Penguins are generally great divers, but emperor penguins make the deepest and longest dives of all the penguin species. They can dive for 20 - 30 minutes at a time and reach depths of around meters over 1, feet. To stay underwater that long, penguins have developed the ability to control how and when their muscles use oxygen.
They can choose to either starve their muscles for oxygen or give them a boost to keep their muscles working during long dives. In 50 recorded dives ranging between 7 — 64 meters 23 — feet deep, the penguins stayed underwater anywhere from 2.
They can only do this for short periods of time, however, until blood oxygen levels become too low for the rest of their body. When this happens, penguins have to come back to the surface for air.
The downside of this penguin fact is that the adaptation leads to lactic acid build-up, so penguins will only do it if the prize a good dinner is worth it. It may seem like an obvious fact about Antarctic penguins that they have adapted to stay warm in supremely cold environments, but fewer people know how distinctly well-adapted their feet are to such temperatures. To keep their feet from freezing, penguins have special arteries in their legs that can adjust blood flow in response to foot temperature, enabling them to send just enough blood to their feet to keep them from freezing.
To maximine their use of their own heat, the warm blood on the way to their feet passes the blood that is coming back up to their bodies, resulting in the warmer blood heating the colder blood before it continues down to their feet.
To stay cool, penguins let heat escape from their beaks and not too surprisingly their feet.

NOO The North Norway cruise follows the path of more than one kind of whale as it travels amongst the fjords of Troms. The long Norway nights offer travellers on this expedition an excellent chance to take in the beauty and wonder of the Northern Lights.

How often do penguins drink water? How do penguins convert saltwater into freshwater? What animals dont have nipples? I had read somewhere about them being able to turn this into freshwater, and so wondered how do penguins turn saltwater into freshwater?
So how do penguins turn saltwater into freshwater? Rather the sodium chloride is filtered out of their blood stream by a gland called the supraorbital gland. This sits above the eye socket and works to filter out salt. This is then passed out through the penguins bill in the form of brine.
So the answer to the question of how do penguins turn saltwater into freshwater is a little more complex than just simply turning it from one thing to another.
Keep reading to find out more about this, as well as why penguins will drink sea water, and what else they can drink too! This really is a bit of a trick question, as technically penguins do not actually turn or convert saltwater into freshwater.
This actually goes against a lot of the misinformation I found when researching the answer to the question of how do penguins turn saltwater into freshwater. Rather they have a very clever way of removing the salt or sodium chloride. Interestingly, they are not the only marine birds that can do this. Due to spending a large amount of time both in and around water, marine birds will inevitably take in large amounts of saltwater.
As penguins do not pee or urinate, they need to find another way to get rid of the salt that they take in from the sea water. Like I said, penguins will drink a large amount of seawater. Sometimes this will be due to simply spending a lot of time swimming in the ocean, and sometimes because this is the only water available for them to drink.
I guess it has the same sort of result, just technically slightly different. The key answer to the question of how do penguins turn saltwater into freshwater lies in something called the supraorbital gland. This is a nasal gland found in penguins, and also in many other marine birds as well. Your question not on these pages? If you have a penguin question that is not answered here or elsewhere on the site, email your question and I'll try to answer it.
How do penguins sleep? Penguins sleep for a few minutes at a time any time of the day or night, wherever they are,although they sleep for longer periods on land and at night. They will sleep in a wide range of positions - sitting in the water, standing up, lying down, sitting or in some species, even perched in a tree. Crested penguins can often be seen sleeping with part of their bill tucked under a flipper.
