Friday Fun: Five Gross and Goofy Body Facts

  1. A housefly dribbles spit onto its food. Chemicals in the spit break down the food. Then the fly can suck it up.
  2. When an archerfish is hungry, it spits at insects to knock them into the water. Then it swims over and gobbles up the prey.
  3. Leeches, ticks, vampire bats, and female mosquitoes all feast on fresh blood. And they depend on proteins in their spit to keep their food flowing.
  4. A giraffe’s favorite food, the acacia tree, has sharp, spiky thorns lining its branches. Luckily, giraffes make lots of thick, mucous-y saliva. The spit coats the thorns and protects the inside of the animal’s mouth.
  5. A komodo dragon’s saliva is deadly. It’s swarming with harmful bacteria that infect wounds made by the lizard’s sharp teeth. If the injured animal manages to escape, the komodo dragon follows the animal until it dies.
