Animal culture is when animals behave in a certain way that is passed down from generation to generation, just like humans have different cultures too. For example, some kinds of monkeys are known to be picky eaters and will only eat certain kinds of food. Scientists think the monkeys learned this behavior from other monkeys, and now they all do the same thing. Other animals, like whales, use special sounds or songs to communicate with each other, and scientists believe these sounds might be like special language that is passed on from whale to whale.
