Why should you be careful when you are by a piranha?

You should be careful when near piranhas because they are known for their sharp teeth and strong bite, which can be dangerous, especially if they feel threatened or are in a feeding frenzy. While most species are not aggressive towards humans, certain conditions can provoke them. Additionally, piranhas are often found in murky waters where visibility is low, increasing the risk of accidental encounters. Thus, exercising caution is essential for safety.
