Venomous snakes are reptiles that produce venom, a toxic substance used to immobilize or kill their prey. This venom is delivered through specialized fangs when the snake bites. Common examples of venomous snakes include the copperhead, rattlesnake, and king cobra. Their venom can vary in potency and effects, ranging from mild irritation to severe injury or even death. These snakes play an important role in their ecosystems by controlling populations of rodents and other small animals. While they can be dangerous to humans, most bites occur when the snake is accidentally provoked. Understanding their behavior and habitat can help reduce the risk of encounters.
