From the Ted Talk by Rebecca Tarvin: Why don't poisonous animals poison themselves?
Unscramble the Blue Letters
Bombardier beetles use the first approach. They store idtgrnieens for their pioson in two separate chambers. When they’re threatened, the valve between the crbamehs opens and the substances combine in a violent chemical ritcaeon that sends a corrosive spray shooting out of the glands, passing through a hardened chamber that protects the beetle’s internal tissues. Similarly, jellyfish package their venom safely in harpoon-like suteutcrrs called nematocysts. And venomous snakes store their flesh-eating, blood-clotting compounds in specialized cmeottrnpmas that only have one exit: through the fangs and into their prey or partdoer.

Original Text
Bombardier beetles use the first approach. They store ingredients for their poison in two separate chambers. When they’re threatened, the valve between the chambers opens and the substances combine in a violent chemical reaction that sends a corrosive spray shooting out of the glands, passing through a hardened chamber that protects the beetle’s internal tissues. Similarly, 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.
