Why are penguins black and white; it’s a really tricky question. As we know fish is the main diet of penguins. Therefore, they have to go in the oceans and find themselves a meal. But the ocean is not just full of their food; they come across some predators too.
Learn an interesting fact about penguins: Why can’t penguins fly.
In order to properly address why penguins are black and white, I would say that they are black and white to camouflage from prey. Their black side of the body helps them to be invisible to predators under the sea. The black color of skin really mixes things up with Deep Blue Ocean. Their color of the skin is not black actually; it is deep blue towards black; while the white side of their body prevents them from predators when they are on the surface of the ocean. It camouflages them in the sparkling blue water. There are some other good reasons for their black and white skin. As we know, that black color is the most heat absorbent; it helps them to get as many radiations as they can in cold climatic conditions. After huddling, penguins get a little warmer, in order to maintain the body temperature they are seen at the ocean lying with white side of body exposed. It helps them to drop their temperature a bit.
Why do Penguins Camouflage?
We all think penguins as a weak, timid and wobbling bird which is true up to some extent. They are not much powerful to fight predators. Therefore, they camouflage themselves to hide from predators. They play brains against muscles😜. They can hide in deep water and on surface of oceans. It is one of their best defense mechanism against predators.
What’s the purpose of black skin?
Penguins use their black skin as a defensive technique against predators. When spotted, they camouflage in deep water and become invisible.
Another good purpose of their black part of body is that, black color is the best heat absorbent of all colors. In cold climatic conditions where penguins live, it is in their best interest to get as much heat as they can. It keeps their body warm and lively.
What’s the purpose of white side?
This white side of penguin’s skin (belly) also helps them to be invisible from predators; they can’t be spotted from the bottom of the ocean while swimming at the surface. The sparkling light of sun camouflages them with surface water.
After huddling penguins get a little bit warmer than expected body temperature. To overcome this heat, their white colored skin, the most heat repellent color, is helpful.
How does the skin’s color help penguins maintain body temperature?
Black colored part is used to gain heat, if body temperature is low. Meanwhile, white colored skin proves to be beneficial if a penguin gets hot.
What is countershading?
Countershading also known as Thayer’s law is a process in which an animal or a bird camouflages its upper side of body with dark color and lower side with dull color. This technique helps penguins in their defensive values.
How countershading help penguins get prey?
Penguins counter shade them not just to hide from predators, but it also helps them find preys. Penguins’ dark skin makes them almost invisible for preys to be aware that they are being attacked. It increases their food availability in dark parts of the oceans.
