Constrictor snakes usually are not aggressive and flee when confronted. They hunt for food but do not attempt to make a meal out of any creature that is too large to constrict.

Combat

Constrictor snakes hunt by grabbing prey with their mouths and then squeezing it with their powerful bodies.

Constrict (Ex)

On a successful grapple check, a constrictor snake deals 1d3+4 points of damage.

Improved Grab (Ex)

To use this ability, a constrictor snake must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can constrict.

Constrictor Snake, Giant

Giant constrictor snakes are more aggressive than their smaller cousins, principally because they need a great amount of food to survive.

Viper snakes rely on their venomous bite to kill prey and defend themselves.
