Storyboard Text

  • We are the majority of the population
  • Ahhh!
  • The snake has a hard time preying for us
  • There was a rat population living outside of a cave. The population's fur color was mostly brown due to the color of the ground.
  • There is water and it will be cooler inside of the cave so we can survive
  • Water snakes were the rat's predators and they would feast on whichever rat they saw first. If the rat had a more noticeable color, then the snake would have an easier time preying on them.
  • Ahhh!
  • There was always a low population of black rats, as they were always eaten by the snakes.
  • The bats have a hard time preying for us
  • One day, there was a drought and the rats could no longer live outside as it was too hot and there was no water available, so they scurried inside of the cave.
  • Inside of the cave, their predator were bats, and because they could see the lighter colored rats better, the brown rats did not survive while the black rats flourished.
  • The black rats flourished because they are harder to see due to their environment, while the brown rats were eaten by the bats.
