A predator is an animal that hunts and eats other animals for food.
When people talk about predators, they often mean wild animals like lions or sharks. But sometimes they use the word to describe a person who takes advantage of someone else, like a business that preys on vulnerable customers with unfair prices. In general, if you think of something as a predator, it's likely something or someone that's strong and has power over others, and might not always have their best interests at heart.
Any animal or other organism that hunts and kills other organisms (their prey), primarily for food.
