What is the body part of a fish used for getting food?

The body part of a fish used for getting food is the mouth. The mouth of a fish is typically located at the front of the head and is used for taking in food, such as plankton, small fish, and other aquatic organisms. The shape and size of the mouth can vary depending on the type of fish and its feeding habits. Some fish, such as sharks, have large mouths with sharp teeth for capturing prey, while others, such as filter feeders, have smaller mouths and specialised structures for filtering food particles from the water.
