Proverbs often include animals. Let's look at some examples from two countries. The first one is from Thailand. "Don't ride an elephant to catch a grasshopper." When you are doing a small job, a big tool is not useful. The second one is from Brazil. “In a piranha-filled river, an alligator a-fill swims backstroke." Before you get in trouble, prepare for danger and protect yourself. Proverbs from different countries often include familiar local animals. Because of their images, people easily understand the messages.
