i think a submarine can stay underwater indefinetly but a submersible can only stay down for a limited time.
Without breathing, the world record is 22min With air bottles (scuba diver) or in a submarine you can of course stay longer. In a submarine when you have enough supplies, you can stay virtually forever under water.
three to five minutes
Paint does not affect how long the turtle can stay underwater..
Yes. The idea of the submarine is the element of surprise. Before nuclear power submarines ran on either battery power or diesel power. Every so often it needed to surface (or use a snorkle - no kidding, it's called a snorkle) to run the diesel (which would both propel the sub and charge the battery) Now, with nuclear power, the submarine can stay underwater as long as there is food for the crew. A submarine nuclear reactor can last for years.
A penguin can stay underwater for about 15 minutes and can go to a depth of 1700 feet.
The military submarines maintain depth by use of the planes. As they move through the water, a little up or down "tilt" on the planes will keep the boat at the correct depth.
Adult gray whales can stay underwater for approximately 10 - 15 minutes.
underwater.
It depends on the type of frog how long they can stay underwater. Some can stay underwater for their whole lives while some only stay for about 10 minutes.

A whale CAN drown- they cannot stay underwater indefinitely. When underwater, they hold their breath. They are REALLY good at holding their breath, and their bodies have adapted to doing that.
