They can drink salt water because their supraorbital gland filters excess salt from the bloodstream. [56] [57] [58] The salt is excreted in a concentrated fluid from the nasal passages. The great auk of the Northern Hemisphere, now extinct, was superficially similar to penguins, and the word penguin was
Living in saltwater environments would naturally pose a large problem for penguins because the ingestion of saltwater would be detrimental to a penguin's health. Although penguins do not directly drink water, it is taken in when they engulf prey. As a result, saltwater enters their system and must be effectively excreted. The supraorbital gland ...
Water: Penguins do not need fresh water. Indeed it is doubtful whether they drink water at all. Indeed it is doubtful whether they drink water at all. A salt load in their food is simply excreted via the nasal salt organs (no article on that, see Seabird ), which leaves the bird in fluid and osmotic equilibrium.
Magellanic penguins feed in the water, preying on small pelagic fish, hagfish, [5] cuttlefish, squid, krill, and other crustaceans, and ingest sea water with their prey. Their salt-excreting gland rids the salt from their bodies. Adult penguins can regularly dive to depths of 20 to 50 m (66 to 164 ft) deep in order to forage for prey.
The stones are supposed to keep penguin eggs above the water surface once colonies are filled with water from melting snow. Now we can't guarantee that this means happily ever after for the ...
Adélie penguins are faced with extreme osmotic conditions, as their frozen habitats offer little fresh water. Such desert conditions mean that the vast majority of the available water is highly saline, causing the diets of Adélie penguins to be heavy in salt. [48]
