How long can a macaroni penguin hold its breath?
Well, it depends on the penguin. A macaroni penguin can hold its breath for 20+ minutes, but a fairy penguin can only hold its breath for 15 or less minutes.
It's harder to hold your breath because there's no AIR & OXYGEN and 'cause in water if you hold your breath too long you die, but if you hold your breath in the air and if you think you are holding your breath too long you can just breath instead of trying to breath in the water. ~Its a phsycology thing.
there hold their breath for 97.00 min. For at least 30 mi but suprisingly enough they acually have to breath air to live but can 'hold their breath' for 30 straight minutes The Humoback whale can stay under water for 15 to 20 minutes max Because they are mammals to and can't hold their breath for very long.
