Does a fish feel pain when hooked?

Why can’t fish breathe in air?

Why can’t humans breathe underwater?

The oxygen that fish breathe is not the oxygen in H2O. Humans cannot breathe underwater because our lungs do not have enough surface area to absorb enough oxygen from water, and the lining in our lungs is adapted to handle air rather than water.

Can a human get gills?

Since humans do not have gills, we cannot extract oxygen from water. Some marine mammals, like whales and dolphins, do live in water, but they don’t breathe it. They have developed a mechanism to hold their breath for long periods of time underwater.

Can a human breathe on Mars?

Mars does have an atmosphere, but it is about 100 times thinner than Earth’s atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.

Can you breathe in space?

Outer space is a vacuum. You cannot breathe in a vacuum because there’s literally no air to breathe, and if you tried, you’d be dead in about four minutes. Also, because space is extremely cold, your eyeballs could freeze solid, and even if you somehow survived, you’d be blind. There is no air.
