Green anacondas have been known to eat pigs and peccaries
(which resemble pigs and can reach the weight of a smaller mini-pig).
Snakes have an incredible ability to stretch out their jaws and stomachs (although contrary to popular belief, they don’t actually move their jaws, they just stretch them out), so if they can eat animals several times wider than they are, they can’t.
