How are penguins able to dive so deep?
The penguins can switch between two modes of oxygen use — either starving their muscles or giving them an extra shot of oxygen to keep them working — to achieve their amazing dives. … They can only do this for a limited time, though, until blood oxygen levels become too low for the rest of the body.
How far can a penguin swim down?
Their wings act more like strong flippers allowing them to swim very fast. Penguins spend most of their lives in the water looking for food to feed themselves and their families. Most penguins swim to about 20 metres deep to look for food, but some species have been known to go as deep as 30 metres!
