Rattlesnakes do not usually chase their prey but wait in ambush under a bush or other object for a prey animal to pass close by. They then strike out and inject venom. Once the animal has died the snake will follow the scent trail to its body and swallow it.
A rattlesnake may be a prey or predator. They eat small animals but are preyed upon by a number of creatures.
A rattlesnake can strike up to one-third of its body length when attacking prey or defending itself.
A rattlesnake can strike its prey from a distance of about one-third to one-half of its body length, which is typically around 2 to 4 feet.
A rattlesnake swallows it's prey whole
Birds of prey like hawks
"He chased like foxhounds chase their prey".
A bull snake eats a rattlesnake by overpowering it with its size and strength, then swallowing it whole. The bull snake is immune to the rattlesnake's venom, allowing it to safely consume its prey.
They chase it.
Rattlesnakes lie in wait for their prey, or hunt for it in holes. The prey is killed quickly with a venomous bite as opposed to constricting. If the bitten prey moves away before dying, the rattlesnake can follow it by its scent. When it locates the fallen prey, it checks for signs of life by prodding with its snout, flicking its tongue, and using its sense of smell. Once the prey has become incapacitated, the rattlesnake locates its head by odors emitted from the mouth. The prey is then ingested head-first, which allows wings and limbs to fold at the joints in a manner which minimizes the girth of the meal.
They hunt by sensing the heat given off by their prey - rodents.
A rattlesnake is both a predator and a prey. It feeds on a number of small animals and, in turn, is preyed upon by many carnivores and birds such as hawks, eagles, roadrunners, etc.
They chase after its pray.
