How do fish eat?
Do fish chew their food? Fish do not chew their food the same way we do. Many carnivorous fishes (meat eating) use their sharp teeth to capture and hold prey while swallowing it whole or in large pieces. We use teeth to grind food into tiny pieces, and then we swallow.
Where do fish eat underwater?

How does a fish swallow?

How do fish get water?
In the case of freshwater fish, their blood and bodily fluids are much saltier than the water they swim in, so water will flow in through their gills. The opposite is true for saltwater fish. As well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems.
Do fish breathe through air or water?

What is the Diet of a fish?
