I have seen this in tv. Some divers were underwater for about 3 minutes. I think it takes a life to achieve that.
Jacques Cousteau invented the Aqua-Lung to allow divers to explore underwater for longer periods without needing to surface frequently for air. This invention revolutionized underwater exploration by providing divers with the ability to breathe underwater using compressed air tanks.
Pearl divers typically use minimal equipment to enhance their underwater experience, such as goggles or masks for visibility, snorkels for breathing, and fins for better movement. In some cases, they may also utilize wetsuits for thermal protection and weight belts to help them descend. Advanced divers might use scuba gear, including tanks and regulators, to extend their time underwater and improve safety. Additionally, tools like nets or baskets can be used to collect oysters from the seabed.
By oxygen tanks - similar to SCUBA divers.
In water sports, a regulator refers to a device used in scuba diving that supplies air to divers from their tanks while maintaining a consistent pressure. It ensures that divers receive breathable air at varying depths, adjusting the pressure according to the surrounding water pressure. Regulators are crucial for safe diving, allowing for controlled breathing and reducing the risk of decompression sickness. They play a vital role in enabling divers to explore underwater environments safely.
Divers carry with them tanks containing air in them. The air present in these tanks has different composition from the normal air. It has 32% oxygen, 56% Nitrogen and 12% Helium. It is done so as to avoid creation of bends inside the body of divers when they come out of water.

The average aluminum SCUBA cylinder holds 80 cubic feet of air at pressure. That means you are taking the equivalent of a closet's worth of air and smashing it into a cylinder much smaller than that. When full, the cylinder is at 3,000 pounds per square inch of pressure.When the valve is opened, it sends air into the (assumed) first stage regulator which is connected by hoses to gear such as two second stage regulators, instruments and your vest.So the SCUBA tanks don't so much USE the air so much as STORE the air at high pressures.

Air tanks, also known as compressed air tanks or cylinders. These are used to store air under high pressure for different applications. MasterAire stands on hi-tech infrastructure that includes core expertise in the air compressor industry. They are commonly used in scuba diving, firefighting, and industrial settings. The tanks are filled with compressed air and then used to provide a portable supply of air when needed. In scuba diving, for example, divers carry air tanks to breathe underwater. The pressure in the tank forces air through a regulator, which reduces the pressure to a breathable level. These tanks are usually made of steel or aluminum for durability.
Divers wear tanks full of oxygen to help them breathe while they are under water. When the tanks start to get empty, they resurface.
Because fish have gills and can breathe under water and humans do not
It definitely would. Also, a tank filled with non-compressed air would be nearly impossible to use because air wouldn't flow out of it without an enormous amount of effort. For these reasons, all tanks used by divers are filled with compressed air.
