  • Garter snakes eat slugs, fish, and other small animals. Some snakes eat certain types of prey more often than other types.
  • The prey preference trait determines what type of prey a garter snake usually eats. For example, a snake with a slug preference will eat mostly slugs, but a snake with a fish preference will eat mostly fish.
The table below describes a possible population of garter snakes over a time period long enough for natural selection to occur. The table shows prey preference in the population at the start and end of this period.
