In contrast to their dinosaur ancestors, they lack true teeth and have replaced them with specialized beaks and bills. Wings of penguins reduce heat loss by forming a countercurrent heat exchanger via the vascular design.

How do penguins keep themselves warm in cold water?
Penguins living in cold climates stay warm thanks to their thick feathers and blubber under the skin. Feathers are great on land, but not much help for keeping warm in the cold ocean. This is where the blubber layer comes in. Penguins stand up and rock backwards on their heels to reduce contact with the cold snow.
Some penguins live in warm weather places like the Galapagos Island where average temperature is 75 degrees Fahrenheit. Their layers of fat are not as thick as the penguins who live in cold climates. There are more penguins living in the warmer climates than colder climates.
6/ King and emperor penguins are able to tip up their feet, and rest their entire weight on a tripod of the heels and tail, reducing contact with the icy surface and so reducing heat loss. 7/ Penguin chicks and adults of some species huddle together to conserve heat.
You should be wondering “How do penguins survive in the cold weather?”
Penguins have 13 genes for protein that helps form their dense plumage. Their eyes have fewer genes compared to other birds but emperor penguins carry more genes for seeing in low light than Adélie penguins. They also carry several genes linked to thick skin disorders in humans, and more items.
How much energy does the emperor penguin save by maintaining temperature?
To simplify, according to our source, for each additional degree of Celsius that the Emperor Penguin maintains outside his body represents 7-17% reduction in energy loss.
Male emperor penguins will huddle together in groups of up to 6,000 while incubating their eggs during the middle of the Antarctic winter. 8/ Emperor penguins can recapture up to 80% of the heat escaping through their breath thanks to a complex heat exchange system in their nasal passages.
