This quiz is not for the faint of stomach. But think of how horrible our stomachs would feel if we could not vomit when we have eaten something that is bad for us or too much food for our body to handle. Throwing up, or regurgitation, also serves some other purposes in the animal kingdom. Can you match the animal that goes with each fact?
GREAT BLUE HERON
1. Because this animal cannot vomit, it is extremely vulnerable to poison.
2. Look out below if you cause this youngster stress. It’s known to regurgitate on harassers below its nest.
3. Stand back! This animal can spurt its vomit of decaying and rotting prey up to 10 feet when it feels threatened.
4. This animal frequently swallows its prey whole. The parts of the prey that cannot be digested — bones, feathers, teeth — and might harm the animal’s digestive tract, are regurgitated in a pellet. These pellets help biologists learn what this creature has been eating.
5. This animal is known to regurgitate its food when it is stressed (which helps it to escape more quickly) or when it has swallowed a prey that is too large for its body to handle.
6. This animal uses regurgitation and evaporation to turn nectar into honey.
7. These parents regurgitate pre-digested food for their youngsters until they are old enough to eat a whole fish.
8. This animal does not have teeth or chewing mouth parts. Its sponge-like tongue can suck up liquid. It regurgitates some food and saliva, which provides an enzyme to break down non-liquid food into something it can slurp up.
9. This animal regurgitates saliva while eating its meal of blood. The saliva is an anticoagulant, a substance that prevents blood from clotting and clogging up the tube that this animal uses to suck the blood.

3. Turkey Vulture
6. Honey Bee
