How Do Deep Sea Fish Survive the Extreme Pressure?

The video explains how atmospheric pressure increases underwater, affecting humans and marine life differently. While humans face severe risks at great depths, marine creatures have adapted to survive intense pressure. Fish and cetaceans have unique physiological adaptations, such as compressible lungs and special proteins, to withstand these conditions. However, there are limits to how deep they can go. Studying these creatures is challenging due to their need for high pressure environments.

What happens to the human body at the deepest point in the ocean?

• It expands due to low pressure.

• It gets crushed under extreme pressure.

• It experiences no change.

• It becomes buoyant and floats.

Why are fish able to withstand high pressures underwater?

• They have special air pockets.

• Their bodies are mostly water, which is not compressible.

• They have strong bones.

• They use lungs to breathe.

How do deep-sea diving mammals prevent nitrogen from entering their bloodstream?

• By collapsing their lungs to prevent gas exchange.

• By swimming at the surface.

• By using gills instead of lungs.

• By having non-compressible lungs.

What substance helps fish survive at great depths?

• Oxygen

• Myoglobin

• Trimethylamine oxide

• Hemoglobin

What is a common adaptation among deep-sea diving mammals?

• They can dissolve gases in their bloodstream.

• They have thicker skin.

• They breathe through their skin.

• They have larger lungs.
