Why do some snakes use venom instead of constriction?
Quick Answer
Venom gives snakes a fast way to immobilize or digest prey, especially when prey is dangerous or hard to hold. Constriction is another strategy, and different snake lineages evolved different hunting tools.
The Full Story
Venomous snakes inject toxins that can disable prey quickly, reduce the risk of injury, and sometimes begin digestion before swallowing. Constrictors, such as boas and pythons, kill by squeezing and stopping blood flow. Both strategies evolved repeatedly in snake evolution, showing that there is more than one successful path to hunting. Venom is especially useful when prey is fast, defensive, or difficult to subdue safely. The diversity of snake feeding methods is one reason they are such successful predators worldwide.
