not verylong because the water will start to enter the snorkel. LOL
Paint does not affect how long the turtle can stay underwater..
A snorkel is a breathing device that is used to dive in shallow areas of water. It has a goggle with a breathing tube attached so when a person goes underwater they can breath, but the tube has to stay above the water unlike skin diving.
A snorkel longer than 1 meter (about 3 feet) will make it impossible to breathe as the water pressure on the chest will make it impossible for him to expand his chest and fill his lungs. A diver below this depth will need to breathe pressurised air from a tank.
A penguin can stay underwater for about 15 minutes and can go to a depth of 1700 feet.
about a minute
20min
Adult gray whales can stay underwater for approximately 10 - 15 minutes.
they will be dead
40 minutes
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.
When diving with a snorkel in your mouth, it is important to take precautions to ensure a safe and enjoyable underwater experience. Make sure to always breathe slowly and steadily through the snorkel to avoid hyperventilation. Keep the snorkel clear of water by using a purge valve or blowing out any water that enters. Practice good buoyancy control to prevent accidental inhalation of water. Stay aware of your surroundings and avoid diving too deep or in strong currents. Lastly, always dive with a buddy for added safety.
Humans can't breathe underwater, unless assisted by either a snorkel or some other sort of air supply. With such a supply, there's really no limit to how long a human can stay, and breathe under water.
