Because it gets its oxygen from the water through its gills.
Yes it is, as if you stay underwater for too long, your lungs can't take it, and you may choke/ faint. Only a few mammals (whales, dolphins, porpoises, etc.) can stay underwater for long periods of time.
no, but they can stay underwater for a long time
Hippos can stay underwater for up to six minutes at a time. Their nostrils close to keep water out and they hold their breath until it is time for more air.
Since a whale shark is really a shark rather than a whale (mammal) it does all its breathing through its gills. Although a whale shark can come to the surface, it does not need to do so in order to breath like a whale would. With that in mind, a whale shark can stay underwater from the moment it is born until the minute it dies of injury, disease, or old age. Since the life expectancy of a whale shark is around 70 years, that works out to be around 36,792,000 minutes.

by staying calm under water . you need to practise yoga.

Frogs can stay underwater for varying lengths of time, depending on the species and environmental conditions. For example, some frogs can stay submerged for several hours by absorbing oxygen through their skin, while others have adaptations that allow them to hold their breath for long periods. On average, a frog can typically stay underwater for 15-30 minutes before needing to come up for air.
The Bajau people, also known as the Sea Nomads, are known for their ability to stay underwater for extended periods of time.
so it has a longer time of having air
