diamondback rattlesnake, which is generally solitary and waits quietly until prey is within striking distance.
As for eastern diamondback rattlesnakes, they typically feast on small mammals and birds. They don’t perceive lions as a food source.

So, who would win the eastern diamondback rattlesnake vs. lion battle? If an eastern diamondback rattlesnake manages to strike and bite a lion, injecting its deadly venom, it could potentially kill the lion. But most likely, a lion would win in a fight with an eastern diamondback rattlesnake. A lion is much too powerful and agile to allow a snake to get close enough to strike. The rattle is warning enough, and a lion has no interest in snakes. If, for some reason, these two animals encountered one another, the lion would completely overpower the eastern diamondback snake, tearing through its scaly body, crushing it, and rendering it unable to deliver its deadly venom.
