What do fish eat
Fish are not picky eaters and will consume a variety of food items. Their diet depends on the type of fish, as well as the water conditions where they live. In general, fish eat smaller fish, insects, worms, crustaceans, and mollusks. Some fish also eat algae and plant matter.
Fish are able to find food using their keen sense of smell. They can also see movement in the water, which helps them locate prey. Once they find food, they use their sharp teeth to bite off small pieces that they can swallow.
Fish play an important role in the ecosystem by providing food for other animals. They are also a popular choice for humans to eat, as they are a healthy source of protein and other nutrients.
How do fish breathe underwater
Fish have a unique respiratory system that allows them to breathe underwater. Their bodies are specially adapted to extract oxygen from the water and circulate it throughout their bodies.
Fish use a variety of methods to breathe underwater, depending on the type of fish and the environment in which they live. Some fish, such as sharks and rays, have gills that allow them to filter oxygen out of the water. Other fish, such as eels and catfish, have lungs that they use to breathe air from the surface of the water.
