Divers explore underwater.
Diving bells work by trapping air inside a chamber, allowing divers to breathe and maintain pressure as they descend underwater. This air supply enables divers to explore the underwater world safely by providing a controlled environment for them to breathe and communicate while underwater.
He was he inventor of the SCUBA (Self-Contained Underwater Breathing Apparatus) equipment divers use to explore under the sea.
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.

There are many items underwater that are found in many places.
Sound travels faster underwater, but this does not mean that divers hear better underwater. It just means that the sound is heard more quickly.
I have seen this in tv. Some divers were underwater for about 3 minutes. I think it takes a life to achieve that.

Divers use substances with high density (ie. lead) to help them sink, and substances with low density (ie. air) to help them float. That way they control their bouyancy.
Divers usually increase their density by wearing a weight belt (which contains lead weights). Some divers also rely, to a lesser degree, on using steel tanks, which are more dense than aluminum tanks. To decrease their density, divers put air into a Bouyancy Control Device (BCD). Some divers may also control bouyancy by putting air into a drysuit if they wear one. Whereas the increase in density created by the weightbelt is normally fixed, the positive bouyancy provided by the BCD can be varied throughout the dive. Usually a divers net density will decrease over the dive - a diver with a full scuba tank has about 4.5 lbs of extra weight (the weight of the gas) over a diver with an empty scuba tank.
