* Their teeth and jaws: Snakes have sharp, backward-curving teeth that help them grab and hold onto their prey. Their jaws are also incredibly flexible, allowing them to swallow animals much larger than their heads.

* Their hunting strategies: Snakes use a variety of strategies to hunt, including constricting their prey, injecting venom, and using their speed and agility to ambush their victims.
