So they can swim longer.
yes they do, but they have an oil under their feathers which keeps them warm and also blubber (fat) which also keeps them warm.
Emperor penguins breathe through their lungs, taking in oxygen from the air and expelling carbon dioxide. When they are swimming underwater, emperor penguins can hold their breath for up to 18 minutes, utilizing their large lung capacity and efficient oxygen exchange system to dive deep for food.
Penguins have a respiratory system similar to other birds. They breathe air into their lungs, where oxygen is extracted and carbon dioxide is expelled. Penguins can dive underwater for extended periods of time due to adaptations such as increased oxygen storage capacity and efficient use of oxygen in their muscles.
Penguins dive for their food. Auks, which are similar to penguins, are smaller arctic birds that are able to fly and they dive for their food.
They can dive up to 500 feet deep.
Penguins use their lungs to breath.

Penguins dive in the sea and catch fish. Penguins are excellent swimmers and are very fast underwater.
Whales dive to get food. They come back to the surface to breathe.
Penguins have a fairly large lung capacity,allowing them to hold their breath for a certain period of time.
They don't breathe under water, certainly not like fish do. When they dive they hold their breath, just like whales and dolphins do when they dive. They close their nostrils as they dive to prevent water from coming into their lungs, just as whales/dolphins close their blow-holes before they dive or submerge themselves in the water.
