Are emperor penguin and emperor penguin two names of the same kind of penguin?

Emperor penguins and emperor penguins are two independent penguins. There is also a very funny story: when people first discovered the emperor penguin, they were all shocked by its huge size-after all, other penguins were too small compared with the one-meter-high emperor penguin-so they were named the "king" of penguins. However, it was later discovered that there was another larger penguin. What should I do ... I can only call it the more distinguished "Emperor Penguin".

At first glance, these two kinds of penguins are really similar: the same huge body shape and the same gradual yellow feathers make many people confused. In fact, careful observation, it is not difficult to detect their differences:

The yellow feathers on the back of the emperor penguin's head are lighter in color, and the white parts of the abdomen and back of the head are not separated by black feathers.

Emperor penguins are different. The yellow feathers on the back of their heads are colorful and cut into comma shapes.

There is not much difference between the adult appearance of the two penguins, but the difference between the cubs is very different:

Although the emperor penguin is the largest penguin, its cubs are not big. Gray feathers and white patches on the cheeks are the signs to identify them.

Although king penguins are smaller than emperor penguins, their cubs are much larger than emperor penguins, and the color of their feathers has not changed, but they look like a bulging kiwi. ...

Although they look alike, are similar in size and even have similar names, emperor penguins and king penguins hardly meet each other. Emperor penguins are mostly distributed in the surrounding islands far away from the Antarctic, and emperor penguins are very few penguins who have spent their whole lives in the Antarctic continent. In fact, only emperor penguins and Adelie penguins breed in the Antarctic continent, and emperor penguins are the only penguins that will stay in the Antarctic at polar nights in the Antarctic continent.
