Many snakes and jellyfish are poisonous

jellyfish package their venom safely in harpoon-like structures called nematocysts.And venomous snakes store their flesh-eating, blood-clotting compounds in specialized compartments that only have one exit:through the fangs and into their prey or predator.Snakes also employ the second strategy:built-in biochemical resistance.Rattlesnakes and other types of vipers manufacture special proteins that bind and inactivate venom components in the blood.
