With its strong jaws and swift bite, the snake seems to have the advantage in this matchup. But this nonvenomous garter snake is no match for a shrew armed with venom.

This garter snake can eat almost anything: rodents, reptiles, insects, fish, birds-and swallow them whole.

And this shrew would make a tasty snack.

But first, the garter snake has to catch one.

The shrew lives life in the fast lane.

Under stress, its heart can beat up to 1,300 times a minute.

To maintain all that energy, it eats constantly, digging up worms and grubs in this rich garden soil.

With its strong jaws and swift bite, the snake seems to have the advantage.

But the shrew's saliva can paralyze prey.

So in this fight, the first bite wins.

The shrew goes right for the neck.

The snake's muscles go slack as the venom takes hold.

And the shrew starts to eat him alive.

Size means nothing when you have the right weapons.
